Changes in |csit-release|
-------------------------
+#. 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
+ cx556a-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`.
