-Release Notes
-=============
-
-Changes in |csit-release|
--------------------------
-
-#. VPP PERFORMANCE TESTS
-
- - **Intel Xeon Ice Lake**: Performance test data for these platforms
- continues to be provided by external Intel benchmarking labs
- executing |csit-release| tests. For details about the physical
- setup see :ref:`tested_physical_topologies`.
-
- - **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, CLI is used in CSIT for many VPP scale tests.
- See known issues below.
-
- - **General Code Housekeeping**: Ongoing code optimizations and bug
- fixes.
-
-#. PRESENTATION AND ANALYTICS LAYER
-
- - **Graphs improvements**: Updated Packet Latency graphs,
- see :ref:`latency_methodology`.

-| # | JiraID | Issue Description |
-+====+=========================================+===========================================================================================================+
-| 1 | `CSIT-1789 | AVF driver does not perform RSS in a deterministic way. |
-| | <https://jira.fd.io/browse/CSIT-1789>`_ | VPP now uses the same RSS key with AVF driver as with DPDK driver. |
-+----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
-| 2 | `CSIT-1786 | IP4 and IP6 scale tests failing with no traffic forwarded. |
-| | <https://jira.fd.io/browse/CSIT-1786>`_ | CSIT replaced the old single VAT command by file full of "exec" CLI commands executed by VAT. |

-| # | JiraID | Issue Description |
-+====+=========================================+===========================================================================================================+
-| 3 | `CSIT-1782 | Multicore AVF tests are failing when trying to create interface. |
-| | <https://jira.fd.io/browse/CSIT-1782>`_ | Frequency is reduced by s 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. |
-| +-----------------------------------------+ |
-| 5 | `VPP-1998 | |
-| | <https://jira.fd.io/browse/VPP-1998>`_ | |
-+----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
-| 6 | `CSIT-1785 | NAT44ED tests failing to establish all TCP sessions. |
-| | <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. |
-| | <https://jira.fd.io/browse/VPP-1972>`_ | |
-+----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
-| 7 | `CSIT-1791 | Performance regression in RDMA tests, due to CSIT environment changes. |
-| | <https://jira.fd.io/browse/CSIT-1791>`_ | Two symptoms: 1. 10-20% regression across most tests. 2. DUT performance cap just below 38 Mpps. |
