Changes in |csit-release|
-------------------------
-#. **DPDK performance tests**
-
- - *MRR tests* - Maximum Receive Rate tests measure the packet forwarding rate
- under the maximum load offered by traffic generator over a set trial
- duration, regardless of packet loss. MRR tests are used for continuous
- performance trending and for comparison between releases.
-
- - *MLR tests* - NDR and PDR tests measure the packet forwarding rate using
- MLRsearch library by traffic generator. All tests that previously used
- binary search were converted to MLRsearch.
-
- - *2-node tests* - Set of 2-node tests covering testpmd and l3fwd.
-
- - Increased coverage of NIC specific tests (Intel-xxv710-da2, Intel-x710)
-
- - *Generated tests* - Simplified and unified test structure,
- semi-autogenerated by generator script. Test generator is currently able
- to create test combinations with various frame size and cores combinations.
- All existing test cases were converted to new format.
-
-
-Performance Changes
--------------------
-
-Relative performance changes in measured packet throughput in |csit-release|
-are calculated against the results from |csit-release-1|
-report. Listed mean and standard deviation values are computed based on
-a series of the same tests executed against respective DPDK releases to
-verify test results repeatability, with percentage change calculated for
-mean values.

+#. DPDK PERFORMANCE TESTS
+
+ - **Intel Xeon 2n-skx, 3n-skx and 2n-clx testbeds**: Testpmd and
+ L3fwd performance test data is not included in this report
+ version. This is due to the lower performance and behaviour
+ inconsistency of these systems following the upgrade of processor
+ microcode packages (skx ucode 0x2000064, clx ucode 0x500002c) as
+ part of updating Ubuntu 18.04 LTS kernel version. Tested VPP and
+ DPDK applications (L3fwd) are affected. Skx and Clx test data
+ will be added in subsequent maintenance report version(s) once
+ the issue is resolved. See :ref:`dpdk_known_issues`.
+
+#. DPDK RELEASE VERSION CHANGE
+
+ - |csit-release| tested |dpdk-release|, as used by |vpp-release|.
+
+#. TEST ENVIRONMENT
+
+ - **TRex Fortville NIC Performance**: Received FVL fix from Intel
+ resolving TRex low throughput issue. TRex per FVL NIC throughput
+ increased from ~27 Mpps to the nominal ~37 Mpps. For detail see
+ `CSIT-1503 <https://jira.fd.io/browse/CSIT-1503>`_ and `TRex-519
+ <https://trex-tgn.cisco.com/youtrack/issue/trex-519>`_].
+
+ - **New Intel Xeon Cascadelake Testbeds**: Added performance tests
+ for 2-Node-Cascadelake (2n-clx) testbeds with x710, xxv710 and
+ mcx556a-edat NIC cards.
+
+..
+ // Alternative Note for 1st Bullet when bad microcode Skx, Clx results are published
+ - **Intel Xeon 2n-skx, 3n-skx and 2n-clx testbeds**: Testpmd and
+ L3fwd performance test data is included in this report version,
+ but it shows lower performance and behaviour inconsistency of
+ these systems following the upgrade of processor microcode
+ packages (skx ucode 0x2000064, clx ucode 0x500002c) as part of
+ updating Ubuntu 18.04 LTS kernel version. Tested VPP and DPDK
+ applications (L3fwd) are affected. Skx and Clx test data will be
+ corrected in subsequent maintenance report version(s) once the
+ issue is resolved. See :ref:`vpp_known_issues`.
