9 #. VPP PERFORMANCE TESTS
11 - **Enhanced and added VPP hoststack tests** to daily and weekly
12 trending including: Quic VPP Echo, UDP+TCP LD_PRELOAD iPerf3,
15 - **Added Nvidia/Mellanox DPDK tests** to daily and weekly trending
16 and report, in addition to RDMA_CORE ones that were already
19 - **Jumbo frames tests** got fixed and re-added number of to report
22 - **Intel Xeon SKX performance testbeds** got decommissioned and
23 removed from FD.io performance lab.
27 - **CSIT test environment** version has not changed from ver. 11 used
28 in previous release, see :ref:`test_environment_versioning`.
30 - **CSIT PAPI optimizations for scale** got applied improving PAPI

151 | # | JiraID | Issue Description |
152 +====+=========================================+====================================================================+
153 | 1 | `CSIT-1887 | rls2210 RCA: ASTF tests |
154 | | <https://jira.fd.io/browse/CSIT-1887>`_ | TRex upgrade decreased TRex performance. NAT results not affected, |
155 | | | except on Denverton due to interference from VPP-2010. |

158 | | <https://jira.fd.io/browse/CSIT-1888>`_ | Not caused by VPP code nor CSIT code. |
159 | | | Most probable cause is clang-14 behavior. |

162 | | <https://jira.fd.io/browse/CSIT-1889>`_ | When VPP added spd fast path matching (Gerrit 36097), |
