Release Notes
=============
@@ -6,40 +8,52 @@ Changes in |csit-release|
#. VPP PERFORMANCE TESTS
- - **Service density 2n-skx tests**: Added higher NF density tests with
- IPSec encencryption between DUTs.
+ - **Added new performance testbed 3n-snr** (3 Node SnowRidge, with Intel
+ Atom processors).
+
+ - **Added GTPU HW offload tests** using VPP GTPU hardware offload
+ with Intel e810 4p25ge NICs (3n-icx testbeds only). These tests
+ were already there in CSIT-2206, but were yielding invalid
+ results due to using TRex v2.97 that was incompatible with e810
+ NICs used for those tests.
- - **AVF tests**: Full test coveraged based on code changes in CSIT core
- layer (driver/interface awareness) and generated by suite generator
- (Fortville NICs only).
+ - **Added Wireguard tests** using VPP software crypto (3n-icx, 3n-snr
+ testbeds) and using built-in hardware crypto QAT device (3n-snr testbed
+ only).
- - **Hoststack TCP/IP tests**: Major refactor of Hoststack TCP
- performance tests using WRK generator talking to the VPP HTTP
- static server plugin measuring connections per second and
- requests per second.
+ - **Reduction of tests**: Removed certain test variations executed
+ iteratively for the report (as well as in daily and weekly
+ trending) due to physical testbeds overload.
#. TEST FRAMEWORK
- - **CSIT Python3 Support**: Full migration of CSIT from Python2.7 to
- Python3.6. This change includes library migration, PIP dependency upgrade,
- CSIT container images, infrastructure packages ugrade/installation.
+ - CSIT-2210 executes all VPP v22.10 performance tests using vpp ubuntu2204
+ images, due to CSIT execution environment change as noted below. This
+ applies to all performance testbeds except Denverton. Consequently, VPP
+ v22.06 has not been re-tested in CSIT-2210 environment, as no ubuntu204
+ images are available for that VPP version. Performance comparison
+ between VPP v22.10 (current version) vs VPP v22.06 (previous version)
+ may be impacted by VPP build environment change (ubuntu2004 to ubuntu
+ 2204) change and CSIT environment change. See :ref:`vpp_rca` for
+ details.
- - **CSIT PAPI Support**: Finished conversion of CSIT VAT L1 keywords
- to PAPI L1 KWs in CSIT using VPP Python bindings (VPP PAPI).
- Redesign of key components of PAPI Socket Executor and PAPI
- history. Due to issues with PAPI performance, VAT is still used
- in CSIT for all VPP scale tests. See known issues below.
+ - **CSIT test environment** version has been updated to ver. 11, see
+ :ref:`test_environment_versioning`.
- - **General Code Housekeeping**: Ongoing RF keywords optimizations,
- removal of redundant RF keywords and aligning of suite/test
- setup/teardowns.
+ - **TCP TPUT profiles** had to be changed, as newer TRex versions
+ are not deterministic enough when deciding when to send an ACK.
+ - **CSIT PAPI support**: Due to issues with PAPI performance, and
+ deprecation of VAT, VPP CLI is used in CSIT for many VPP scale
+ tests. See :ref:`vpp_known_issues`.
+
+ - **General Code Housekeeping**: Ongoing code optimizations and bug
+ fixes.
#. PRESENTATION AND ANALYTICS LAYER
- - **Graphs Layout Improvements**: Improved performance graphs layout
- for better readibility and maintenance: test grouping, axis
- labels, descriptions, other informative decoration.
+ - **C-Dash** `performance dashboard `_ got updated UI and
+ updated backend increasing its performance and robustness.

++----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
+| 2 | `CSIT-1785 | NAT44ED tests failing to establish all TCP sessions. |
+| | `_ | At least for max scale, in allotted time (limited by session 500s timeout) due to worse |

+| # | JiraID | Issue Description |
++====+=========================================+=========================================================================================================+
+| 1 | `CSIT-1671 | All CSIT scale tests can not use PAPI due to much slower performance compared to VAT/CLI (it takes much |
+| | `_ | longer to program VPP). This needs to be addressed on the PAPI side. |
+| +-----------------------------------------+ Currently, the time critical code uses VAT running large files with exec statements and CLI commands. |
+| | `VPP-1763 | Still, we needed to reduce the number of scale tests run to keep overall duration reasonable. |
+| | `_ | More improvements needed to achieve sufficient configuration speed. |

+Root Cause Analysis for Performance Changes

+
+List of RCAs in |csit-release| for VPP performance changes:
+
++----+-----------------------------------------+--------------------------------------------------------------------+
+| # | JiraID | Issue Description |
++====+=========================================+====================================================================+
+| 1 | `CSIT-1887 | rls2210 RCA: ASTF tests |
+| | `_ | TRex upgrade decreased TRex performance. NAT results not affected, |
+| | | except on Denverton due to interference from VPP-2010. |
++----+-----------------------------------------+--------------------------------------------------------------------+
+| 2 | `CSIT-1888 | rls2210 RCA: testbed differences, especially for ipsec |
+| | `_ | Not caused by VPP code nor CSIT code. |
+| | | Most probable cause is clang-14 behavior. |
++----+-----------------------------------------+--------------------------------------------------------------------+
+| 3 | `CSIT-1889 | rls2210 RCA: policy-outbound-nocrypto |
+| | `_ | When VPP added spd fast path matching (Gerrit 36097), |
+| | | it decreased MRR of the corresponding tests, at least on 3-alt. |
