Yardstick test results

Yardstick test tesult document overview

This document provides an overview of the results of test cases developed by the OPNFV Yardstick Project, executed on OPNFV community labs.

Yardstick project is described in Yardstick user guide.

Yardstick is run systematically at the end of an OPNFV fresh installation. The system under test (SUT) is installed by the installer Apex, Compass, Fuel or Joid on Performance Optimized Datacenter (POD); One single installer per POD. All the runnable test cases are run sequentially. The installer and the POD are considered to evaluate whether the test case can be run or not. That is why all the number of test cases may vary from 1 installer to another and from 1 POD to POD.

OPNFV CI provides automated build, deploy and testing for the software developed in OPNFV. Unless stated, the reported tests are automated via Jenkins Jobs. Yardsrick test results from OPNFV Continous Integration can be found in the following dashboard:

  • Yardstick Dashboard: uses influx DB to store Yardstick CI test results and

    Grafana for visualization (user: opnfv/ password: opnfv)

The results of executed test cases are available in Dashboard and all logs are stored in Jenkins.

It was not possible to execute the entire Yardstick test cases suite on the PODs assigned for release verification over a longer period of time, due to continuous work on the software components and blocking faults either on environment, features or test framework.

The list of scenarios supported by each installer can be described as follows:

To qualify for release, the scenarios must have deployed and been successfully tested in four consecutive installations to establish stability of deployment and feature capability. It is a recommendation to run Yardstick test cases over a longer period of time in order to better understand the behavior of the system under test.

Overview of test results

See Grafana for viewing test result metrics for each respective test case. It is possible to chose which specific scenarios to look at, and then to zoom in on the details of each run test scenario as well.

All of the test case results below are based on 4 scenario test runs, each run on the LF POD1 between August 25 and 28 in 2016.

TC002

The round-trip-time (RTT) between 2 VMs on different blades is measured using ping. Most test run measurements result on average between 0.74 and 1.08 ms. A few runs start with a 0.99 - 1.07 ms RTT spike (This could be because of normal ARP handling). One test run has a greater RTT spike of 1.35 ms. To be able to draw conclusions more runs should be made. SLA set to 10 ms. The SLA value is used as a reference, it has not been defined by OPNFV.

TC005

The IO read bandwidth looks similar between different dates, with an average between approx. 128 and 136 MB/s. Within each test run the results vary, with a minimum 5 MB/s and maximum 446 MB/s on the totality. Most runs have a minimum BW of 5 MB/s (one run at 6 MB/s). The maximum BW varies more in absolute numbers between the dates, between 416 and 446 MB/s. SLA set to 400 MB/s. The SLA value is used as a reference, it has not been defined by OPNFV.

TC010

The measurements for memory latency are similar between test dates and result in approx. 1.09 ns. The variations within each test run are similar, between 1.0860 and 1.0880 ns. SLA set to 30 ns. The SLA value is used as a reference, it has not been defined by OPNFV.

TC011

Packet delay variation between 2 VMs on different blades is measured using Iperf3. The reported packet delay variation varies between 0.0025 and 0.0148 ms, with an average delay variation between 0.0056 ms and 0.0157 ms.

TC012

Between test dates, the average measurements for memory bandwidth result in approx. 19.70 GB/s. Within each test run the results vary more, with a minimal BW of 18.16 GB/s and maximum of 20.13 GB/s on the totality. SLA set to 15 GB/s. The SLA value is used as a reference, it has not been defined by OPNFV.

TC014

The Unixbench processor test run results vary between scores 3224.4 and 3842.8, one result each date. The average score on the total is 3659.5. No SLA set.

TC037

The amount of packets per second (PPS) and round trip times (RTT) between 2 VMs on different blades are measured when increasing the amount of UDP flows sent between the VMs using pktgen as packet generator tool.

Round trip times and packet throughput between VMs can typically be affected by the amount of flows set up and result in higher RTT and less PPS throughput.

The RTT results are similar throughout the different test dates and runs at approx. 15 ms. Some test runs show an increase with many flows, in the range towards 16 to 17 ms. One exception standing out is Feb. 15 where the average RTT is stable at approx. 13 ms. The PPS results are not as consistent as the RTT results. In some test runs when running with less than approx. 10000 flows the PPS throughput is normally flatter compared to when running with more flows, after which the PPS throughput decreases. Around 20 percent decrease in the worst case. For the other test runs there is however no significant change to the PPS throughput when the number of flows are increased. In some test runs the PPS is also greater with 1000000 flows compared to other test runs where the PPS result is less with only 2 flows.

The average PPS throughput in the different runs varies between 414000 and 452000 PPS. The total amount of packets in each test run is approx. 7500000 to 8200000 packets. One test run Feb. 15 sticks out with a PPS average of 558000 and approx. 1100000 packets in total (same as the on mentioned earlier for RTT results).

There are lost packets reported in most of the test runs. There is no observed correlation between the amount of flows and the amount of lost packets. The lost amount of packets normally range between 100 and 1000 per test run, but there are spikes in the range of 10000 lost packets as well, and even more in a rare cases.

CPU utilization statistics are collected during UDP flows sent between the VMs using pktgen as packet generator tool. The average measurements for CPU utilization ratio vary between 1% to 2%. The peak of CPU utilization ratio appears around 7%.

TC069

Between test dates, the average measurements for memory bandwidth vary between 22.6 and 29.1 GB/s. Within each test run the results vary more, with a minimal BW of 20.0 GB/s and maximum of 29.5 GB/s on the totality. SLA set to 6 GB/s. The SLA value is used as a reference, it has not been defined by OPNFV.

Overview of test results

See Grafana for viewing test result metrics for each respective test case. It is possible to chose which specific scenarios to look at, and then to zoom in on the details of each run test scenario as well.

All of the test case results below are based on 4 scenario test runs, each run on the Intel POD5 between September 11 and 14 in 2016.

TC002

The round-trip-time (RTT) between 2 VMs on different blades is measured using ping. Most test run measurements result on average between 1.59 and 1.70 ms. Two test runs have reached the same greater RTT spike of 3.06 ms, which are 1.66 and 1.70 ms average, but only one has the lower RTT of 1.35 ms. The other two runs have no similar spike at all. To be able to draw conclusions more runs should be made. SLA set to be 10 ms. The SLA value is used as a reference, it has not been defined by OPNFV.

TC005

The IO read bandwidth actually refers to the storage throughput and the greatest IO read bandwidth of the four runs is 173.3 MB/s. The IO read bandwidth of the four runs looks similar on different four days, with an average between 32.7 and 60.4 MB/s. One of the runs has a minimum BW of 429 KM/s and other has a maximum BW of 173.3 MB/s. The SLA of read bandwidth sets to be 400 MB/s, which is used as a reference, and it has not been defined by OPNFV.

TC010

The tool we use to measure memory read latency is lmbench, which is a series of micro benchmarks intended to measure basic operating system and hardware system metrics. The memory read latency of the four runs is 1.1 ns on average. The variations within each test run are different, some vary from a large range and others have a small change. For example, the largest change is on September 14, the memory read latency of which is ranging from 1.12 ns to 1.22 ns. However, the results on September 12 change very little, which range from 1.14 ns to 1.17 ns. The SLA sets to be 30 ns. The SLA value is used as a reference, it has not been defined by OPNFV.

TC011

Iperf3 is a tool for evaluating the pocket delay variation between 2 VMs on different blades. The reported pocket delay variations of the four test runs differ from each other. The results on September 13 within the date look similar and the values are between 0.0087 and 0.0190 ms, which is 0.0126 ms on average. However, on the fourth day, the pocket delay variation has a large wide change within the date, which ranges from 0.0032 ms to 0.0121 ms and has the minimum average value. The pocket delay variations of other two test runs look relatively similar, which are 0.0076 ms and 0.0152 ms on average. The SLA value sets to be 10 ms. The SLA value is used as a reference, it has not been defined by OPNFV.

TC012

Lmbench is also used to measure the memory read and write bandwidth, in which we use bw_mem to obtain the results. Among the four test runs, the memory bandwidth within the second day almost keep stable, which is 11.58 GB/s on average. And the memory bandwidth of the fourth day look similar as that of the second day, both of which remain stable. The other two test runs relatively change from a large wide range, in which the minimum memory bandwidth is 11.22 GB/s and the maximum bandwidth is 16.65 GB/s with an average bandwidth of about 12.20 GB/s. Here SLA set to be 15 GB/s. The SLA value is used as a reference, it has not been defined by OPNFV.

TC014

The Unixbench is used to measure processing speed, that is instructions per second. It can be seen from the dashboard that the processing test results vary from scores 3272 to 3444, and there is only one result one date. The overall average score is 3371. No SLA set.

TC037

The amount of packets per second (PPS) and round trip times (RTT) between 2 VMs on different blades are measured when increasing the amount of UDP flows sent between the VMs using pktgen as packet generator tool.

Round trip times and packet throughput between VMs can typically be affected by the amount of flows set up and result in higher RTT and less PPS throughput.

The mean packet throughput of the four test runs is 119.85, 128.02, 121.40 and 126.08 kpps, of which the result of the second is the highest. The RTT results of all the test runs keep flat at approx. 37 ms. It is obvious that the PPS results are not as consistent as the RTT results.

The No. flows of the four test runs are 240 k on average and the PPS results look a little waved since the largest packet throughput is 184 kpps and the minimum throughput is 49 K respectively.

There are no errors of packets received in the four runs, but there are still lost packets in all the test runs. The RTT values obtained by ping of the four runs have the similar average vaue, that is 38 ms, of which the worest RTT is 93 ms on Sep. 14th.

CPU load of the four test runs have a large change, since the minimum value and the peak of CPU load is 0 percent and 51 percent respectively. And the best result is obtained on Sep. 14th.

TC069

With the block size changing from 1 kb to 512 kb, the memory write bandwidth tends to become larger first and then smaller within every run test, which rangs from 22.3 GB/s to 26.8 GB/s and then to 18.5 GB/s on average. Since the test id is one, it is that only the INT memory write bandwidth is tested. On the whole, when the block size is 8 kb and 16 kb, the memory write bandwidth look similar with a minimal BW of 22.5 GB/s and peak value of 28.7 GB/s. SLA sets to be 7 GB/s. The SLA value is used as a a reference, it has not been defined by OPNFV.

TC070

Round trip times and packet throughput between VMs can typically be affected by the amount of flows set up and result in higher RTT and less PPS throughput.

The network latency is measured by ping, and the results of the four test runs look similar with each other. Within each test run, the maximum RTT can reach more than 80 ms and the average RTT is usually approx. 38 ms. On the whole, the average RTTs of the four runs keep flat.

Memory utilization is measured by free, which can display amount of free and used memory in the system. The largest amount of used memory is 268 MiB on Sep 14, which also has the largest minimum memory. Besides, the rest three test runs have the similar used memory. On the other hand, the free memory of the four runs have the same smallest minimum value, that is about 223 MiB, and the maximum free memory of three runs have the similar result, that is 337 MiB, except that on Sep. 14th, whose maximum free memory is 254 MiB. On the whole, all the test runs have similar average free memory.

Network throughput and packet loss can be measured by pktgen, which is a tool in the network for generating traffic loads for network experiments. The mean network throughput of the four test runs seem quite different, ranging from 119.85 kpps to 128.02 kpps. The average number of flows in these tests is 24000, and each run has a minimum number of flows of 2 and a maximum number of flows of 1.001 Mil. At the same time, the corresponding packet throughput differ between 49.4k and 193.3k with an average packet throughput of approx. 125k. On the whole, the PPS results seem consistent. Within each test run of the four runs, when number of flows becomes larger, the packet throughput seems not larger in the meantime.

TC071

The RTT results are similar throughout the different test dates and runs at approx. 32 ms. The PPS results are not as consistent as the RTT results.

Network utilization is measured by sar, that is system activity reporter, which can display the average statistics for the time since the system was started. Network utilization statistics are collected during UDP flows sent between the VMs using pktgen as packet generator tool. The largest total number of packets transmitted per second differs from each other, in which the smallest number of packets transmitted per second is 6 pps on Sep. 12ed and the largest of that is 210.8 kpps. Meanwhile, the largest total number of packets received per second differs from each other, in which the smallest number of packets received per second is 2 pps on Sep. 13rd and the largest of that is 250.2 kpps.

In some test runs when running with less than approx. 90000 flows the PPS throughput is normally flatter compared to when running with more flows, after which the PPS throughput decreases. For the other test runs there is however no significant change to the PPS throughput when the number of flows are increased. In some test runs the PPS is also greater with 1000000 flows compared to other test runs where the PPS result is less with only 2 flows.

There are lost packets reported in most of the test runs. There is no observed correlation between the amount of flows and the amount of lost packets. The lost amount of packets normally differs a lot per test run.

Conclusions and recommendations

The pktgen test configuration has a relatively large base effect on RTT in TC037 compared to TC002, where there is no background load at all. Approx. 15 ms compared to approx. 0.5 ms, which is more than a 3000 percentage difference in RTT results. Especially RTT and throughput come out with better results than for instance the fuel-os-nosdn-nofeature-ha scenario does. The reason for this should probably be further analyzed and understood. Also of interest could be to make further analyzes to find patterns and reasons for lost traffic. Also of interest could be to see if there are continuous variations where some test cases stand out with better or worse results than the general test case.

Overview of test results

See Grafana for viewing test result metrics for each respective test case. It is possible to chose which specific scenarios to look at, and then to zoom in on the details of each run test scenario as well.

All of the test case results below are based on 4 scenario test runs, each run on the Intel POD6 between September 1 and 8 in 2016.

TC002

The round-trip-time (RTT) between 2 VMs on different blades is measured using ping. Most test run measurements result on average between 1.01 ms and 1.88 ms. Only one test run has reached greatest RTT spike of 1.88 ms. Meanwhile, the smallest network latency is 1.01 ms, which is obtained on Sep. 1st. In general, the average of network latency of the four test runs are between 1.29 ms and 1.34 ms. SLA set to be 10 ms. The SLA value is used as a reference, it has not been defined by OPNFV.

TC005

The IO read bandwidth actually refers to the storage throughput, which is measured by fio and the greatest IO read bandwidth of the four runs is 183.65 MB/s. The IO read bandwidth of the three runs looks similar, with an average between 62.9 and 64.3 MB/s, except one on Sep. 1, for its maximum storage throughput is only 159.1 MB/s. One of the runs has a minimum BW of 685 KB/s and other has a maximum BW of 183.6 MB/s. The SLA of read bandwidth sets to be 400 MB/s, which is used as a reference, and it has not been defined by OPNFV.

The results of storage IOPS for the four runs look similar with each other. The IO read times per second of the four test runs have an average value between 1.41k per second and 1.64k per second, and meanwhile, the minimum result is only 55 times per second.

TC010

The tool we use to measure memory read latency is lmbench, which is a series of micro benchmarks intended to measure basic operating system and hardware system metrics. The memory read latency of the four runs is between 1.152 ns and 1.179 ns on average. The variations within each test run are quite different, some vary from a large range and others have a small change. For example, the largest change is on September 8, the memory read latency of which is ranging from 1.120 ns to 1.221 ns. However, the results on September 7 change very little. The SLA sets to be 30 ns. The SLA value is used as a reference, it has not been defined by OPNFV.

TC011

Iperf3 is a tool for evaluating the packet delay variation between 2 VMs on different blades. The reported packet delay variations of the four test runs differ from each other. In general, the packet delay of the first two runs look similar, for they both stay stable within each run. And the mean packet delay of them are 0.0087 ms and 0.0127 ms respectively. Of the four runs, the fourth has the worst result, because the packet delay reaches 0.0187 ms. The SLA value sets to be 10 ms. The SLA value is used as a reference, it has not been defined by OPNFV.

TC012

Lmbench is also used to measure the memory read and write bandwidth, in which we use bw_mem to obtain the results. Among the four test runs, the trend of three memory bandwidth almost look similar, which all have a narrow range, and the average result is 11.78 GB/s. Here SLA set to be 15 GB/s. The SLA value is used as a reference, it has not been defined by OPNFV.

TC014

The Unixbench is used to evaluate the IaaS processing speed with regards to score of single cpu running and parallel running. It can be seen from the dashboard that the processing test results vary from scores 3260k to 3328k, and there is only one result one date. No SLA set.

TC037

The amount of packets per second (PPS) and round trip times (RTT) between 2 VMs on different blades are measured when increasing the amount of UDP flows sent between the VMs using pktgen as packet generator tool.

Round trip times and packet throughput between VMs can typically be affected by the amount of flows set up and result in higher RTT and less PPS throughput.

The mean packet throughput of the four test runs is between 307.3 kpps and 447.1 kpps, of which the result of the third run is the highest. The RTT results of all the test runs keep flat at approx. 15 ms. It is obvious that the PPS results are not as consistent as the RTT results.

The No. flows of the four test runs are 240 k on average and the PPS results look a little waved since the largest packet throughput is 418.1 kpps and the minimum throughput is 326.5 kpps respectively.

There are no errors of packets received in the four runs, but there are still lost packets in all the test runs. The RTT values obtained by ping of the four runs have the similar average vaue, that is approx. 15 ms.

CPU load is measured by mpstat, and CPU load of the four test runs seem a little similar, since the minimum value and the peak of CPU load is between 0 percent and nine percent respectively. And the best result is obtained on Sep. 1, with an CPU load of nine percent. But on the whole, the CPU load is very poor, since the average value is quite small.

TC069

With the block size changing from 1 kb to 512 kb, the memory write bandwidth tends to become larger first and then smaller within every run test, which rangs from 21.9 GB/s to 25.9 GB/s and then to 17.8 GB/s on average. Since the test id is one, it is that only the INT memory write bandwidth is tested. On the whole, when the block size is 2 kb or 16 kb, the memory write bandwidth look similar with a minimal BW of 24.8 GB/s and peak value of 27.8 GB/s. And then with the block size becoming larger, the memory write bandwidth tends to decrease. SLA sets to be 7 GB/s. The SLA value is used as a reference, it has not been defined by OPNFV.

TC070

The amount of packets per second (PPS) and round trip times (RTT) between 2 VMs on different blades are measured when increasing the amount of UDP flows sent between the VMs using pktgen as packet generator tool.

Round trip times and packet throughput between VMs can typically be affected by the amount of flows set up and result in higher RTT and less PPS throughput.

The network latency is measured by ping, and the results of the four test runs look similar with each other, and within these test runs, the maximum RTT can reach 39 ms and the average RTT is usually approx. 15 ms. The network latency tested on Sep. 1 and Sep. 8 have a peak latency of 39 ms. But on the whole, the average RTTs of the five runs keep flat and the network latency is relatively short.

Memory utilization is measured by free, which can display amount of free and used memory in the system. The largest amount of used memory is 267 MiB for the four runs. In general, the four test runs have very large memory utilization, which can reach 257 MiB on average. On the other hand, for the mean free memory, the four test runs have the similar trend with that of the mean used memory. In general, the mean free memory change from 233 MiB to 241 MiB.

Packet throughput and packet loss can be measured by pktgen, which is a tool in the network for generating traffic loads for network experiments. The mean packet throughput of the four test runs seem quite different, ranging from 305.3 kpps to 447.1 kpps. The average number of flows in these tests is 240000, and each run has a minimum number of flows of 2 and a maximum number of flows of 1.001 Mil. At the same time, the corresponding average packet throughput is between 354.4 kpps and 381.8 kpps. In summary, the PPS results seem consistent. Within each test run of the four runs, when number of flows becomes larger, the packet throughput seems not larger at the same time.

TC071

The amount of packets per second (PPS) and round trip times (RTT) between 2 VMs on different blades are measured when increasing the amount of UDP flows sent between the VMs using pktgen as packet generator tool.

Round trip times and packet throughput between VMs can typically be affected by the amount of flows set up and result in higher RTT and less PPS throughput.

The network latency is measured by ping, and the results of the four test runs look similar with each other. Within each test run, the maximum RTT is only 42 ms and the average RTT is usually approx. 15 ms. On the whole, the average RTTs of the four runs keep stable and the network latency is relatively small.

Cache utilization is measured by cachestat, which can display size of cache and buffer in the system. Cache utilization statistics are collected during UDP flows sent between the VMs using pktgen as packet generator tool. The largest cache size is 212 MiB, which is same for the four runs, and the smallest cache size is 75 MiB. On the whole, the average cache size of the four runs look the same and is between 197 MiB and 211 MiB. Meanwhile, the tread of the buffer size keep flat, since they have a minimum value of 7 MiB and a maximum value of 8 MiB, with an average value of about 7.9 MiB.

Packet throughput can be measured by pktgen, which is a tool in the network for generating traffic loads for network experiments. The mean packet throughput of the four test runs differ from 354.4 kpps to 381.8 kpps. The average number of flows in these tests is 240k, and each run has a minimum number of flows of 2 and a maximum number of flows of 1.001 Mil. At the same time, the corresponding packet throughput differ between 305.3 kpps to 447.1 kpps. Within each test run of the four runs, when number of flows becomes larger, the packet throughput seems not larger in the meantime.

TC072

The amount of packets per second (PPS) and round trip times (RTT) between 2 VMs on different blades are measured when increasing the amount of UDP flows sent between the VMs using pktgen as packet generator tool.

Round trip times and packet throughput between VMs can typically be affected by the amount of flows set up and result in higher RTT and less PPS throughput.

The RTT results are similar throughout the different test dates and runs between 0 ms and 42 ms with an average leatency of less than 15 ms. The PPS results are not as consistent as the RTT results, for the mean packet throughput of the four runs differ from 354.4 kpps to 381.8 kpps.

Network utilization is measured by sar, that is system activity reporter, which can display the average statistics for the time since the system was started. Network utilization statistics are collected during UDP flows sent between the VMs using pktgen as packet generator tool. The largest total number of packets transmitted per second look similar for three test runs, whose values change a lot from 10 pps to 501 kpps. While results of the rest test run seem the same and keep stable with the average number of packets transmitted per second of 10 pps. However, the total number of packets received per second of the four runs look similar, which have a large wide range of 2 pps to 815 kpps.

In some test runs when running with less than approx. 251000 flows the PPS throughput is normally flatter compared to when running with more flows, after which the PPS throughput decreases. For the other test runs there is however no significant change to the PPS throughput when the number of flows are increased. In some test runs the PPS is also greater with 251000 flows compared to other test runs where the PPS result is less with only 2 flows.

There are lost packets reported in most of the test runs. There is no observed correlation between the amount of flows and the amount of lost packets. The lost amount of packets normally differs a lot per test run.

Round trip times and packet throughput between VMs can typically be affected by the amount of flows set up and result in higher RTT and less PPS throughput.

The RTT results are similar throughout the different test dates and runs at approx. 15 ms. Some test runs show an increase with many flows, in the range towards 16 to 17 ms. One exception standing out is Feb. 15 where the average RTT is stable at approx. 13 ms. The PPS results are not as consistent as the RTT results. In some test runs when running with less than approx. 10000 flows the PPS throughput is normally flatter compared to when running with more flows, after which the PPS throughput decreases. Around 20 percent decrease in the worst case. For the other test runs there is however no significant change to the PPS throughput when the number of flows are increased.

There are lost packets reported in most of the test runs. There is no observed correlation between the amount of flows and the amount of lost packets. The lost amount of packets normally range between 100 and 1000 per test run, but there are spikes in the range of 10000 lost packets as well, and even more in a rare cases.

Memory utilization statistics are collected during UDP flows sent between the VMs using pktgen as packet generator tool. The average measurements for memory utilization vary between 225MB to 246MB. The peak of memory utilization appears around 340MB.

TC071

The amount of packets per second (PPS) and round trip times (RTT) between 2 VMs on different blades are measured when increasing the amount of UDP flows sent between the VMs using pktgen as packet generator tool.

Round trip times and packet throughput between VMs can typically be affected by the amount of flows set up and result in higher RTT and less PPS throughput.

The RTT results are similar throughout the different test dates and runs at approx. 15 ms. Some test runs show an increase with many flows, in the range towards 16 to 17 ms. One exception standing out is Feb. 15 where the average RTT is stable at approx. 13 ms. The PPS results are not as consistent as the RTT results. In some test runs when running with less than approx. 10000 flows the PPS throughput is normally flatter compared to when running with more flows, after which the PPS throughput decreases. Around 20 percent decrease in the worst case. For the other test runs there is however no significant change to the PPS throughput when the number of flows are increased. In some test runs the PPS is also greater with 1000000 flows compared to other test runs where the PPS result is less with only 2 flows.

The average PPS throughput in the different runs varies between 414000 and 452000 PPS. The total amount of packets in each test run is approx. 7500000 to 8200000 packets.

Rationale for decisions

Pass

Tests were successfully executed and metrics collected. No SLA was verified. To be decided on in next release of OPNFV.

Conclusions and recommendations

The pktgen test configuration has a relatively large base effect on RTT in TC037 compared to TC002, where there is no background load at all. Approx. 15 ms compared to approx. 0.5 ms, which is more than a 3000 percentage difference in RTT results. Especially RTT and throughput come out with better results than for instance the fuel-os-nosdn-nofeature-ha scenario does. The reason for this should probably be further analyzed and understood. Also of interest could be to make further analyzes to find patterns and reasons for lost traffic. Also of interest could be to see if there are continuous variations where some test cases stand out with better or worse results than the general test case.

Overview of test results

See Grafana for viewing test result metrics for each respective test case. It is possible to chose which specific scenarios to look at, and then to zoom in on the details of each run test scenario as well.

All of the test case results below are based on 4 scenario test runs, each run on the Intel POD6 between September 8 and 11 in 2016.

TC002

The round-trip-time (RTT) between 2 VMs on different blades is measured using ping. Most test run measurements result on average between 1.35 ms and 1.57 ms. Only one test run has reached greatest RTT spike of 2.58 ms. Meanwhile, the smallest network latency is 1.11 ms, which is obtained on Sep. 11st. In general, the average of network latency of the four test runs are between 1.35 ms and 1.57 ms. SLA set to be 10 ms. The SLA value is used as a reference, it has not been defined by OPNFV.

TC005

The IO read bandwidth actually refers to the storage throughput, which is measured by fio and the greatest IO read bandwidth of the four runs is 175.4 MB/s. The IO read bandwidth of the three runs looks similar, with an average between 43.7 and 56.3 MB/s, except one on Sep. 8, for its maximum storage throughput is only 107.9 MB/s. One of the runs has a minimum BW of 478 KM/s and other has a maximum BW of 168.6 MB/s. The SLA of read bandwidth sets to be 400 MB/s, which is used as a reference, and it has not been defined by OPNFV.

The results of storage IOPS for the four runs look similar with each other. The IO read times per second of the four test runs have an average value between 978 per second and 1.20 K/s, and meanwhile, the minimum result is only 36 times per second.

TC010

The tool we use to measure memory read latency is lmbench, which is a series of micro benchmarks intended to measure basic operating system and hardware system metrics. The memory read latency of the four runs is between 1.164 ns and 1.244 ns on average. The variations within each test run are quite different, some vary from a large range and others have a small change. For example, the largest change is on September 10, the memory read latency of which is ranging from 1.128 ns to 1.381 ns. However, the results on September 11 change very little. The SLA sets to be 30 ns. The SLA value is used as a reference, it has not been defined by OPNFV.

TC011

Iperf3 is a tool for evaluating the packet delay variation between 2 VMs on different blades. The reported packet delay variations of the four test runs differ from each other. In general, the packet delay of two runs look similar, for they both stay stable within each run. And the mean packet delay of them are 0.0772 ms and 0.0788 ms respectively. Of the four runs, the fourth has the worst result, because the packet delay reaches 0.0838 ms. The rest one has a large wide range from 0.0666 ms to 0.0798 ms. The SLA value sets to be 10 ms. The SLA value is used as a reference, it has not been defined by OPNFV.

TC012

Lmbench is also used to measure the memory read and write bandwidth, in which we use bw_mem to obtain the results. Among the four test runs, the trend of the memory bandwidth almost look similar, which all have a large wide range, and the minimum and maximum results are 9.02 GB/s and 18.14 GB/s. Here SLA set to be 15 GB/s. The SLA value is used as a reference, it has not been defined by OPNFV.

TC014

The Unixbench is used to evaluate the IaaS processing speed with regards to score of single cpu running and parallel running. It can be seen from the dashboard that the processing test results vary from scores 3395 to 3475, and there is only one result one date. No SLA set.

TC037

The amount of packets per second (PPS) and round trip times (RTT) between 2 VMs on different blades are measured when increasing the amount of UDP flows sent between the VMs using pktgen as packet generator tool.

Round trip times and packet throughput between VMs can typically be affected by the amount of flows set up and result in higher RTT and less PPS throughput.

The mean packet throughput of the four test runs is between 362.1 kpps and 363.5 kpps, of which the result of the third run is the highest. The RTT results of all the test runs keep flat at approx. 17 ms. It is obvious that the PPS results are not as consistent as the RTT results.

The No. flows of the four test runs are 240 k on average and the PPS results look a little waved since the largest packet throughput is 418.1 kpps and the minimum throughput is 326.5 kpps respectively.

There are no errors of packets received in the four runs, but there are still lost packets in all the test runs. The RTT values obtained by ping of the four runs have the similar average vaue, that is approx. 17 ms, of which the worst RTT is 39 ms on Sep. 11st.

CPU load is measured by mpstat, and CPU load of the four test runs seem a little similar, since the minimum value and the peak of CPU load is between 0 percent and nine percent respectively. And the best result is obtained on Sep. 10, with an CPU load of nine percent.

TC069

With the block size changing from 1 kb to 512 kb, the memory write bandwidth tends to become larger first and then smaller within every run test, which rangs from 25.9 GB/s to 26.6 GB/s and then to 18.1 GB/s on average. Since the test id is one, it is that only the INT memory write bandwidth is tested. On the whole, when the block size is from 2 kb to 16 kb, the memory write bandwidth look similar with a minimal BW of 22.1 GB/s and peak value of 28.6 GB/s. And then with the block size becoming larger, the memory write bandwidth tends to decrease. SLA sets to be 7 GB/s. The SLA value is used as a reference, it has not been defined by OPNFV.

TC070

The amount of packets per second (PPS) and round trip times (RTT) between 2 VMs on different blades are measured when increasing the amount of UDP flows sent between the VMs using pktgen as packet generator tool.

Round trip times and packet throughput between VMs can typically be affected by the amount of flows set up and result in higher RTT and less PPS throughput.

The network latency is measured by ping, and the results of the four test runs look similar with each other, and within these test runs, the maximum RTT can reach 39 ms and the average RTT is usually approx. 17 ms. The network latency tested on Sep. 11 shows that it has a peak latency of 39 ms. But on the whole, the average RTTs of the five runs keep flat and the network latency is relatively short.

Memory utilization is measured by free, which can display amount of free and used memory in the system. The largest amount of used memory is 270 MiB on the first two runs. In general, the mean used memory of two test runs have very large memory utilization, which can reach 264 MiB on average. And the other two runs have a large wide range of memory usage with the minimum value of 150 MiB and the maximum value of 270 MiB. On the other hand, for the mean free memory, the four test runs have the similar trend with that of the mean used memory. In general, the mean free memory change from 220 MiB to 342 MiB.

Packet throughput and packet loss can be measured by pktgen, which is a tool in the network for generating traffic loads for network experiments. The mean packet throughput of the four test runs seem quite different, ranging from 326.5 kpps to 418.1 kpps. The average number of flows in these tests is 240000, and each run has a minimum number of flows of 2 and a maximum number of flows of 1.001 Mil. At the same time, the corresponding packet throughput differ between 326.5 kpps and 418.1 kpps with an average packet throughput between 361.7 kpps and 363.5 kpps. In summary, the PPS results seem consistent. Within each test run of the four runs, when number of flows becomes larger, the packet throughput seems not larger at the same time.

TC071

The amount of packets per second (PPS) and round trip times (RTT) between 2 VMs on different blades are measured when increasing the amount of UDP flows sent between the VMs using pktgen as packet generator tool.

Round trip times and packet throughput between VMs can typically be affected by the amount of flows set up and result in higher RTT and less PPS throughput.

The network latency is measured by ping, and the results of the four test runs look similar with each other. Within each test run, the maximum RTT is only 47 ms and the average RTT is usually approx. 15 ms. On the whole, the average RTTs of the four runs keep stable and the network latency is relatively small.

Cache utilization is measured by cachestat, which can display size of cache and buffer in the system. Cache utilization statistics are collected during UDP flows sent between the VMs using pktgen as packet generator tool. The largest cache size is 214 MiB, which is same for the four runs, and the smallest cache size is 94 MiB. On the whole, the average cache size of the four runs look the same and is between 198 MiB and 207 MiB. Meanwhile, the tread of the buffer size keep flat, since they have a minimum value of 7 MiB and a maximum value of 8 MiB, with an average value of about 7.9 MiB.

Packet throughput can be measured by pktgen, which is a tool in the network for generating traffic loads for network experiments. The mean packet throughput of the four test runs seem quite the same, which is approx. 363 kpps. The average number of flows in these tests is 240k, and each run has a minimum number of flows of 2 and a maximum number of flows of 1.001 Mil. At the same time, the corresponding packet throughput differ between 327 kpps and 418 kpps with an average packet throughput of about 363 kpps. Within each test run of the four runs, when number of flows becomes larger, the packet throughput seems not larger in the meantime.

TC072

The amount of packets per second (PPS) and round trip times (RTT) between 2 VMs on different blades are measured when increasing the amount of UDP flows sent between the VMs using pktgen as packet generator tool.

Round trip times and packet throughput between VMs can typically be affected by the amount of flows set up and result in higher RTT and less PPS throughput.

The RTT results are similar throughout the different test dates and runs between 0 ms and 47 ms with an average leatency of less than 16 ms. The PPS results are not as consistent as the RTT results, for the mean packet throughput of the four runs differ from 361.7 kpps to 365.0 kpps.

Network utilization is measured by sar, that is system activity reporter, which can display the average statistics for the time since the system was started. Network utilization statistics are collected during UDP flows sent between the VMs using pktgen as packet generator tool. The largest total number of packets transmitted per second look similar for two test runs, whose values change a lot from 10 pps to 432 kpps. While results of the other test runs seem the same and keep stable with the average number of packets transmitted per second of 10 pps. However, the total number of packets received per second of the four runs look similar, which have a large wide range of 2 pps to 657 kpps.

In some test runs when running with less than approx. 250000 flows the PPS throughput is normally flatter compared to when running with more flows, after which the PPS throughput decreases. For the other test runs there is however no significant change to the PPS throughput when the number of flows are increased. In some test runs the PPS is also greater with 250000 flows compared to other test runs where the PPS result is less with only 2 flows.

There are lost packets reported in most of the test runs. There is no observed correlation between the amount of flows and the amount of lost packets. The lost amount of packets normally differs a lot per test run.
