   6 Changes in |csit-release|
   7 -------------------------
   8
   9 #. VPP PERFORMANCE TESTS
  10
  11    - **Added new performance testbed 3n-snr** (3 Node SnowRidge, with Intel
  12      Atom processors).
  13
  14    - **Added GTPU HW offload tests** using VPP GTPU hardware offload
  15      with Intel e810 4p25ge NICs (3n-icx testbeds only). These tests
  16      were already there in CSIT-2206, but were yielding invalid
  17      results due to using TRex v2.97 that was incompatible with e810
  18      NICs used for those tests.
  19
  20    - **Added Wireguard tests** using VPP software crypto (3n-icx, 3n-snr
  21      testbeds) and using built-in hardware crypto QAT device (3n-snr testbed
  22      only).
  23
  24    - **Reduction of tests**: Removed certain test variations executed
  25      iteratively for the report (as well as in daily and weekly
  26      trending) due to physical testbeds overload.
  27
  28 #. TEST FRAMEWORK
  29
  30    - CSIT-2210 executes all VPP v22.10 performance tests using vpp ubuntu2204
  31      images, due to CSIT execution environment change as noted below. This
  32      applies to all performance testbeds except Denverton. Consequently, VPP
  33      v22.06 has not been re-tested in CSIT-2210 environment, as no ubuntu204
  34      images are available for that VPP version. Performance comparison
  35      between VPP v22.10 (current version) vs VPP v22.06 (previous version)
  36      may be impacted by VPP build environment change (ubuntu2004 to ubuntu
  37      2204) change and CSIT environment change. See :ref:`vpp_rca` for
  38      details.
  39
  40    - **CSIT test environment** version has been updated to ver. 11, see
  41      :ref:`test_environment_versioning`.
  42
  43    - **TCP TPUT profiles** had to be changed, as newer TRex versions
  44      are not deterministic enough when deciding when to send an ACK.
  45
  46    - **CSIT PAPI support**: Due to issues with PAPI performance, and
  47      deprecation of VAT, VPP CLI is used in CSIT for many VPP scale
  48      tests. See :ref:`vpp_known_issues`.
  49
  50    - **General Code Housekeeping**: Ongoing code optimizations and bug
  51      fixes.
  52
  53 #. PRESENTATION AND ANALYTICS LAYER
  54
  55    - **C-Dash** `performance dashboard <http://csit.fd.io/>`_ got updated UI and
  56      updated backend increasing its performance and robustness.
