-Performance Improvements\r
-------------------------\r
-\r
-Substantial improvements in measured packet throughput have been observed in a\r
-number of CSIT |release| tests listed below, with relative increase of\r
-double-digit percentage points. Relative improvements for this release are\r
-calculated against the test results listed in CSIT |release-1| report. The\r
-comparison is calculated between the mean values based on collected and\r
-archived test results' samples for involved VPP releases. Standard deviation\r
-has been also listed for CSIT |release|. VPP-16.09 and VPP-17.01 numbers are\r
-provided for reference.\r

+Release Notes
+=============
+
+Changes in |csit-release|
+-------------------------
+
+#. VPP PERFORMANCE TESTS
+
+ - CSIT test environment is now versioned, with ver. 1 associated
+ with CSIT rls1908 git branch as of 2019-08-21, and ver. 2
+ associated with CSIT rls2001 and master git branches as of
+ 2020-03-27.
+
+ - To identify performance changes due to VPP code changes from
+ v20.01.0 to v20.05.0, both have been tested in CSIT environment
+ ver. 2 and compared against each other. All substantial
+ progressions has been marked up with RCA analysis. See
+ :ref:`vpp_compare_current_vs_previous_release` and
+ :ref:`vpp_known_issues`.
+
+#. TEST FRAMEWORK
+
+ - **CSIT PAPI support**: Due to issues with PAPI performance, VAT is
+ still used in CSIT for all VPP scale tests. See known issues below.
+
+ - **General Code Housekeeping**: Ongoing RF keywords optimizations,
+ removal of redundant RF keywords and aligning of suite/test
+ setup/teardowns.
+
+#. PRESENTATION AND ANALYTICS LAYER
+
+ - **Graphs layout improvements**: Improved performance graphs layout
+ for better readibility and maintenance: test grouping, axis
+ labels, descriptions, other informative decoration.

+| # | JiraID | Issue Description |
++====+=========================================+===========================================================================================================+
+| 1 | `CSIT-570 | Sporadic (1 in 200) NDR discovery test failures on x520. DPDK reporting rx-errors, indicating L1 issue. |
+| | <https://jira.fd.io/browse/CSIT-570>`_ | Suspected issue with HW combination of X710-X520 in LF testbeds. Not observed outside of LF testbeds. |
++----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
+| 2 | `VPP-662 | 9000B packets not supported by NICs VIC1227 and VIC1387. |
+| | <https://jira.fd.io/browse/VPP-662>`_ | |
++----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
+| 3 | `CSIT-1498 | Memif tests are sporadically failing on initialization of memif connection. |
