- - CSIT test environment is versioned, see
- :ref:`test_environment_versioning`.
-
- - **GENEVE tests**: Added VPP performance tests for GENEVE tunnels.
-
- - See :ref:`geneve_methodology` for more details.
-
- - **NAT44 tests**: Added new test type, pure throughput tests.
- They are similar to PPS tests, but they employ ramp-up trials
- to ensure all sessions are created (and not timing out)
- for performance trials.
-
- - **Jumbo for ipsec**: Test cases with 9000 byte frames are re-enabled
- in ipsec suites.
-
- - **Randomized profiles**: Improved repeatability and cycle length.
- For details, see :ref:`packet_flow_ordering`.
-
- - **Arm 2n-tx2 testbed**: New physical testbed type installed in
- FD.io CSIT, with VPP and DPDK performance data added to CSIT
- trending and this report.
-
- - **Framework speedup**: Shortened overall test job duration
- by using a different test selection mechanism (using --test
- instead of --include) and by avoiding unnecessary PAPI reconnects.
+ - **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`.
+
+ - **Arm Ampere Altra**: 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_3n_alt`.
+
+ - **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.
