   5 -------------------------
   6
   7 #. VPP PERFORMANCE TESTS
   8
   9    - CSIT test environment is versioned, see
  10      :ref:`test_environment_versioning`.
  11
  12    - To identify performance changes due to VPP code changes from
  13      v20.01.0 to v20.05.0, both have been tested in CSIT environment
  14      ver. 4 and compared against each other. All substantial
  15      progressions has been marked up with RCA analysis. See
  16      :ref:`vpp_compare_current_vs_previous_release` and
  17      :ref:`vpp_known_issues`.
  18
  19 #. TEST FRAMEWORK
  20
  21    - **CSIT PAPI support**: Due to issues with PAPI performance, VAT is
  22      still used in CSIT for all VPP scale tests. See known issues below.
  23
  24    - **General Code Housekeeping**: Ongoing RF keywords optimizations,
  25      removal of redundant RF keywords and aligning of suite/test
  26      setup/teardowns.
  27
  28 #. PRESENTATION AND ANALYTICS LAYER
  29
  30    - **Graphs layout improvements**: Improved performance graphs layout
  31      for better readibility and maintenance: test grouping, axis
  32      labels, descriptions, other informative decoration.

  57 |  4 | `CSIT-1591                              | All CSIT scale tests can not use PAPI due to much slower performance compared to VAT/CLI (it takes much   |
  58 |    | <https://jira.fd.io/browse/CSIT-1499>`_ | longer to program VPP). This needs to be addressed on the PAPI side.                                      |
