#. VPP PERFORMANCE TESTS
- - **Intel Xeon 2n-skx, 3n-skx and 2n-clx testbeds**: VPP performance
- test data is not included in this report version. This is due to
- the lower performance and behaviour inconsistency of these
- systems following the upgrade of processor microcode packages
- (skx ucode 0x2000064, clx ucode 0x500002c), done as part of
- updating Ubuntu 18.04 LTS kernel version. Tested VPP and DPDK
- applications (L3fwd) are affected. Skx and Clx test data will be
- added in subsequent maintenance report version(s) once the issue
- is resolved. See :ref:`vpp_known_issues`.
-
- - **Service density 2n-skx tests**: Added new NF density tests with
- IPsec encryption between DUTs.
-
- - **AVF tests**: Full test coveraged based on code changes in CSIT
- core layer (driver/interface awareness) and generated by suite
- generator (Intel Fortville NICs only).
-
- - **Hoststack tests**: Major refactor of VPP Hoststack TCP/IP
- performance tests using WRK generator talking to the VPP HTTP
- static server plugin measuring connections per second and
- requests per second. Added new iperf3 with LDPreload tests,
- iperf3/LDPreload tests with packet loss induced via the VPP NSIM
- (Network Simulator) plugin, and QUIC/UDP/IP transport tests.
- All of the new tests measure goodput through the VPP Hoststack
- from client to server.
-
- - **Latency HDRHistogram**: Added High Dynamic Range Histogram
- latency measurements based on the new capability in TRex traffic
- generator. HDRH latency data presented in latency packet
- percentile graphs and in detailed results tables.
-
- - **Mellanox MCX556A-EDAT tests**: Added tests with Mellanox
- ConnectX5-2p100GE NICs in 2n-clx testbeds using VPP native rdma
- driver.
-
- - **IPsec reconfiguration tests**: Added tests measuring the impact
- of IPsec tunnels creations and removals.
-
- - **Load Balancer tests**: Added VPP performance tests for Maglev,
- L3DSR (Direct Server Return), Layer 4 Load Balancing NAT Mode.
+ - **Enhanced and added VPP hoststack tests** to daily and weekly
+ trending including: Quic VPP Echo, UDP+TCP LD_PRELOAD iPerf3,
+ LD_PRELOAD NGINX.
-#. TEST FRAMEWORK
+ - **Added Nvidia/Mellanox DPDK tests** to daily and weekly trending
+ and report, in addition to RDMA_CORE ones that were already
+ there.
- - **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.
+ - **Jumbo frames tests** got fixed and re-added number of to report
+ coverage tests.
- - **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.
+ - **Intel Xeon SKX performance testbeds** got decommissioned and
+ removed from FD.io performance lab.
+
+#. TEST FRAMEWORK
- - **Test Suite Generator**: Added capability to generate suites for
- different drivers per NIC model including DPDK, AVF, RDMA.
- Extended coverage for all tests.
+ - **CSIT test environment** version has not changed from ver. 11 used
+ in previous release, see :ref:`test_environment_versioning`.
- - **General Code Housekeeping**: Ongoing RF keywords optimizations,
- removal of redundant RF keywords and aligning of suite/test
- setup/teardowns.
+ - **CSIT PAPI optimizations for scale** got applied improving PAPI
+ programming speed especially for large scale tests. VAT has been
+ now completely deprecated from CSIT.
+ - **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.
-
- - **Latency graphs**: Min/Avg/Max group bar latency graphs are
- replaced with packet latency percentile distributon at different
- background packet loads based on TRex latency hdrhistogram
- measurements.
-
-..
- // Alternative Note for 1st Bullet when bad microcode Skx, Clx results are published
- - **Intel Xeon 2n-skx, 3n-skx and 2n-clx testbeds**: VPP performance
- test data is included in this report version, but it shows lower
- performance and behaviour inconsistency of these systems
- following the upgrade of processor microcode packages (skx ucode
- 0x2000064, clx ucode 0x500002c) as part of updating Ubuntu 18.04
- LTS kernel version. Tested VPP and DPDK applications (L3fwd) are
- affected. Skx and Clx test data will be corrected in subsequent
- maintenance report version(s) once the issue is resolved. See
- :ref:`vpp_known_issues`.
+ - `Performance dashboard `_ got updated with
+ addition of VPP telemetry trending across all VPP tests. A number
+ of code and AWS resource usage optimizations got applied to the
+ data processing pipeline and UI frontend and backend.

+====+=========================================+===========================================================================================================+
-| 1 | `CSIT-570 | Sporadic (1 in 200) NDR discovery test failures on x520. DPDK reporting rx-errors, indicating L1 issue. |
-| | `_ | Suspected issue with HW combination of X710-X520 in LF testbeds. Not observed outside of LF testbeds. |
+| 1 | `CSIT-1782 | Multicore AVF tests are failing when trying to create interface. |
+| | `_ | Frequency is reduced by CSIT workaround, but occasional failures do still happen. |
++----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
+| 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 |
+| +-----------------------------------------+ slow path performance than previously measured and calibrated for. |
+| | `VPP-1972 | CSIT removed the max scale NAT tests to avoid this issue. |
+| | `_ | |
++----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
+| 3 | `CSIT-1799 | All NAT44-ED 16M sessions CPS scale tests fail while setting NAT44 address range. |
+| | `_ | |
++----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
+| 4 | `CSIT-1800 | All Geneve L3 mode scale tests (1024 tunnels) are failing. |
+| | `_ | |
+----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
-| 2 | `VPP-662 | 9000B packets not supported by NICs VIC1227 and VIC1387. |
-| | `_ | |
+| 5 | `CSIT-1801 | 9000B payload frames not forwarded over tunnels due to violating supported Max Frame Size (VxLAN, LISP, |
+| | `_ | SRv6). |

+| | `_ | |
+----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
-| 5 | `CSIT-1591 | 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. |

+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), |
