Changes in |csit-release|
-------------------------
-#. **DPDK release version change**
-
- - |csit-release| tested DPDK-18.05, as used by |vpp-release|.
-
-#. **DPDK performance tests**
-
- - **MRR Throughput**: MRR (Maximum Receive Rate) test code has now
- configurable trial duration and number of consecutive executions.
- Coverage of MRR tests has been extended across more test
- scenarios. MRR tests are used for continuous performance trending.
-
- - **MLRsearch Throughput**: MLRsearch algorithm has been introduced
- for all NDR and PDR throughput tests. All tests that previously
- used binary search got converted to MLRsearch. Coverage of NDR/PDR
- tests has been extended across more test scenarios.
-
- - **2-Node Tests**: A new set of 2-node tests covering DPDK Testpmd
- and L3fwd, running on new Xeon Skylake testbeds.
-
- - **More NICs**: Increased coverage of NIC models tested: Intel-
- xxv710-da2, Intel-x710-da4.
-
- - **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.
-
-#. **Presentation and Analytics Layer**
-
- - **Performance trending**: Added continuous performance trending with
- anomaly detection and analysis for DPDK.
+#. 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`.
+
+..
+ // 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`.
+
+#. DPDK RELEASE VERSION CHANGE
+
+ - |csit-release| tested |dpdk-release|, as used by |vpp-release|.
