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:`performance_test_methodology` section - for more details. + - CSIT test environment is versioned, see + :ref:`test_environment_versioning`. - - **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. + - To identify performance changes due to VPP code changes from + v20.05.0 to v20.09.0, both have been tested in CSIT environment + ver. 5 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`. - - **3n-skx tests**: Added performamce tests for 3n-skx (3-Node Xeon - Skylake) testbeds: VM vhost and Container memif tests. + - **NAT44 tests**: Adapted existing and added new tests. - - **VXLAN Scale Tests**: Added performamce tests for VXLAN scale with - dot1q and VPP L2BD. + - Refactored NAT44 deterministic mode (nat44det) tests to use separate + det44 vpp plugin and to use the same scheme of inside and outside + addresses and ports, as used in new NAT44 endpoint-dependent mode tests. - - **AVF Driver Tests**: Added performamce tests for i40e AVF driver - on VPP, no DPDK required. + - Added new NAT44 endpoint-depended mode uni-directional (nat44ed-udir) + tests that measure packet throughput in one direction with usage of TRex + in stateless mode. - - **QAT**: Fixed reoccuring issues with QAT crypto accelerator cards. + - Added new NAT44 endpoint-dependent mode CPS tests that measure + connections per second with usage of TRex in stateful mode. + NOTE: CPS measurement data will be added in two weeks. - - **VM Vhost Virtio Params Combinations**: Added performance tests - for VM vhost with different virtio parameters combinations: - indirect buffers, mergeable buffers. + - **IPSec async mode tests**: Added VPP performance tests for async crypto + engine. - - **K8s/Ligato in Trending**: Added K8s/Ligato Container memif tests - to daily trending. + - **AMD 2n-zn2 testbed**: New physical testbed type installed in FD.io CSIT, + VPP performance data will be added in upcoming weeks. #. 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:`performance_test_methodology` section for more details. + - **TRex ASTF**: Added capability to run TRex in advanced stateful mode. - - **Trending Tests BMRR**: Used new Burst MRR (BMRR) tests for daily - trending. - - - **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. - - - **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"). + - **CSIT PAPI support**: Due to issues with PAPI performance, VAT is + still used in CSIT for all VPP scale tests. See known issues below. - **General Code Housekeeping**: Ongoing RF keywords optimizations, - removal of redundant RF keywords. - -#. PRESENTATION AND ANALYTICS LAYER + removal of redundant RF keywords and aligning of suite/test + setup/teardowns. - - **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(!) + - **Intel E810CQ 100G NIC**: Added configuration for Intel E810CQ 100G NIC. + No tests run for this NIC as it is not present in FD.io CSIT lab yet. +#. PRESENTATION AND ANALYTICS LAYER - - **Performance Trending**: Further improvements of continuous - performance trending, anomaly detection and analysis. - -#. MISCELLANEOUS - - - **3n-dnv Tests (3rd Party)**: Published performance tests for 3n- - dnv (3-Node Atom Denverton) from 3rd party testbeds running FD.io - |csit-release| automated testing code. + - **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. .. raw:: latex @@ -90,24 +65,48 @@ Changes in |csit-release| Known Issues ------------ -List of known issues in |csit-release| for VPP performance tests: - -+----+-----------------------------------------+---------------------------------------------------------------------------------------------------------------------------------+ -| # | JiraID | Issue Description | -+====+=========================================+=================================================================================================================================+ -| 1 | `CSIT-570 | Sporadic (1 in 200) NDR discovery test failures on x520.
