6 Changes in |csit-release|
7 -------------------------
9 #. VPP PERFORMANCE TESTS
11 - **Intel Xeon Ice Lake**: Performance test data for these platforms
12 continues to be provided by external Intel benchmarking labs
13 executing |csit-release| tests. For details about the physical
14 setup see :ref:`tested_physical_topologies`.
16 - **Reduction of tests**: Removed certain test variations executed
17 iteratively for the report (as well as in daily and weekly
18 trending) due to physical testbeds overload.
22 - **CSIT test environment** version has been updated to ver. 9, see
23 :ref:`test_environment_versioning`.
25 - **CSIT PAPI support**: Due to issues with PAPI performance, and
26 deprecation of VAT, CLI is used in CSIT for many VPP scale tests.
27 See known issues below.
29 - **General Code Housekeeping**: Ongoing code optimizations and bug
32 #. PRESENTATION AND ANALYTICS LAYER
34 - **Graphs improvements**: Updated Packet Latency graphs,
35 see :ref:`latency_methodology`.
49 Issues reported in previous releases which were fixed in this release:

52 | # | JiraID | Issue Description |
53 +====+=========================================+===========================================================================================================+
54 | 1 | `CSIT-1789 | AVF driver does not perform RSS in a deterministic way. |
55 | | <https://jira.fd.io/browse/CSIT-1789>`_ | VPP now uses the same RSS key with AVF driver as with DPDK driver. |
56 +----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
57 | 2 | `CSIT-1786 | IP4 and IP6 scale tests failing with no traffic forwarded. |
58 | | <https://jira.fd.io/browse/CSIT-1786>`_ | CSIT replaced the old single VAT command by file full of "exec" CLI commands executed by VAT. |
59 +----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
64 Issues reported in previous releases which still affect the current results.
66 +----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
67 | # | JiraID | Issue Description |
68 +====+=========================================+===========================================================================================================+
69 | 3 | `CSIT-1782 | Multicore AVF tests are failing when trying to create interface. |
70 | | <https://jira.fd.io/browse/CSIT-1782>`_ | Frequency is reduced by s CSIT workaround, but occasional failures do still happen. |
71 +----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
72 | 4 | `CSIT-1671 | All CSIT scale tests can not use PAPI due to much slower performance compared to VAT/CLI (it takes much |
73 | | <https://jira.fd.io/browse/CSIT-1671>`_ | longer to program VPP). This needs to be addressed on the PAPI side. |
74 | +-----------------------------------------+ Currently, the time critical code uses VAT running large files with exec statements and CLI commands. |
75 | | `VPP-1763 | Still, we needed to reduce the number of scale tests run to keep overall duration reasonable. |
76 | | <https://jira.fd.io/browse/VPP-1763>`_ | More improvements needed to achieve sufficient configuration speed. |
77 +----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
78 | 5 | `CSIT-1789 | IPSEC SW async scheduler tests show bad behavior. |
79 | | <https://jira.fd.io/browse/CSIT-1789>`_ | VPP code is not behaving correctly when crypto workers are the bottleneck. |
80 | +-----------------------------------------+ |
82 | | <https://jira.fd.io/browse/VPP-1998>`_ | |
83 +----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
84 | 6 | `CSIT-1785 | NAT44ED tests failing to establish all TCP sessions. |
85 | | <https://jira.fd.io/browse/CSIT-1785>`_ | At least for max scale, in allotted time (limited by session 500s timeout) due to worse |
86 | +-----------------------------------------+ slow path performance than previously measured and calibrated for. |
87 | | `VPP-1972 | CSIT removed the max scale NAT tests to avoid this issue. |
88 | | <https://jira.fd.io/browse/VPP-1972>`_ | |
89 +----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
90 | 7 | `CSIT-1791 | Performance regression in RDMA tests, due to CSIT environment changes. |
91 | | <https://jira.fd.io/browse/CSIT-1791>`_ | Two symptoms: 1. 10-20% regression across most tests. 2. DUT performance cap just below 38 Mpps. |
92 +----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
97 No new issues appeared in |csit-release| for VPP performance tests,
98 except for the performance changes listed below.
