#. 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), to later replace 3n-dnv and 2n-dnv (3 and 2 Node
+ Denverton) testbeds.
+
+ - **Added GTPU HW offload tests** for Intel e810 4p25ge NICs on 2n-icx
+ testbeds.
+
+ - **Added Wireguard tests** for VPP software path (3n-icx, 3n-snr
+ testbeds) and with built-in HW 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
#. TEST FRAMEWORK
- - **CSIT test environment** version has been updated to ver. 9, see
+ - **CSIT test environment** version has been updated to ver. 11, see
:ref:`test_environment_versioning`.
+ - **TCP tput profiles** have 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.

| | <https://jira.fd.io/browse/CSIT-1671>`_ | longer to program VPP). This needs to be addressed on the PAPI side. |
| +-----------------------------------------+ 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. |
