#. 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`.
-
- - **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.
+ - **Enhanced and added VPP hoststack tests** to daily and weekly
+ trending including: Quic VPP Echo, UDP+TCP LD_PRELOAD iPerf3,
+ LD_PRELOAD NGINX.
+
+ - **Added Nvidia/Mellanox DPDK tests** to daily and weekly trending
+ and report, in addition to RDMA_CORE ones that were already
+ there.
+
+ - **Jumbo frames tests** got fixed and re-added number of to report
+ coverage tests.
+
+ - **Intel Xeon SKX performance testbeds** got decommissioned and
+ removed from FD.io performance lab.
#. TEST FRAMEWORK
- - **CSIT test environment** version has been updated to ver. 10, see
- :ref:`test_environment_versioning`.
+ - **CSIT test environment** version has not changed from ver. 11 used
+ in previous release, see :ref:`test_environment_versioning`.
- - **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`.
+ - **CSIT PAPI optimizations for scale** got applied improving PAPI
+ programming speed especially for large scale tests. VAT has been
+ now completely deprecated from CSIT.
- **General Code Housekeeping**: Ongoing code optimizations and bug
fixes.
#. PRESENTATION AND ANALYTICS LAYER
- - **Graphs improvements**: Updated Packet Latency graphs,
- see :ref:`latency_methodology`.
+ - `Performance dashboard <http://csit.fd.io/>`_ got updated with
+ addition of VPP telemetry trending across all VPP tests. A number
+ of code and AWS resource usage optimizations got applied to the
+ data processing pipeline and UI frontend and backend.
+

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