#. VPP PERFORMANCE TESTS
- - CSIT test environment is versioned, see
- :ref:`test_environment_versioning`.
+ - **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.
- - **Upgrade to Ubuntu 20.04 LTS**: Reinstall base operating system to
- Ubuntu 20.04.2 LTS. Upgrade includes also baseline Docker
- containers used for spawning topology.
+ - **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.
- - Initial test data for Intel Xeon Ice Lake platforms. Current
- CSIT-2106 report data for Intel Xeon Ice Lake comes from an
- external source (Intel labs running CSIT code on 8360Y D Stepping
- and 6338N processors). For detail about the physical setup
- see :ref:`tested_physical_topologies`. Tested VPP and CSIT
- versions are pre-release, VPP 21.06-rc0~779-gd640ae52f.
+ - **Added Wireguard tests** using VPP software crypto (3n-icx, 3n-snr
+ testbeds) and using built-in hardware crypto QAT device (3n-snr testbed
+ only).
- - **AF_XDP**: Added af_xdp driver testing for all testcases.
+ - **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.
- - **GTPU tunnel**: Added GTPU HW Offload IPv4 routing tests.
+#. TEST FRAMEWORK
- - **Telemetry retouch**: Redesign telemetry retrieval from DUT.
- Include VPP perfmon plugin telemetry.
+ - 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`.
-#. TEST FRAMEWORK
+ - **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, VAT is
- still used in CSIT for all VPP scale tests. See known issues below.
+ - **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`.
- - **General Code Housekeeping**: Ongoing code optimizations,
- speed ups and bug fixes.
+ - **General Code Housekeeping**: Ongoing code optimizations and bug
+ fixes.
#. 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.

-| 3 | `CSIT-1671 | All CSIT scale tests can not use PAPI due to much slower performance compared to VAT/CLI (it takes much |

-| +-----------------------------------------+ The usual PAPI library spends too much time parsing arguments, so even with async processing (hundreds of |
-| | `VPP-1763 | commands in flight over socket), the VPP configuration for large scale tests (millions of messages) takes |

+====+=========================================+===========================================================================================================+
-| 1 | `VPP-1972 | One VPP change has decreased performance of NAT44ed processing, both slow path and fast path. |
+| 1 | `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. |
+| | <https://jira.fd.io/browse/VPP-1763>`_ | More improvements needed to achieve sufficient configuration speed. |
++----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
+| 2 | `CSIT-1782 | Multicore AVF tests are failing when trying to create interface. |
+| | <https://jira.fd.io/browse/CSIT-1782>`_ | Frequency is reduced by CSIT workaround, but occasional failures do still happen. |
++----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
+| 3 | `CSIT-1785 | NAT44ED tests failing to establish all TCP sessions. |
+| | <https://jira.fd.io/browse/CSIT-1785>`_ | At least for max scale, in allotted time (limited by session 500s timeout) due to worse |
+| +-----------------------------------------+ slow path performance than previously measured and calibrated for. |
+| | `VPP-1972 | CSIT removed the max scale NAT tests to avoid this issue. |
