VPP PERFORMANCE TESTS - - CSIT test environment is now versioned, with ver. 1 associated - with CSIT rls1908 git branch as of 2019-08-21, and ver. 2 - associated with CSIT rls2001 and master git branches as of - 2020-03-27. - - - To identify performance changes due to VPP code changes from - v20.01.0 to v20.05.0, both have been tested in CSIT environment - ver. 2 and compared against each other. All substantial - progressions has been marked up with RCA analysis.

TEST FRAMEWORK + - **TRex ASTF**: Improved capability to run TRex in advanced stateful mode. + - **CSIT PAPI support**: Due to issues with PAPI performance, VAT is still used in CSIT for all VPP scale tests.
