VPP PERFORMANCE TESTS - - **BMRR Throughput**: MRR (Maximum Receive Rate) test code has been - updated with a configurable burst MRR parameters: trial duration - and number of trials in a single burst. Enables a new Burst MRR - (BMRR for short) methodology for more precise performance - trending. See updated :ref:`test_methodology` section - for more details. - - - **2n-skx tests**: Added performamce tests for 2n-skx (2-Node Xeon - Skylake) testbeds: focus on baseline and scale tests, including - VM vhost and Container memif tests. - - - **3n-skx tests**: Added performamce tests for 3n-skx (3-Node Xeon - Skylake) testbeds: VM vhost and Container memif tests. - - - **VXLAN Scale Tests**: Added performamce tests for VXLAN scale with - dot1q and VPP L2BD. - - - **AVF Driver Tests**: Added performamce tests for i40e AVF driver - on VPP, no DPDK required. - - - **QAT**: Fixed reoccuring issues with QAT crypto accelerator cards. + - **Intel Xeon Ice Lake**: Performance test data for these platforms + continues to be provided by external Intel benchmarking labs + executing |csit-release| tests. For details about the physical + setup see :ref:`tested_physical_topologies`. - - **VM Vhost Virtio Params Combinations**: Added performance tests - for VM vhost with different virtio parameters combinations: - indirect buffers, mergeable buffers. + - **AWS EC2 c5n**: Performance test data for AWS c5n instances has + been added to report for ip4, ip6 and ipsec tests. - - **K8s/Ligato in Trending**: Added K8s/Ligato Container memif tests - to daily trending. + - **Reduction of tests**: Removed certain test variations executed + iteratively for the report (as well as in daily and weekly + trending) due to physical testbeds overload. #. TEST FRAMEWORK - - **Experimental Soak Tests**: Added performamce soak tests framework - code for extended time duration tests and throughput discovery - at given PLR and at give total test time e.g. minutes, hours, - days, weeks, months, years. See updated - :ref:`test_methodology` section for more details. + - **CSIT test environment** version has been updated to ver. 8, see + :ref:`test_environment_versioning`. - - **Trending Tests BMRR**: Used new Burst MRR (BMRR) tests for daily - trending. + - **CSIT in AWS environment**: Completed CSIT automation support for + AWS c5n instances environment, including weekly performance + trending tests execution. - - **Per VPP Patch Performance Checks**: Per VPP gerrit patch vs. - parent performance tests, anomaly detection and no verify voting - (-1/0/+1) yet. Manual trigger only. Not "marketed" to FD.io - community yet to avoid excessive LFN FD.io physical performance - testbed blocking. + - **CSIT PAPI support**: Due to issues with PAPI performance, and + deprecation of VAT, CLI is used in CSIT for many VPP scale tests. + See known issues below. - - **Patch-on-Patch Infra**: Added capability to run performance tests - using CSIT gerrit patch code testing VPP gerrit patch code, i.e. - before any VPP and/or CSIT code is merged into git branch. - - - **CSIT PAPI Support**: Initial implementation of PAPI L1 KWs in - CSIT using VPP Python bindings. Required for migraing away from - VAT. Very few L1 KWs implemented ("show version", "show - interfaces"). - - - **General Code Housekeeping**: Ongoing RF keywords optimizations, - removal of redundant RF keywords. + - **General Code Housekeeping**: Ongoing code optimizations and bug + fixes. #. PRESENTATION AND ANALYTICS LAYER - - **Graphs Layout Improvements**: Improved performance graphs layout - for better readibility and maintenance: test grouping, axis - labels, descriptions, other informative decoration. Master report - generated. 744 graphs(!) - - - **Performance Trending**: Further improvements of continuous - performance trending, anomaly detection and analysis. - -#.
