VPP PERFORMANCE TESTS - - **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. + - **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`. -#. TEST FRAMEWORK + - **AWS EC2 c5n**: Performance test data for AWS c5n instances has + been added to report for ip4, ip6 and ipsec tests. + + - **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. - - **Container code optimizations**: Optimized container library allows to - run containre_memif tests faster. +#. TEST FRAMEWORK - - **CSIT PAPI Support**: Continue converting existing VAT L1 keywords to - PAPI L1 KWs in CSIT using VPP Python bindings. Required for migrating away - from VAT. + - **CSIT test environment** version has been updated to ver. 8, see + :ref:`test_environment_versioning`. - - **General Code Housekeeping**: Ongoing RF keywords optimizations, - removal of redundant RF keywords. + - **CSIT in AWS environment**: Completed CSIT automation support for + AWS c5n instances environment, including weekly performance + trending tests execution. -#. PRESENTATION AND ANALYTICS LAYER + - **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. - - **Graphs Layout Improvements**: Improved performance graphs layout - for better readibility and maintenance: test grouping, axis - labels, descriptions, other informative decoration. + - **General Code Housekeeping**: Ongoing code optimizations and bug + fixes. -#.
