Release Notes
=============
Changes in |csit-release|
-------------------------
#. VPP PERFORMANCE TESTS
- **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.
- **Added Wireguard tests** using VPP software crypto (3n-icx, 3n-snr
testbeds) and using built-in hardware crypto QAT device (3n-snr testbed
only).
- **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-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 test environment** version has been updated to ver. 11, see
:ref:`test_environment_versioning`.
- **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
- **C-Dash** `performance dashboard <http://csit.fd.io/>`_ got updated UI and
updated backend increasing its performance and robustness.

| # | JiraID | Issue Description |
+====+=========================================+===========================================================================================================+
| 1 | `CSIT-1782 | Multicore AVF tests are failing when trying to create interface. |
| | <https://jira.fd.io/browse/CSIT-1782>`_ | Frequency is reduced by CSIT workaround, but occasional failures do still happen. |
+----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
| 2 | `CSIT-1785 | NAT44ED tests failing to establish all TCP sessions. |
| | <https://jira.fd.io/browse/CSIT-1785>`_ | At least for max scale, in allotted time (limited by session 500s timeout) due to worse |
| +-----------------------------------------+ slow path performance than previously measured and calibrated for. |
| | `VPP-1972 | CSIT removed the max scale NAT tests to avoid this issue. |
| | <https://jira.fd.io/browse/VPP-1972>`_ | |
+----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
| 3 | `CSIT-1799 | All NAT44-ED 16M sessions CPS scale tests fail while setting NAT44 address range. |

+----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
| 5 | `CSIT-1801 | 9000B payload frames not forwarded over tunnels due to violating supported Max Frame Size (VxLAN, LISP, |
| | <https://jira.fd.io/browse/CSIT-1801>`_ | SRv6). |

+----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
| 8 | `CSIT-1808 | All tests with 9000B payload frames not forwarded over memif interfaces. |
| | <https://jira.fd.io/browse/CSIT-1808>`_ | |
+----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
| 9 | `CSIT-1827 | 3n-icx, 3n-skx: all AVF crypto tests sporadically fail. 1518B with no traffic, IMIX with excessive |
| | <https://jira.fd.io/browse/CSIT-1827>`_ | packet loss. |

Fixed
_____
Issues reported in previous releases which were fixed in this release:
+----+-----------------------------------------+---------------------------------------------------------------------------------------------------------+
| # | 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 |
| | <https://jira.fd.io/browse/CSIT-1671>`_ | 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. |
| | <https://jira.fd.io/browse/VPP-1763>`_ | 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 |
| | <https://jira.fd.io/browse/CSIT-1887>`_ | 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 |
| | <https://jira.fd.io/browse/CSIT-1888>`_ | Not caused by VPP code nor CSIT code. |
| | | Most probable cause is clang-14 behavior. |
+----+-----------------------------------------+--------------------------------------------------------------------+
| 3 | `CSIT-1889 | rls2210 RCA: policy-outbound-nocrypto |
| | <https://jira.fd.io/browse/CSIT-1889>`_ | When VPP added spd fast path matching (Gerrit 36097), |
| | | it decreased MRR of the corresponding tests, at least on 3-alt. |
