VPP PERFORMANCE TESTS - **Intel Xeon 2n-skx, 3n-skx testbeds**: VPP performance test data - is not included in this report version.

Due to substantial impact + of test environment changes (applied during the CSIT-2001 + development cycle) on the performance of VPP software, a new + approach to performance comparison and progression/regression + root cause analysis (RCA) has been applied. + + - 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 git branch as of 2020-03-27. + + - To identify performance changes due to CSIT test environment + changes from ver. 1 to ver. 2, VPP v19.08.1 has been re-tested in + ver. 2 and compared against the past results obtained with + testing in ver. 1.
