#. 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`.
+ - **Added new performance testbed 3n-snr** (3 Node SnowRidge, with Intel
+ Atom processors).
+
+ - **Added GTPU HW offload tests** using VPP GTPU hardware offload
+ with Intel e810 4p25ge NICs (3n-icx testbeds only). These tests
+ were already there in CSIT-2206, but were yielding invalid
+ results due to using TRex v2.97 that was incompatible with e810
+ NICs used for those tests.
+
+ - **Added Wireguard tests** using VPP software crypto (3n-icx, 3n-snr
+ testbeds) and using built-in hardware crypto QAT device (3n-snr testbed
+ only).
- **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.
- - **RC2 coverage test data is used for 2n-icx test bed**: There is only
- one 2n-icx test bed and the amount of tests is large (same as 2n-skx with 4
- test beds), so we decided to use test data already available from RC2
- testing.
-
#. TEST FRAMEWORK
- - **CSIT test environment** version has been updated to ver. 10, see
+ - CSIT-2210 executes all VPP v22.10 performance tests using vpp ubuntu2204
+ images, due to CSIT execution environment change as noted below. This
+ applies to all performance testbeds except Denverton. Consequently, VPP
+ v22.06 has not been re-tested in CSIT-2210 environment, as no ubuntu204
+ images are available for that VPP version. Performance comparison
+ between VPP v22.10 (current version) vs VPP v22.06 (previous version)
+ may be impacted by VPP build environment change (ubuntu2004 to ubuntu
+ 2204) change and CSIT environment change. See :ref:`vpp_rca` for
+ details.
+
+ - **CSIT test environment** version has been updated to ver. 11, see
:ref:`test_environment_versioning`.
+ - **TCP TPUT profiles** had to be changed, as newer TRex versions
+ are not deterministic enough when deciding when to send an ACK.
+
- **CSIT PAPI support**: Due to issues with PAPI performance, and
deprecation of VAT, VPP CLI is used in CSIT for many VPP scale
tests. See :ref:`vpp_known_issues`.
#. PRESENTATION AND ANALYTICS LAYER
- - **Graphs improvements**: Updated Packet Latency graphs,
- see :ref:`latency_methodology`.
+ - **C-Dash** `performance dashboard <http://csit.fd.io/>`_ got updated UI and
+ updated backend increasing its performance and robustness.

+----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
-| 2 | `CSIT-1671 | All CSIT scale tests can not use PAPI due to much slower performance compared to VAT/CLI (it takes much |

-| +-----------------------------------------+ 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. |
