   6 # CSIT 24.06 - VPP Performance
   7
   8 1. TEST FRAMEWORK
   9    - **CSIT test environment** version has been updated to ver. 15, see
  10      [Environment Versioning]({{< ref "../../../infrastructure/fdio_csit_testbed_versioning" >}}).
  11    - **General Code Housekeeping**: Ongoing code optimizations and bug fixes.
  12 2. VPP PERFORMANCE TESTS
  13    - Added tests:
  14      - Added memif+DMA tests; added 1518B and 4c memif testcases.
  15      - Added nginx+DMA tests; added 2048B testcases.
  16      - Added IPsec hwasync tests to 3n-icxd and 3n-snr.
  17      - Added IPsec tests to cover more encryption algorithms and other settings.
  18      - Added more SOAK tests.
  19      - Added selected 6-port tests for 3na-spr.
  20    - Edited tests:
  21      - Selected single-flow tests now use single worker even if SMT is on.
  22      - IPsecHW tests now use rxq ratio of 2.
  23        - This means one worker reads only from one of two ports.
  24        - This workaround avoids some inefficiencies,
  25        - but still does not reach the expected performance on 3nb-spr.
  26      - 1518B tests with encapsulation overhead now properly use no-multi-seg.
  27      - Added TX checksum offload to hoststack tests missing it.
  28 3. PRESENTATION AND ANALYTICS LAYER
  29    - Detailed views added to comparison tables.

  31 # Known Issues
  32
  33 These are issues that cause test failures or otherwise limit usefulness of CSIT
  34 testing.
  35
  36 ## New
  37
  38 Any issue listed here may have been present also in a previous release,
  39 but was not detected/recognized/reported enough back then.
  40 Also, issues previously thought fixed but now reopened are listed here.

  62 # Root Cause Analysis for Regressions
  63
  64 List of RCAs in CSIT 24.06 for VPP performance regressions.
  65 Not listing differences caused by known issues (uneven worker load
  66 due to randomized RSS or other per-worker issues).
  67 Also not listing tests which historically show large performance variance.
  68
  69 Contrary to issues, these genuine regressions do not limit usefulness
  70 of CSIT testing. So even if they are not fixed
  71 (e.g. when the regression is an expected consequence of added functionality),
  72 they will not be re-listed in the next release report.
