Changes in |csit-release|
-------------------------
-No code changes apart from bug fixes.
+#. DPDK PERFORMANCE TESTS
-Performance Changes
--------------------
+ - **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`.
-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 VPP releases to
-verify test results repeatability, with percentage change calculated for
-mean values. Note that the standard deviation is quite high for a small
-number of packet throughput tests, what indicates poor test results
-repeatability and makes the relative change of mean throughput value not
-fully representative for these tests. The root causes behind poor
-results repeatability vary between the test cases.
