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 5 consecutive scenario test -runs, each run on the Ericsson POD2_ between February 13 and 18 in 2016. 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. The measurements are on average varying between 0.5 and 1.1 ms -with a first 2 - 2.5 ms RTT spike in the beginning of each run (This could be -because of normal ARP handling). The 2 last runs are very similar in their -results. But, to be able to draw any further conclusions more runs should be -made. There is one measurement taken on February 16 that does not have the -first RTT spike, and less variations to the RTT. The reason for this is -unknown. There is a discussion on another test measurement made Feb. 16 in -TC037_. -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 look similar between different test runs, with an -average at approx. 160-170 MB/s. Within each run the results vary much, -minimum 2 MB/s and maximum 630 MB/s on the totality. Most runs have a -minimum of 3 MB/s (one run at 2 MB/s). The maximum BW varies much more in -absolute numbers, between 566 and 630 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 consistent among test runs and results -in approx. 1.2 ns. The variations between runs are similar, between -1.215 and 1.219 ns. One exception is February 16, where the varation is -greater, 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 ------ -For this scenario no results are available to report on. Probable reason is -an integer/floating point issue regarding how InfluxDB is populated with -result data from the test runs. - -TC012 ------ -The average measurements for memory bandwidth are consistent among most of the -different test runs at 17.2 - 17.3 GB/s. The very first test run averages at -17.7 GB/s. Within each run the results vary, with a minimal BW of 15.4 -GB/s and maximum of 18.2 GB/s of 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 single and parallel speed scores show similar results -at approx. 3200. The runs vary between scores 3160 and 3240. -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 are typically affected by -the amount of flows set up and result in higher RTT and less PPS -throughput. - -When running with less than 10000 flows the results are flat and consistent. -RTT is then approx. 30 ms and the number of PPS remains flat at approx. -250000 PPS. Beyond approx. 10000 flows and up to 1000000 (one million) there -is an even drop in RTT and PPS performance, eventually ending up at approx. -150-250 ms and 40000 PPS respectively. - -There is one measurement made February 16 that has slightly worse results -compared to the other 4 measurements. The reason for this is unknown. For -instance anyone being logged onto the POD can be of relevance for such a -disturbance. - -Detailed test results ---------------------- -The scenario was run on Ericsson POD2_ with: -Fuel 8.0 -OpenStack Liberty -OVS 2.3.1 - -No SDN controller installed - -Rationale for decisions ------------------------ -Pass - -Tests were successfully executed and metrics collects (apart from TC011_). -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 (30 ms -compared to 1 ms or less, which is more than a 3000 percentage different -in RTT results). The larger amounts of flows in TC037 generate worse -RTT results, in the magnitude of several hundreds of milliseconds. It would -be interesting to also make and compare all these measurements to completely -(optimized) bare metal machines running native Linux with all other relevant -tools available, e.g. lmbench, pktgen etc. -- cgit 1.2.3-korg
