#. 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`.
-
- - **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.
#. TEST FRAMEWORK
+ - **Removed ASTF PPS tests**: They provide no real benefit
+ compared to TPUT tests. The ip4base variants renamed to TPUT.
+
+ - **Changed TCP TPUT profiles**: The previous ones were found to be faulty.
+ The new ones do not use bursts of packets to avoid CSIT-1830 and CSIT-1846.
+
- **CSIT test environment** version has been updated to ver. 10, see
:ref:`test_environment_versioning`.
