VPP PERFORMANCE TESTS + + - **Added new performance testbed 3n-snr** (3 Node SnowRidge, with Intel + Atom processors). + + - **Added GTPU HW offload tests** using VPP GTPU hardware offload + with Intel e810 4p25ge NICs (3n-icx testbeds only). These tests + were already there in CSIT-2206, but were yielding invalid + results due to using TRex v2.97 that was incompatible with e810 + NICs used for those tests. + + - **Added Wireguard tests** using VPP software crypto (3n-icx, 3n-snr + testbeds) and using built-in hardware crypto QAT device (3n-snr testbed + only). + + - **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. + +#. TEST FRAMEWORK + + - CSIT-2210 executes all VPP v22.10 performance tests using vpp ubuntu2204 + images, due to CSIT execution environment change as noted below. This + applies to all performance testbeds except Denverton. Consequently, VPP + v22.06 has not been re-tested in CSIT-2210 environment, as no ubuntu204 + images are available for that VPP version. Performance comparison + between VPP v22.10 (current version) vs VPP v22.06 (previous version) + may be impacted by VPP build environment change (ubuntu2004 to ubuntu + 2204) change and CSIT environment change. See :ref:`vpp_rca` for + details. + + - **CSIT test environment** version has been updated to ver. 11, see + :ref:`test_environment_versioning`. + + - **TCP TPUT profiles** had to be changed, as newer TRex versions + are not deterministic enough when deciding when to send an ACK. + + - **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. + +#.
