   7 #. VPP PERFORMANCE TESTS
   8
   9    - CSIT test environment is now versioned, with ver. 1 associated
  10      with CSIT rls1908 git branch as of 2019-08-21, and ver. 2
  11      associated with CSIT rls2001 and master git branches as of
  12      2020-03-27.
  13
  14    - To identify performance changes due to VPP code changes from
  15      v20.01.0 to v20.05.0, both have been tested in CSIT environment
  16      ver. 2 and compared against each other. All substantial
  17      progressions has been marked up with RCA analysis. See
  18      :ref:`vpp_compare_current_vs_previous_release` and
  19      :ref:`vpp_known_issues`.

  21 #. TEST FRAMEWORK
  22
  23    - **CSIT PAPI support**: Due to issues with PAPI performance, VAT is
  24      still used in CSIT for all VPP scale tests. See known issues below.
  25
  26    - **General Code Housekeeping**: Ongoing RF keywords optimizations,
  27      removal of redundant RF keywords and aligning of suite/test
  28      setup/teardowns.

  30 #. PRESENTATION AND ANALYTICS LAYER
  31
  32    - **Graphs layout improvements**: Improved performance graphs layout
  33      for better readibility and maintenance: test grouping, axis
  34      labels, descriptions, other informative decoration.

  50 | 1  | `CSIT-570                               | Sporadic (1 in 200) NDR discovery test failures on x520. DPDK reporting rx-errors, indicating L1 issue.   |
  51 |    | <https://jira.fd.io/browse/CSIT-570>`_  | Suspected issue with HW combination of X710-X520 in LF testbeds. Not observed outside of LF testbeds.     |
  52 +----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
  53 | 2  | `VPP-662                                | 9000B packets not supported by NICs VIC1227 and VIC1387.                                                  |

  62 | 5  | `CSIT-1591                              | All CSIT scale tests can not use PAPI due to much slower performance compared to VAT/CLI (it takes much   |
  63 |    | <https://jira.fd.io/browse/CSIT-1499>`_ | longer to program VPP). This needs to be addressed on the PAPI side.                                      |
