VPP performance test environment changes +#. **VPP performance tests** - - Further optimizations of VM and vhost-user test environment - various - Qemu virtio queue size testing with value of 256 and 1024. Applied - Linux CFS optimization to run VPP worker threads and Qemu worker threads - with highest priority. + - *MRR tests* - New Maximum Receive Rate tests measure the packet + forwarding rate under the maximum load offered by traffic + generator over a set trial duration, regardless of packet loss. + MRR tests are used for continuous performance trending and for + comparison between releases. -#. VPP performance test framework changes + - *Service Chaining with SRv6* - New SRv6 (Segment Routing IPv6) proxy + tests measure performance of SRv6 Endpoint fronting SR-unaware + appliance via masquerading (End.AM), dynamic proxy (End.AD) or + static proxy (End.AS) SR functions. - - Full code review, optimization and refactor. +#. **Presentation and Analytics Layer** -#. T-rex changes + - *Performance trending* - Added continuous performance trending and + analysis. New Performance Trending and Performance Analysis jobs + executed regular throughput tests, with results being subsequently + analysed and trend and anomalies summarized and presented in VPP + Performance Dashboard and trendline graphs. - - Full refactor of T-rex driver and introduce of traffic profiles that - improves readability, manageability of traffic profiles for various - test scenarios. +#. **Test Framework Optimizations** -#. Added VPP performance tests + - *Performance tests efficiency* - Qemu build/install optimizations, + warmup phase handling, vpp restart handling. Resulted in improved + stability and reduced total execution time by 30% for single pkt + size e.g. 64B/78B. - - **LXC memif** + - *General code housekeeping* - ongoing RF keywords optimizations, + removal of redundant RF keywords. - - Memif interface tests interconnecting two VPP instances on single SUT. - Master VPP instance running on native OS with Intel x520 NIC and guest - VPP instance running in Linux Container (LXC) doing the L2 cross - connect loop. LXC running in privileged mode is pinned to dedicated - cores. All VPP instances are same version. +Performance Changes +------------------- - - **Stateful Security Groups** +Relative performance changes in measured packet throughput in CSIT +|release| are calculated against the results from CSIT |release-1| +report. Listed mean and standard deviation values are computed based on +a series of the same tests executed against respective VPP releases to +verify test results repeatibility, with percentage change calculated for +mean values. Note that the standard deviation is quite high for a small +number of packet throughput tests, what indicates poor test results +repeatability and makes the relative change of mean throughput value not +fully representative for these tests.
