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 6 scenario test +runs, each run on the Ericsson POD2_ between February 13 and 24 in 2016. Test +case TC011_ is the greater exception for which there are only 2 test runs +available, due to earlier problems with InfluxDB test result population. +The best would be to have more runs to draw better conclusions from, but these +are the only runs available at the time of OPNFV R2 release. + +TC002 +----- +The round-trip-time (RTT) between 2 VMs on different blades is measured using +ping. Most test run measurements result on average between 0.3 and 0.5 ms, but +one date (Feb. 23) sticks out with an RTT average of 1 ms. +A few runs start with a 1 - 2 ms RTT spike (This could be because of normal ARP +handling). One test run has a greater RTT spike of 3.9 ms, which is the same +one with the 0.9 ms average. The other runs have no similar spike at all. +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. 165 and 185 MB/s. Within each test run the results +vary, with a minimum 2 MB/s and maximum 617 MB/s on the totality. Most runs +have a minimum BW of 3 MB/s (two runs at 2 MB/s). The maximum BW varies more in +absolute numbers between the dates, between 566 and 617 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. 1.2 ns. The variations within each test run are similar, between +1.215 and 1.219 ns. One exception is February 16, where the average is 1.222 +and varies between 1.22 and 1.28 ns. +SLA set to 30 ns. The SLA value is used as a reference, it has not been defined +by OPNFV. + +TC011 +----- +Only 2 test runs are available to report results on. + +Packet delay variation between 2 VMs on different blades is measured using +Iperf3. On the first date the reported packet delay variation varies between +0.0025 and 0.011 ms, with an average delay variation of 0.0067 ms. +On the second date the delay variation varies between 0.002 and 0.006 ms, with +an average delay variation of 0.004 ms. + +TC012 +----- +Results are reported for 5 test runs. It is not known why the 6:th test run +is missing. +Between test dates the average measurements for memory bandwidth vary between +17.4 and 17.9 GB/s. Within each test run the results vary more, with a minimal +BW of 16.4 GB/s and maximum of 18.2 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 +----- +Results are reported for 5 test runs. It is not known why the 6:th test run +is missing. +The Unixbench processor test run results vary between scores 3080 and 3240, +one result each date. The average score on the total is 3150. +No SLA set. + +TC037 +----- +Results are reported for 5 test runs. It is not currently known why the 6:th +test run is missing. +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.

Conclusions and recommendations ------------------------------- - -.. did the expected behavior occured? +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. |
