VPP PERFORMANCE TESTS - - **MRR Throughput**: MRR (Maximum Receive Rate) test code has now - configurable trial duration and number of consecutive executions. - Coverage of MRR tests has been extended across more test - scenarios. MRR tests are used for continuous performance trending - and for comparison between VPP releases. + - CSIT test environment is now versioned, with ver. 1 associated + with CSIT rls1908 git branch as of 2019-08-21, and ver. 2 + associated with CSIT rls2001 and master git branches as of + 2020-03-27. - - **MLRsearch Throughput**: MLRsearch algorithm has been introduced - for all NDR and PDR throughput tests. All tests that previously - used binary search got converted to MLRsearch. Coverage of NDR/PDR - tests has been extended across more test scenarios. + - 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. 2 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`. - - **L2patch Tests**: Tests measure performance of VPP L2patch, the - fastest L2 forwarding path implemented in VPP, that cross-links - RX and TX of two physical interfaces. +#. TEST FRAMEWORK - - **2-Node Tests**: A new baseline set of 2-node tests covering base - ip4, ip6, l2patch, l2bd, l2xc, running on new Xeon Skylake - testbeds. + - **CSIT PAPI support**: Due to issues with PAPI performance, VAT is + still used in CSIT for all VPP scale tests. See known issues below. - - **Generated tests**: Simplified and unified test structure, semi- - autogenerated by generator script. Test generator is currently - able to create test combinations with various frame size and - cores combinations. All existing test cases were converted to new - format. - - - **Simultaneous Multi-Threading**: SMT-aware detection of server - processor operation mode (HyperThreading enabled/disabled) with - associated compute resource configuration including thread - affinity, number of Rx queues and DPDK I/O mbufs. Tests are - automatically tagged during execution to indicate executed thread - configuration. + - **General Code Housekeeping**: Ongoing RF keywords optimizations, + removal of redundant RF keywords and aligning of suite/test + setup/teardowns. - - **Intel Xeon Skylake Support**: Support for 2-Node and 3-Node - physical testbed topologies based on the new SuperMirco servers - each with two Intel Xeon Skylake Platinum processors. Full - Ansible playbooks refactor for quick server (re)installation and - reference pointers of configuration. +#. PRESENTATION AND ANALYTICS LAYER -#. **Presentation and Analytics Layer** + - **Graphs layout improvements**: Improved performance graphs layout + for better readibility and maintenance: test grouping, axis + labels, descriptions, other informative decoration. - - **Performance trending**: Further improved continuous performance - trending with anomaly detection and analysis. +.. raw:: latex -#. **Test Framework Optimizations** + \clearpage - - **General Code Housekeeping**: Ongoing RF keywords optimizations, - removal of redundant RF keywords. +.. _vpp_known_issues: 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.
