VPP PERFORMANCE TESTS - - - **Intel Xeon Ice Lake**: Performance test data for these platforms - continues to be provided by external Intel benchmarking labs - executing |csit-release| tests.

TEST FRAMEWORK - - - **CSIT test environment** version has been updated to ver. 9, see - :ref:`test_environment_versioning`. - - - **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. - - - **General Code Housekeeping**: Ongoing code optimizations and bug - fixes. - -#.
