VPP PERFORMANCE TESTS - - - CSIT test environment is versioned, see - :ref:`test_environment_versioning`. - - - **Upgrade to Ubuntu 20.04 LTS**: Reinstall base operating system to Ubuntu - 20.04.2 LTS. Upgrade includes also baseline Docker containers used for - spawning topology. - - - **AF_XDP**: Added af_xdp driver testing for all testcases. - - - **GTPU tunnel**: Added GTPU HW Offload IPv4 routing tests. - - - **Telemetry retouch**: Redesign telemetry retrieval from DUT. Include - VPP perfmon plugin telemetry. - -#. TEST FRAMEWORK - - - **CSIT PAPI support**: Due to issues with PAPI performance, VAT is - still used in CSIT for all VPP scale tests. See known issues below. - - - **General Code Housekeeping**: Ongoing code optimizations, - speed ups and bug fixes. - -#.
