+Release Notes
+=============
+
+Changes in |csit-release|
+-------------------------
+
+#. VPP PERFORMANCE TESTS
+
+ - **Regressions with DPDK drivers**: Change from DPDK v21.08 to DPDK
+ v21.11 introduced regression across all tests using dpdk
+ drivers (with dpdk_plugin loaded). Compared to previous VPP
+ release performance drop varies in the range of -15% to -6%,
+ depending on test. It is related to updated MTU checks within
+ DPDK code and associated VPP code changes. See
+ `VPP v2202 release notes <https://s3-docs.fd.io/vpp/22.02/aboutvpp/releasenotes/v22.02.html>`_
+ and :ref:`vpp_known_issues`.
+
+ - **Number of CSIT 9000B frame tests failing**: tests with higher
+ encapsulation overhead are failing due to exceeding default
+ Ethernet Maximum Frame Size value that has been reduced by MTU
+ related VPP code changes. See
+ `VPP v2202 release notes <https://s3-docs.fd.io/vpp/22.02/aboutvpp/releasenotes/v22.02.html>`_
+ and :ref:`vpp_known_issues`.
+
+ - **Intel Xeon Ice Lake**: Performance test data for these platforms
+ is now provided by testbeds newly installed in FD.io CSIT labs.
+ For details about the physical setup see
+ :ref:`physical_testbeds_2n_icx` and
+ :ref:`physical_testbeds_3n_icx`.
+
+ - **Reduction of tests**: Removed certain test variations executed
+ iteratively for the report (as well as in daily and weekly
+ trending) due to physical testbeds overload.
+
+#. TEST FRAMEWORK
+
+ - **CSIT test environment** version has been updated to ver. 9, see
+ :ref:`test_environment_versioning`.
+
+ - **CSIT PAPI support**: Due to issues with PAPI performance, and
+ deprecation of VAT, VPP CLI is used in CSIT for many VPP scale
+ tests. See :ref:`vpp_known_issues`.
+
+ - **General Code Housekeeping**: Ongoing code optimizations and bug
+ fixes.
+
+#. PRESENTATION AND ANALYTICS LAYER
+
+ - **Graphs improvements**: Updated Packet Latency graphs,
+ see :ref:`latency_methodology`.

++====+=========================================+===========================================================================================================+
+| 3 | `CSIT-1782 | Multicore AVF tests are failing when trying to create interface. |
+| | <https://jira.fd.io/browse/CSIT-1782>`_ | Frequency is reduced by CSIT workaround, but occasional failures do still happen. |
++----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
+| 4 | `CSIT-1671 | All CSIT scale tests can not use PAPI due to much slower performance compared to VAT/CLI (it takes much |
+| | <https://jira.fd.io/browse/CSIT-1671>`_ | longer to program VPP). This needs to be addressed on the PAPI side. |
+| +-----------------------------------------+ Currently, the time critical code uses VAT running large files with exec statements and CLI commands. |
+| | `VPP-1763 | Still, we needed to reduce the number of scale tests run to keep overall duration reasonable. |
+| | <https://jira.fd.io/browse/VPP-1763>`_ | More improvements needed to achieve sufficient configuration speed. |
++----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
+| 5 | `CSIT-1789 | IPSEC SW async scheduler tests show bad behavior. |
+| | <https://jira.fd.io/browse/CSIT-1789>`_ | VPP code is not behaving correctly when crypto workers are the bottleneck. |

+| | <https://jira.fd.io/browse/CSIT-1785>`_ | At least for max scale, in allotted time (limited by session 500s timeout) due to worse |
+| +-----------------------------------------+ slow path performance than previously measured and calibrated for. |
+| | `VPP-1972 | CSIT removed the max scale NAT tests to avoid this issue. |
