-CSIT Release Notes\r
-==================\r
-\r
-Changes in CSIT |release|\r
--------------------------\r
-\r
-#. Test environment changes in VPP data plane performance tests:\r
-\r
- - Further characterization and optimizations of VPP vhost-user and VM test\r
- methodology and test environment;\r
-\r
- - Tests with varying Qemu virtio queue (a.k.a. vring) sizes:\r
- [vr256] default 256 descriptors, [vr1024] 1024 descriptors to\r
- optimize for packet throughput;\r
-\r
- - Tests with varying Linux :abbr:`CFS (Completely Fair Scheduler)`\r
- settings: [cfs] default settings, [cfsrr1] :abbr:`CFS (Completely Fair\r
- Scheduler)` RoundRobin(1) policy applied to all data plane threads\r
- handling test packet path including all VPP worker threads and all Qemu\r
- testpmd poll-mode threads;\r
-\r
- - Resulting test cases are all combinations with [vr256,vr1024] and\r
- [cfs,cfsrr1] settings;\r
-\r
- - For more detail see performance results observations section in\r
- this report;\r
-\r
-#. Code updates and optimizations in CSIT performance framework:\r
-\r
- - Complete CSIT framework code revision and optimizations as descried\r
- on CSIT wiki page `Design_Optimizations\r
- <https://wiki.fd.io/view/CSIT/Design_Optimizations>`_.\r
-\r
- - For more detail see the :ref:`CSIT Framework Design <csit-design>` section\r
- in this report;\r
-\r
-#. Changes to CSIT driver for TRex Traffic Generator:\r
-\r
- - Complete refactor of TRex CSIT driver;\r
-\r
- - Introduction of packet traffic profiles to improve usability and\r
- manageability of traffic profiles for a growing number of test\r
- scenarios.\r
-\r
- - Support for packet traffic profiles to test IPv4/IPv6 stateful and\r
- stateless DUT data plane features;\r
-\r
-#. Added VPP performance tests\r
-\r
- - **Linux Container VPP memif virtual interface tests**\r
-\r
- - VPP Memif virtual interface (shared memory interface) tests\r
- interconnecting VPP instances over memif. VPP vswitch\r
- instance runs in bare-metal user-mode handling Intel x520 NIC\r
- 10GbE interfaces and connecting over memif (Master side) virtual\r
- interfaces to another instance of VPP running in bare-metal Linux\r
- Container (LXC) with memif virtual interfaces (Slave side). LXC\r
- runs in a priviliged mode with VPP data plane worker threads\r
- pinned to dedicated physical CPU cores per usual CSIT practice.\r
- Both VPP run the same version of software. This test topology is\r
- equivalent to existing tests with vhost-user and VMs.\r
-\r
- - **Stateful Security Groups**\r
-\r
- - New tests of VPP stateful security-groups a.k.a. acl-plugin\r
- functionally compatible with networking-vpp OpenStack;\r
-\r
- - New tested security-groups access-control-lists (acl)\r
- configuration variants include: [iaclNsl] input acl stateless,\r
- [oaclNsl] output acl stateless, [iaclNsf] input acl stateful\r
- a.k.a. reflect, [oaclNsf] output acl stateful a.k.a. reflect,\r
- where N is number of access-control-entries (ace) in the acl.\r
-\r
- - Testing packet flows transmitted by TG: 100, 10k, 100k, always\r
- hitting the last permit entry in acl.\r
-\r
- - **VPP vhost and VM tests**\r
-\r
- - New VPP vhost-user and VM test cases to benchmark performance of\r
- VPP and VM topologies with Qemu and CFS policy combinations of\r
- [vr256,vr1024] x [cfs,cfsrr1];\r
-\r
- - Statistical analysis of repeatibility of results;\r
-\r
-Performance Improvements\r
-------------------------\r
-\r
-Substantial improvements in measured packet throughput have been observed in a\r
-number of CSIT |release| tests listed below, with relative increase of\r
-double-digit percentage points. Relative improvements for this release are\r
-calculated against the test results listed in CSIT |release-1| report. The\r
-comparison is calculated between the mean values based on collected and\r
-archived test results' samples for involved VPP releases. Standard deviation\r
-has been also listed for CSIT |release|. VPP-16.09 and VPP-17.01 numbers are\r
-provided for reference.\r

+Release Notes
+=============
+
+Changes in |csit-release|
+-------------------------
+
+#. VPP PERFORMANCE TESTS
+
+ - **Regressions with DPDK drivers**: Change from DPDK v21.08 to DPDK
+ v21.11 introduced regression across all tests using dpdk
+ drivers (with dpdk_plugin loaded). Compared to previous VPP
+ release performance drop varies in the range of -15% to -6%,
+ depending on test. It is related to updated MTU checks within
+ DPDK code and associated VPP code changes. See
+ `VPP v2202 release notes <https://s3-docs.fd.io/vpp/22.02/aboutvpp/releasenotes/v22.02.html>`_
+ and :ref:`vpp_known_issues`.
+
+ - **Number of CSIT 9000B frame tests failing**: tests with higher
+ encapsulation overhead are failing due to exceeding default
+ Ethernet Maximum Frame Size value that has been reduced by MTU
+ related VPP code changes. See
+ `VPP v2202 release notes <https://s3-docs.fd.io/vpp/22.02/aboutvpp/releasenotes/v22.02.html>`_
+ and :ref:`vpp_known_issues`.
+
+ - **Intel Xeon Ice Lake**: Performance test data for these platforms
+ is now provided by testbeds newly installed in FD.io CSIT labs.
+ For details about the physical setup see
+ :ref:`physical_testbeds_2n_icx` and
+ :ref:`physical_testbeds_3n_icx`.
+
+ - **Arm Ampere Altra**: Performance test data for these platforms
+ is now provided by testbeds newly installed in FD.io CSIT labs.
+ For details about the physical setup see
+ :ref:`physical_testbeds_3n_alt`.
+
+ - **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.
+
+ - **RC2 coverage test data is used for 2n-icx test bed**: There is only
+ one 2n-icx test bed and the amount of tests is large (same as 2n-skx with 4
+ test beds), so we decided to use test data already available from RC2
+ testing.
+
+#. TEST FRAMEWORK
+
+ - **CSIT test environment** version has been updated to ver. 10, see
+ :ref:`test_environment_versioning`.
+
+ - **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 improvements**: Updated Packet Latency graphs,
+ see :ref:`latency_methodology`.

+| # | 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-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. |
++----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
+| 3 | `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>`_ | |
++----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
+| 4 | `CSIT-1791 | Performance regression in RDMA tests, due to CSIT environment changes. |
+| | <https://jira.fd.io/browse/CSIT-1791>`_ | Two symptoms: 1. 10-20% regression across most tests. 2. DUT performance cap just below 38 Mpps. |
