- **TRex** TRex Traffic Generator version, drivers and configuration
tracked in `TG Settings
- <https://docs.fd.io/csit/master/report/vpp_performance_tests/test_environment.html#tg-settings-trex>`_.
+ <https://s3-docs.fd.io/csit/master/report/vpp_performance_tests/test_environment.html#tg-settings-trex>`_.
- **CSIT** CSIT framework code tracked in CSIT release branches.
Following is the list of CSIT versions to date:
`TRex
<https://docs.fd.io/csit/rls2005/report/vpp_performance_tests/test_environment.html#tg-settings-trex>`_,
`CSIT <https://git.fd.io/csit/tree/?h=rls2005>`_).
-
-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
-and compared against each other. All substantial progressions and
-regressions have been marked up with RCA analysis.
+- Ver. 5 associated with CSIT rls2009 branch (`HW
+ <https://git.fd.io/csit/tree/docs/lab?h=rls2009>`_, `Linux
+ <https://docs.fd.io/csit/rls2009/report/vpp_performance_tests/test_environment.html#sut-settings-linux>`_,
+ `TRex
+ <https://docs.fd.io/csit/rls2009/report/vpp_performance_tests/test_environment.html#tg-settings-trex>`_,
+ `CSIT <https://git.fd.io/csit/tree/?h=rls2009>`_).
+
+ - The main change is TRex data-plane core resource adjustments:
+ `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.
+- Ver. 6 associated with CSIT rls2101 branch (`HW
+ <https://git.fd.io/csit/tree/docs/lab?h=rls2101>`_, `Linux
+ <https://docs.fd.io/csit/rls2101/report/vpp_performance_tests/test_environment.html#sut-settings-linux>`_,
+ `TRex
+ <https://docs.fd.io/csit/rls2101/report/vpp_performance_tests/test_environment.html#tg-settings-trex>`_,
+ `CSIT <https://git.fd.io/csit/tree/?h=rls2101>`_).
+
+ - The main change is TRex version upgrade:
+ `increase from 2.82 to 2.86 <https://gerrit.fd.io/r/c/csit/+/29980>`_.
+- Ver. 7 associated with CSIT rls2106 branch (`HW
+ <https://git.fd.io/csit/tree/docs/lab?h=rls2106>`_, `Linux
+ <https://s3-docs.fd.io/csit/rls2106/report/vpp_performance_tests/test_environment.html#sut-settings-linux>`_,
+ `TRex

+ `CSIT <https://git.fd.io/csit/tree/?h=rls2106>`_).
+
+ - TRex version upgrade:
+ `increase from 2.86 to 2.88 <https://gerrit.fd.io/r/c/csit/+/31652>`_.
+ - Ubuntu upgrade:
+ `upgrade from 18.04 LTS to 20.04.2 LTS <https://gerrit.fd.io/r/c/csit/+/31290>`_.
+
+To identify performance changes due to VPP code development between previous
+and current VPP release version, both have been tested in CSIT environment of
+latest version and compared against each other. All substantial progressions and
+regressions have been marked up with RCA analysis. See
:ref:`vpp_throughput_comparisons` and :ref:`vpp_known_issues`.
-CSIT environment ver. 4 has been evaluated against the ver. 2 by
-benchmarking VPP v20.01.0 in both environment versions.

Physical Testbeds
-----------------
server as TG both connected in ring topology.
Tested SUT servers are based on a range of processors including Intel
-Xeon Haswell-SP, Intel Xeon Skylake-SP, Intel Xeon Cascade Lake-SP, Arm,
+Intel Xeon Skylake-SP, Intel Xeon Cascade Lake-SP, Arm,
Intel Atom. More detailed description is provided in
:ref:`tested_physical_topologies`. Tested logical topologies are
described in :ref:`tested_logical_topologies`.
