Release Notes
=============
#. VPP PERFORMANCE TESTS
- - **Service density 2n-skx tests**: Added higher density tests with dtc=0.5
- (2 NF each with 1 DT per physical core) with VPP as a VNF payload.
+ - **Added new performance testbed 3n-snr** (3 Node SnowRidge, with Intel
+ Atom processors).
- - **Experimental Soak Tests**: Added performamce soak tests framework
- code for extended time duration tests and throughput discovery
- at given PLR and at give total test time e.g. minutes, hours,
- days, weeks, months, years. See updated
- :ref:`test_methodology` section for more details.
+ - **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.
-#. TEST FRAMEWORK
+ - **Added Wireguard tests** using VPP software crypto (3n-icx, 3n-snr
+ testbeds) and using built-in hardware crypto QAT device (3n-snr testbed
+ only).
- - **Qemu code refactor**: Complete code refactor of the key components
- QemuUtil.py and QemuManager.py (L1 and L2 KW counterparts). Added
- implementation of kernel-image-kvm based VM alongisde the previously used
- NestedVM images. Added ability to run VPP as a payload in VNF.
+ - **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.
- - **CSIT PAPI Support**: Continue converting existing VAT L1 keywords to
- PAPI L1 KWs in CSIT using VPP Python bindings. Required for migrating away
- from VAT. Redesign of key components of PAPI Executor and PAPI history.
+#. TEST FRAMEWORK
- - **General Code Housekeeping**: Ongoing RF keywords optimizations,
- removal of redundant RF keywords.
+ - 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.
- - **Test suite generator**: Extend the test suite generator for ability to
- generate NIC permutation and search algorithm permutations from base
- suites.
+ - **CSIT test environment** version has been updated to ver. 11, see
+ :ref:`test_environment_versioning`.
- - **TOX verification**: Added verifications for test suite generator.
+ - **TCP TPUT profiles** had to be changed, as newer TRex versions
+ are not deterministic enough when deciding when to send an ACK.
-#. PRESENTATION AND ANALYTICS LAYER
+ - **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`.
- - **Graphs Layout Improvements**: Improved performance graphs layout
- for better readibility and maintenance: test grouping, axis
- labels, descriptions, other informative decoration.
+ - **General Code Housekeeping**: Ongoing code optimizations and bug
+ fixes.
-#. MISCELLANEOUS
+#. PRESENTATION AND ANALYTICS LAYER
- - **2n-dnv Tests (3rd Party)**: Published performance tests for 2n-
- dnv (2-Node Atom Denverton) from 3rd party testbeds running FD.io
- |csit-release| automated testing code.
- Only graphs for Packet Throughput and Speedup Multi-core and not
- for Packet Latency were published as there are no results for Packet
- Latency available.
+ - **C-Dash** `performance dashboard <http://csit.fd.io/>`_ got updated UI and
+ updated backend increasing its performance and robustness.

+
+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. |
++----+-----------------------------------------+--------------------------------------------------------------------+

+| | <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. |
