Release Notes
=============
#. VPP PERFORMANCE TESTS
- - CSIT test environment is versioned, see
- :ref:`test_environment_versioning`.
+ - **Intel Xeon Ice Lake**: Performance test data for these platforms
+ continues to be provided by external Intel benchmarking labs
+ executing |csit-release| tests. For details about the physical
+ setup see :ref:`tested_physical_topologies`.
+
+ - **AWS EC2 c5n**: Performance test data for AWS c5n instances has
+ been added to report for ip4, ip6 and ipsec tests.
- - To identify performance changes due to VPP code changes from
- v20.01.0 to v20.05.0, both have been tested in CSIT environment
- ver. 4 and compared against each other. All substantial
- progressions has been marked up with RCA analysis. See
- :ref:`vpp_compare_current_vs_previous_release` and
- :ref:`vpp_known_issues`.
+ - **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
- - **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 test environment** version has been updated to ver. 8, see
+ :ref:`test_environment_versioning`.
+
+ - **CSIT in AWS environment**: Completed CSIT automation support for
+ AWS c5n instances environment, including weekly performance
+ trending tests execution.
- - **General Code Housekeeping**: Ongoing RF keywords optimizations,
- removal of redundant RF keywords and aligning of suite/test
- setup/teardowns.
+ - **CSIT PAPI support**: Due to issues with PAPI performance, and
+ deprecation of VAT, CLI is used in CSIT for many VPP scale tests.
+ See known issues below.
+
+ - **General Code Housekeeping**: Ongoing code optimizations and bug
+ fixes.
#. PRESENTATION AND ANALYTICS LAYER
- - **Graphs layout improvements**: Improved performance graphs layout
- for better readibility and maintenance: test grouping, axis
- labels, descriptions, other informative decoration.
+ - **Graphs improvements**: Updated Packet Latency graphs,
+ see :ref:`latency_methodology`.

| # | JiraID | Issue Description |
+====+=========================================+===========================================================================================================+
-| 1 | `CSIT-570 | Sporadic (1 in 200) NDR discovery test failures on x520. DPDK reporting rx-errors, indicating L1 issue. |
-| | <https://jira.fd.io/browse/CSIT-570>`_ | Suspected issue with HW combination of X710-X520 in LF testbeds. Not observed outside of LF testbeds. |
+| 1 | `CSIT-1782 | Multicore AVF tests are failing when trying to create interface. The issue persists after FVL FW upgrade. |
+| | <https://jira.fd.io/browse/CSIT-1782>`_ | |
++----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
+| 2 | `CSIT-1763 | Adapt ramp-up phase of nat44 tests for different frame sizes. |
+| | <https://jira.fd.io/browse/CSIT-1763>`_ | Currently ramp-up phase rate and duration values are correctly set for tests with 64B frame size. |
+----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
-| 2 | `VPP-662 | 9000B packets not supported by NICs VIC1227 and VIC1387. |
-| | <https://jira.fd.io/browse/VPP-662>`_ | |
+| 3 | `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. |
+| +-----------------------------------------+ 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 |
+| | <https://jira.fd.io/browse/VPP-1763>`_ | too long. |
+----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
-| 3 | `VPP-1677 | 9000B ip4 nat44: VPP crash + coredump. |
-| | <https://jira.fd.io/browse/VPP-1677>`_ | VPP crashes very often in case that NAT44 is configured and it has to process IP4 jumbo frames (9000B). |
+| 4 | `CSIT-1789 | AVF driver does not perform RSS in a deterministic way. |
+| | <https://jira.fd.io/browse/CSIT-1789>`_ | This increases standard deviation of tests with small number of flows (mainly ipsec). |
+----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
-| 4 | `CSIT-1591 | 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-1499>`_ | longer to program VPP). This needs to be addressed on the PAPI side. |
-| +-----------------------------------------+ |
-| | `VPP-1763 | |
-| | <https://jira.fd.io/browse/VPP-1763>`_ | |
+| 5 | `CSIT-1780 | IPSEC SW async scheduler MRR tests failing with no traffic forwarded. |
+| | <https://jira.fd.io/browse/CSIT-1780>`_ | |
+----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
-| 5 | `VPP-1675 | IPv4 IPSEC 9000B packet tests are failing as no packet is forwarded. |
-| | <https://jira.fd.io/browse/VPP-1675>`_ | Reason: chained buffers are not supported. |
+| 6 | `CSIT-1786 | IP4 and IP6 scale tests failing with no traffic forwarded. |
+| | <https://jira.fd.io/browse/CSIT-1786>`_ | Issue reported to VPP devs. |
+----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
-| 6 | `CSIT-1593 | IPv4 AVF 9000B packet tests are failing on 3n-skx while passing on 2n-skx. |
-| | <https://jira.fd.io/browse/CSIT-1593>`_ | |
+| 7 | `CSIT-1785 | NAT44ED tests failing to establish all TCP sessions. |
+| | <https://jira.fd.io/browse/CSIT-1785>`_ | |
+----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
-| 7 | `CSIT-1679 | 2n-clx VPP ip4 tests with xxv710 and avf driver are sporadically failing. |
-| | <https://jira.fd.io/browse/CSIT-1679>`_ | |
+| 8 | `CSIT-1791 | Performance regression in RDMA tests, due to CSIT environment changes. |
+| | <https://jira.fd.io/browse/CSIT-1791>`_ | |
+----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
