+ `increase from 7 to 8 cores and pinning cores to interfaces <https://gerrit.fd.io/r/c/csit/+/28184>`_
+ for better TRex performance with symmetric traffic profiles.

To identify performance changes due to VPP code development from
-v20.01.0 to v20.05.0, both have been tested in CSIT environment ver. 4
+v20.05.0 to v20.09.0, both have been tested in CSIT environment ver. 5
and compared against each other. All substantial progressions and
-regressions have been marked up with RCA analysis.
+regressions have been marked up with RCA analysis. See

-CSIT environment ver. 4 has been evaluated against the ver. 2 by
-benchmarking VPP v20.01.0 in both environment versions.
