#. VPP PERFORMANCE TESTS
- - **AF_XDP**: Added af_xdp driver support for all test cases. Test
- results will be added in sub-sequent CSIT-2106 report.
-
- - **GTPU tunnel**: Added GTPU HW Offload IPv4 routing tests.
-
- - **Intel Xeon Ice Lake**: Added initial test data for these
- platforms. Current CSIT-2106 report data for Intel Xeon Ice Lake
- comes from an external source (Intel labs running CSIT code on
- "8360Y D Stepping" and "6338N" processors). For details about the
- physical setup see :ref:`tested_physical_topologies`. Tested
- VPP and CSIT versions are pre-release, VPP
- 21.06-rc0~779-gd640ae52f.
-
- - **MLRsearch improvements**: Added support for multiple packet
- throughput rates in a single search, each rate is associated
- with a distinct Packet Loss Ratio (PLR) criterion. Previously
- only Non Drop Rate (NDR) (PLR=0) and single Partial Drop Rate
- (PDR) (PLR<0.5%) were supported. Implemented number of
- optimizations improving rate discovery efficiency.
-
- - **Reduction of tests**: Removed obsolete VPP use cases and
- superfluous test combinations from continuous and report test
- executions, including:
-
- - All vts tests, obsolete use cases.
- - dot1q tests apart from dot1q-l2bd, superfluous combinations.
- - -100flows, -100kflows in all acl tests.
- - nat44 tests
-
- - -pps tests, replaced by -tput tests.
- - h1-p1-s1 single session tests, unessential combination.
- - h4096-p63-s258048 tests, unessential scale combination.
-
- - ipsec tests
-
- - ethip4ipsectptlispgpe.
- - policy-aes128gcm.
- - policy-aes128cbc-hmac256sha.
- - policy-aes128cbc-hmac512sha.
- - int-aes128cbc-hmac256sha.
- - scale of
-
- - 400tnlsw.
- - 5000tnlsw.
- - 20000tnlsw.
- - 60000tnlsw.
+ - **Intel Xeon Ice Lake**: Performance test data for these platforms
+ continues to be provided by external Intel benchmarking labs
+ executing |csit-release| tests. For details about the physical
+ setup see :ref:`tested_physical_topologies`.
-#. TEST FRAMEWORK
-
- - **Telemetry retouch**: Refactored telemetry retrieval from DUTs and
- SUTs. Included VPP perfmon plugin telemetry with all perfmon
- bundles available in VPP release.
+ - **AWS EC2 c5n**: Performance test data for AWS c5n instances has
+ been added to report for ip4, ip6 and ipsec tests.
- - **Upgrade to Ubuntu 20.04 LTS**: Re-installed base operating system
- to Ubuntu 20.04.2 LTS. Upgrade included also baseline Docker
- containers used for spawning topology.
+ - **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.
- - **TRex upgrade v2.86 to v2.88**: Included move to DPDK 21.02 and
- changed the way egress low latency queues are used in FVL NICs.
- This broke latency measurements for majority of FVL NICs in
- CSIT. Latency values look better after upgrading FVL FW on TRex
- servers, but still somewhat higher than before the TRex upgrade.
- Tracked by `CSIT-1790 <https://jira.fd.io/browse/CSIT-1790>`_.
+#. TEST FRAMEWORK
- - **CSIT test environment** version has been updated to ver. 7, see
+ - **CSIT test environment** version has been updated to ver. 8, see
:ref:`test_environment_versioning`.
- - **CSIT in AWS environment**: Added CSIT support for AWS c5n
- instances environment. Test results will be added in sub-sequent
- CSIT-2106 report.
+ - **CSIT in AWS environment**: Completed CSIT automation support for
+ AWS c5n instances environment, including weekly performance
+ trending tests execution.
- - **CSIT PAPI support**: Due to issues with PAPI performance, VAT is
- still used in CSIT for all VPP scale tests. See known issues
- below.
+ - **CSIT PAPI support**: Due to issues with PAPI performance, and
+ deprecation of VAT, CLI is used in CSIT for many VPP scale tests.
+ See known issues below.
- **General Code Housekeeping**: Ongoing code optimizations and bug
- fixes.

| # | JiraID | Issue Description |
+====+=========================================+===========================================================================================================+
-| 1 | `CSIT-1782 | Multicore AVF tests are failing when trying to create interface. |
-| | <https://jira.fd.io/browse/CSIT-1782>`_ | |
+----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
-| 2 | `CSIT-1763 | Adapt ramp-up phase of nat44 tests for different frame sizes. |
-| | <https://jira.fd.io/browse/CSIT-1763>`_ | Currently ramp-up phase rate and duration values are correctly set for tests with 64B frame size. |
+| 1 | `CSIT-1789 | AVF driver does not perform RSS in a deterministic way. |
+| | <https://jira.fd.io/browse/CSIT-1789>`_ | VPP now uses the same RSS key with AVF driver as with DPDK driver. |
+----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
-| 3 | `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. |
-| +-----------------------------------------+ The usual PAPI library spends too much time parsing arguments, so even with async processing (hundreds of |
-| | `VPP-1763 | commands in flight over socket), the VPP configuration for large scale tests (millions of messages) takes |
-| | <https://jira.fd.io/browse/VPP-1763>`_ | too long. |
+| 2 | `CSIT-1786 | IP4 and IP6 scale tests failing with no traffic forwarded. |
+| | <https://jira.fd.io/browse/CSIT-1786>`_ | CSIT replaced the old single VAT command by file full of "exec" CLI commands executed by VAT. |
+----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
-| 4 | `CSIT-1789 | AVF driver does not perform RSS in a deterministic way. |
-| | <https://jira.fd.io/browse/CSIT-1789>`_ | This increases standard deviation of tests with small number of flows (mainly ipsec). |

+| 3 | `CSIT-1782 | Multicore AVF tests are failing when trying to create interface. |
+| | <https://jira.fd.io/browse/CSIT-1782>`_ | Frequency is reduced by s CSIT workaround, but occasional failures do still happen. |
+----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
-| 5 | `CSIT-1790 | Broken TRex latency measurements with TRex v2.88, DPDK 21.02 and FVL FW 6.01. |
-| | <https://jira.fd.io/browse/CSIT-1790>`_ | High latency O(5msec) for all VPP and testpmd/l3fwd test cases for FVL NICs with FW 6.01. |
+| 4 | `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. |

-| | <https://jira.fd.io/browse/CSIT-1780>`_ | |
+| 5 | `CSIT-1789 | IPSEC SW async scheduler tests show bad behavior. |
+| | <https://jira.fd.io/browse/CSIT-1789>`_ | VPP code is not behaving correctly when crypto workers are the bottleneck. |

+| 6 | `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. |
