VPP PERFORMANCE TESTS - - *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. + - CSIT test environment is versioned, see + :ref:`test_environment_versioning`. - - *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. + - To identify performance changes due to VPP code changes from + v20.01.0 to v20.05.0, both have been tested in CSIT environment + ver. 4 and compared against each other. All substantial + progressions has been marked up with RCA analysis. See + :ref:`vpp_compare_current_vs_previous_release` and + :ref:`vpp_known_issues`. -#. **Presentation and Analytics Layer** +#. TEST FRAMEWORK - - *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. + - **CSIT PAPI support**: Due to issues with PAPI performance, VAT is + still used in CSIT for all VPP scale tests. See known issues below. -#. **Test Framework Optimizations** + - **General Code Housekeeping**: Ongoing RF keywords optimizations, + removal of redundant RF keywords and aligning of suite/test + setup/teardowns. - - *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. +#. PRESENTATION AND ANALYTICS LAYER - - *General code housekeeping* - ongoing RF keywords optimizations, - removal of redundant RF keywords. + - **Graphs improvements**: Added possibility to use Gbps on Y-axis in + Packet Throughput and Speedup Multi-Core graphs, added unidirectional + mode to the Latency graphs. -Performance Changes -------------------- +.. raw:: latex -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.
