   9 #. VPP PERFORMANCE TESTS
  10
  11    - **Intel Xeon Ice Lake**: Performance test data for these platforms
  12      continues to be provided by external Intel benchmarking labs
  13      executing |csit-release| tests. For details about the physical
  14      setup see :ref:`tested_physical_topologies`.
  15
  16    - **AWS EC2 c5n**: Performance test data for AWS c5n instances has
  17      been added to report for ip4, ip6 and ipsec tests.
  18
  19    - **Reduction of tests**: Removed certain test variations executed
  20      iteratively for the report (as well as in daily and weekly
  21      trending) due to physical testbeds overload.
  22
  23 #. TEST FRAMEWORK
  24
  25    - **CSIT test environment** version has been updated to ver. 8, see
  26      :ref:`test_environment_versioning`.
  27
  28    - **CSIT in AWS environment**: Completed CSIT automation support for
  29      AWS c5n instances environment, including weekly performance
  30      trending tests execution.
  31
  32    - **CSIT PAPI support**: Due to issues with PAPI performance, and
  33      deprecation of VAT, CLI is used in CSIT for many VPP scale tests.
  34      See known issues below.
  35
  36    - **General Code Housekeeping**: Ongoing code optimizations and bug
  37      fixes.
  38
  39 #. PRESENTATION AND ANALYTICS LAYER
  40
  41    - **Graphs improvements**: Updated Packet Latency graphs,
  42      see :ref:`latency_methodology`.

  53 List of known issues in |csit-release| for VPP performance tests:

  55 +----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
  56 | #  | JiraID                                  | Issue Description                                                                                         |
  57 +====+=========================================+===========================================================================================================+
  58 |  1 | `CSIT-1782                              | Multicore AVF tests are failing when trying to create interface. The issue persists after FVL FW upgrade. |
  59 |    | <https://jira.fd.io/browse/CSIT-1782>`_ |                                                                                                           |
  60 +----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
  61 |  2 | `CSIT-1763                              | Adapt ramp-up phase of nat44 tests for different frame sizes.                                             |
  62 |    | <https://jira.fd.io/browse/CSIT-1763>`_ | Currently ramp-up phase rate and duration values are correctly set for tests with 64B frame size.         |
  63 +----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
  64 |  3 | `CSIT-1671                              | All CSIT scale tests can not use PAPI due to much slower performance compared to VAT/CLI (it takes much   |
  65 |    | <https://jira.fd.io/browse/CSIT-1671>`_ | longer to program VPP). This needs to be addressed on the PAPI side.                                      |
  66 |    +-----------------------------------------+ The usual PAPI library spends too much time parsing arguments, so even with async processing (hundreds of |
  67 |    | `VPP-1763                               | commands in flight over socket), the VPP configuration for large scale tests (millions of messages) takes |
  68 |    | <https://jira.fd.io/browse/VPP-1763>`_  | too long.                                                                                                 |
  69 +----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
  70 |  4 | `CSIT-1789                              | AVF driver does not perform RSS in a deterministic way.                                                   |
  71 |    | <https://jira.fd.io/browse/CSIT-1789>`_ | This increases standard deviation of tests with small number of flows (mainly ipsec).                     |
  72 +----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
  73 |  5 | `CSIT-1780                              | IPSEC SW async scheduler MRR tests failing with no traffic forwarded.                                     |
  74 |    | <https://jira.fd.io/browse/CSIT-1780>`_ |                                                                                                           |
  75 +----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
  76 |  6 | `CSIT-1786                              | IP4 and IP6 scale tests failing with no traffic forwarded.                                                |
  77 |    | <https://jira.fd.io/browse/CSIT-1786>`_ | Issue reported to VPP devs.                                                                               |
  78 +----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
  79 |  7 | `CSIT-1785                              | NAT44ED tests failing to establish all TCP sessions.                                                      |
  80 |    | <https://jira.fd.io/browse/CSIT-1785>`_ |                                                                                                           |
  81 +----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
  82 |  8 | `CSIT-1791                              | Performance regression in RDMA tests, due to CSIT environment changes.                                    |
  83 |    | <https://jira.fd.io/browse/CSIT-1791>`_ |                                                                                                           |

  94 |  1 | `VPP-1972                               | One VPP change has decreased performance of NAT44ed processing, mostly slow path.                         |
