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. - -#.
