4 Changes in |csit-release|
5 -------------------------
6 #. VPP PERFORMANCE TESTS
7 - CSIT test environment is now versioned, with ver. 1 associated
8 with CSIT rls1908 git branch as of 2019-08-21, and ver. 2
9 associated with CSIT rls2001 and master git branches as of
11 - To identify performance changes due to VPP code changes from
12 v20.01.0 to v20.05.0, both have been tested in CSIT environment
13 ver. 2 and compared against each other. All substantial
14 progressions has been marked up with RCA analysis. See
15 :ref:`vpp_compare_current_vs_previous_release` and
16 :ref:`vpp_known_issues`.
18 - **CSIT PAPI support**: Due to issues with PAPI performance, VAT is
19 still used in CSIT for all VPP scale tests. See known issues below.
20 - **General Code Housekeeping**: Ongoing RF keywords optimizations,
21 removal of redundant RF keywords and aligning of suite/test
23 #. PRESENTATION AND ANALYTICS LAYER
24 - **Graphs layout improvements**: Improved performance graphs layout
25 for better readibility and maintenance: test grouping, axis
26 labels, descriptions, other informative decoration.

33 +----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
34 | # | JiraID | Issue Description |
35 +====+=========================================+===========================================================================================================+
36 | 1 | `CSIT-570 | Sporadic (1 in 200) NDR discovery test failures on x520. DPDK reporting rx-errors, indicating L1 issue. |
37 | | <https://jira.fd.io/browse/CSIT-570>`_ | Suspected issue with HW combination of X710-X520 in LF testbeds. Not observed outside of LF testbeds. |
38 +----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
39 | 2 | `VPP-662 | 9000B packets not supported by NICs VIC1227 and VIC1387. |
40 | | <https://jira.fd.io/browse/VPP-662>`_ | |
41 +----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
42 | 3 | `CSIT-1498 | Memif tests are sporadically failing on initialization of memif connection. |
43 | | <https://jira.fd.io/browse/CSIT-1498>`_ | |
44 +----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
45 | 4 | `VPP-1677 | 9000B ip4 nat44: VPP crash + coredump. |
46 | | <https://jira.fd.io/browse/VPP-1677>`_ | VPP crashes very often in case that NAT44 is configured and it has to process IP4 jumbo frames (9000B). |
47 +----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
48 | 5 | `CSIT-1591 | All CSIT scale tests can not use PAPI due to much slower performance compared to VAT/CLI (it takes much |
49 | | <https://jira.fd.io/browse/CSIT-1499>`_ | longer to program VPP). This needs to be addressed on the PAPI side. |
50 | +-----------------------------------------+ |
52 | | <https://jira.fd.io/browse/VPP-1763>`_ | |
53 +----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
54 | 6 | `VPP-1675 | IPv4 IPSEC 9000B packet tests are failing as no packet is forwarded. |
55 | | <https://jira.fd.io/browse/VPP-1675>`_ | Reason: chained buffers are not supported. |
56 +----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
57 | 7 | `CSIT-1593 | IPv4 AVF 9000B packet tests are failing on 3n-skx while passing on 2n-skx. |

59 +----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
60 | 8 | `CSIT-1675 | Intel Xeon 2n-skx, 3n-skx and 2n-clx testbeds behaviour and performance became inconsistent following |
61 | | <https://jira.fd.io/browse/CSIT-1675>`_ | the upgrade to the latest Ubuntu 18.04 LTS kernel version (4.15.0-72-generic) and associated microcode |
62 | | | packages (skx ucode 0x2000064, clx ucode 0x500002c). VPP as well as DPDK L3fwd tests are affected. |
