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 - **AWS EC2 c5n**: Performance test data for AWS c5n instances has
17 been added to report for ip4, ip6 and ipsec tests.
19 - **Reduction of tests**: Removed certain test variations executed
20 iteratively for the report (as well as in daily and weekly
21 trending) due to physical testbeds overload.
25 - **CSIT test environment** version has been updated to ver. 8, see
26 :ref:`test_environment_versioning`.
28 - **CSIT in AWS environment**: Completed CSIT automation support for
29 AWS c5n instances environment, including weekly performance
30 trending tests execution.
32 - **CSIT PAPI support**: Due to issues with PAPI performance, and
33 deprecation of VAT, CLI is used in CSIT for many VPP scale tests.
34 See known issues below.
36 - **General Code Housekeeping**: Ongoing code optimizations and bug
39 #. PRESENTATION AND ANALYTICS LAYER
41 - **Graphs improvements**: Updated Packet Latency graphs,
42 see :ref:`latency_methodology`.
53 List of known issues in |csit-release| for VPP performance tests:
55 +----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
56 | # | JiraID | Issue Description |
57 +====+=========================================+===========================================================================================================+
58 | 1 | `CSIT-1782 | Multicore AVF tests are failing when trying to create interface. The issue persists after FVL FW upgrade. |
59 | | <https://jira.fd.io/browse/CSIT-1782>`_ | |
60 +----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
61 | 2 | `CSIT-1763 | Adapt ramp-up phase of nat44 tests for different frame sizes. |
62 | | <https://jira.fd.io/browse/CSIT-1763>`_ | Currently ramp-up phase rate and duration values are correctly set for tests with 64B frame size. |
63 +----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
64 | 3 | `CSIT-1671 | All CSIT scale tests can not use PAPI due to much slower performance compared to VAT/CLI (it takes much |
65 | | <https://jira.fd.io/browse/CSIT-1671>`_ | longer to program VPP). This needs to be addressed on the PAPI side. |
66 | +-----------------------------------------+ The usual PAPI library spends too much time parsing arguments, so even with async processing (hundreds of |
67 | | `VPP-1763 | commands in flight over socket), the VPP configuration for large scale tests (millions of messages) takes |
68 | | <https://jira.fd.io/browse/VPP-1763>`_ | too long. |
69 +----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
70 | 4 | `CSIT-1789 | AVF driver does not perform RSS in a deterministic way. |
71 | | <https://jira.fd.io/browse/CSIT-1789>`_ | This increases standard deviation of tests with small number of flows (mainly ipsec). |
72 +----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
73 | 5 | `CSIT-1780 | IPSEC SW async scheduler MRR tests failing with no traffic forwarded. |
74 | | <https://jira.fd.io/browse/CSIT-1780>`_ | |
75 +----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
76 | 6 | `CSIT-1786 | IP4 and IP6 scale tests failing with no traffic forwarded. |
77 | | <https://jira.fd.io/browse/CSIT-1786>`_ | Issue reported to VPP devs. |
78 +----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
79 | 7 | `CSIT-1785 | NAT44ED tests failing to establish all TCP sessions. |
80 | | <https://jira.fd.io/browse/CSIT-1785>`_ | |
81 +----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
82 | 8 | `CSIT-1791 | Performance regression in RDMA tests, due to CSIT environment changes. |
83 | | <https://jira.fd.io/browse/CSIT-1791>`_ | |
