Once the tests are fully integrated and results become available, -they will be published as an addendum to the current version of CSIT |release| -report. +.. _vpp_performance_tests_release_notes: + +Release Notes +============= + +Changes in |csit-release| +------------------------- + +#. VPP PERFORMANCE TESTS + + - **Regressions with DPDK drivers**: Change from DPDK v21.08 to DPDK + v21.11 introduced regression across all tests using dpdk + drivers (with dpdk_plugin loaded). Compared to previous VPP + release performance drop varies in the range of -15% to -6%, + depending on test. It is related to updated MTU checks within + DPDK code and associated VPP code changes. See + `VPP v2202 release notes `_ + and :ref:`vpp_known_issues`. + + - **Number of CSIT 9000B frame tests failing**: tests with higher + encapsulation overhead are failing due to exceeding default + Ethernet Maximum Frame Size value that has been reduced by MTU + related VPP code changes. See + `VPP v2202 release notes `_ + and :ref:`vpp_known_issues`. + + - **Intel Xeon Ice Lake**: Performance test data for these platforms + is now provided by testbeds newly installed in FD.io CSIT labs. + For details about the physical setup see + :ref:`physical_testbeds_2n_icx` and + :ref:`physical_testbeds_3n_icx`. + + - **Arm Ampere Altra**: Performance test data for these platforms + is now provided by testbeds newly installed in FD.io CSIT labs. + For details about the physical setup see + :ref:`physical_testbeds_3n_alt`. + + - **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. + + - **RC2 coverage test data is used for 2n-icx test bed**: There is only + one 2n-icx test bed and the amount of tests is large (same as 2n-skx with 4 + test beds), so we decided to use test data already available from RC2 + testing. + +#. TEST FRAMEWORK + + - **CSIT test environment** version has been updated to ver. 10, see + :ref:`test_environment_versioning`. + + - **CSIT PAPI support**: Due to issues with PAPI performance, and + deprecation of VAT, VPP CLI is used in CSIT for many VPP scale + tests. See :ref:`vpp_known_issues`. + + - **General Code Housekeeping**: Ongoing code optimizations and bug + fixes. + +#.
