-To identify performance changes due to TRex code development between previous
-and current TRex version, both have been tested in CSIT environment of latest
-version and compared against each other. All substantial progressions and
-regressions have been marked up with RCA analysis. See :ref:`trex_known_issues`.
-
-Physical Testbeds
------------------
-
-FD.io CSIT performance tests are executed in physical testbeds hosted by
-:abbr:`LF (Linux Foundation)` for FD.io project. Physical testbed
-topology used:
-
-- **1-Node Topology**: Consisting of TG with 1 NIC with 2 ports connected
- together - loopback connection.
List of RCAs in |csit-release| for VPP performance changes:
-+----+-----------------------------------------+-------------------------------------------------------------------------------------+
-| # | JiraID | Issue Description |
-+====+=========================================+=====================================================================================+
-| 1 | `VPP-2030 | regression: ip6base on ICX around 2022-03-23 |
-| | <https://jira.fd.io/browse/VPP-2030>`_ | "Loads blocked due to overlapping with a preceding store that cannot be forwarded." |
-| | | started happening in ip6-lookup graph node. |
-+----+-----------------------------------------+-------------------------------------------------------------------------------------+
-| 2 | `CSIT-1852 | 2n-zn2 mellanox performance cap |
-| | <https://jira.fd.io/browse/CSIT-1852>`_ | Old issue, only now distinguished from CSIT-1751. |
-| | | This testbed+nic combination is capped below 28 Mpps, cause not identified yet. |
-+----+-----------------------------------------+-------------------------------------------------------------------------------------+
-| 3 | `CSIT-1853 | trending regression: nat44ed cps around 2202-04-01 |
-| | <https://jira.fd.io/browse/CSIT-1853>`_ | VPP change added more computation to slow path (in order to support multiple VRFs). |
-| | | Not clear if the VPP implementation is optimized enough. |

+| 1 | `CSIT-1887 | rls2210 RCA: ASTF tests |
+| | <https://jira.fd.io/browse/CSIT-1887>`_ | TRex upgrade decreased TRex performance. NAT results not affected, |
+| | | except on Denverton due to interference from VPP-2010. |

+| 2 | `CSIT-1888 | rls2210 RCA: testbed differences, especially for ipsec |
+| | <https://jira.fd.io/browse/CSIT-1888>`_ | Not caused by VPP code nor CSIT code. |
+| | | Most probable cause is clang-14 behavior. |
