Release Notes
=============
-Changes in CSIT |release|
+Changes in |csit-release|
-------------------------
-#. **VPP performance tests**
-
- - *MRR tests* - New Maximum Receive Rate tests measure the packet
- forwarding rate under the maximum load offered by traffic
- generator over a set trial duration, regardless of packet loss.
- MRR tests are used for continuous performance trending and for
- comparison between releases.
-
- - *Service Chaining with SRv6* - New SRv6 (Segment Routing IPv6) proxy
- tests measure performance of SRv6 Endpoint fronting SR-unaware
- appliance via masquerading (End.AM), dynamic proxy (End.AD) or
- static proxy (End.AS) SR functions.
-
-#. **Presentation and Analytics Layer**
-
- - *Performance trending* - Added continuous performance trending and
- analysis. New Performance Trending and Performance Analysis jobs
- executed regular throughput tests, with results being subsequently
- analysed and trend and anomalies summarized and presented in VPP
- Performance Dashboard and trendline graphs.
-
-#. **Test Framework Optimizations**
-
- - *Performance tests efficiency* - Qemu build/install optimizations,
- warmup phase handling, vpp restart handling. Resulted in improved
- stability and reduced total execution time by 30% for single pkt
- size e.g. 64B/78B.
-
- - *General code housekeeping* - ongoing RF keywords optimizations,
- removal of redundant RF keywords.
-
-Performance Changes
--------------------
-
-Relative performance changes in measured packet throughput in CSIT
-|release| are calculated against the results from CSIT |release-1|
-report. Listed mean and standard deviation values are computed based on
-a series of the same tests executed against respective VPP releases to
-verify test results repeatibility, with percentage change calculated for
-mean values. Note that the standard deviation is quite high for a small
-number of packet throughput tests, what indicates poor test results
-repeatability and makes the relative change of mean throughput value not
-fully representative for these tests. The root causes behind poor
-results repeatibility vary between the test cases.

+ - **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`.
-.. note::
+ - **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`.
- Test results have been generated by
- `FD.io test executor vpp mrr jobs <https://jenkins.fd.io/view/csit/job/csit-vpp-perf-mrr-daily-master/>`_
- with Robot Framework result files csit-vpp-perf-mrr-daily-master__*__output.xml.gz
- `archived here <https://docs.fd.io/csit/master/trending/_static/archive/>`_.
+ - **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`.
-Comparison Across Testbeds
---------------------------
+ - **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.
-.. warning::
+#. TEST FRAMEWORK
- TODO: Add:
+ - **CSIT test environment** version has been updated to ver. 9, see
+ :ref:`test_environment_versioning`.
- Table 1.
- Test Case 3-Node Hsw 3-Node Skx Skx vs. Hsw Delta [%]
+ - **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`.
- Table 2.
- Test Case 3-Node Skx 2-Node Skx 2-Node vs. 3-Node Delta [%]
+ - **General Code Housekeeping**: Ongoing code optimizations and bug
+ fixes.

++====+=========================================+===========================================================================================================+
+| 3 | `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. |
++----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
+| 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. |
++----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
+| 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. |
+| +-----------------------------------------+ |
+| | `VPP-1998 | |
+| | <https://jira.fd.io/browse/VPP-1998>`_ | |
++----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
+| 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. |
+| | <https://jira.fd.io/browse/VPP-1972>`_ | |
++----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
+| 7 | `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. |

+| 1 | `CSIT-1789 | AVF driver does not perform RSS in a deterministic way. |
