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

47 +----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
48 | # | JiraID | Issue Description |
49 +====+=========================================+===========================================================================================================+
50 | 1 | `CSIT-570 | Sporadic (1 in 200) NDR discovery test failures on x520. DPDK reporting rx-errors, indicating L1 issue. |
51 | | <https://jira.fd.io/browse/CSIT-570>`_ | Suspected issue with HW combination of X710-X520 in LF testbeds. Not observed outside of LF testbeds. |
52 +----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
53 | 2 | `VPP-662 | 9000B packets not supported by NICs VIC1227 and VIC1387. |
54 | | <https://jira.fd.io/browse/VPP-662>`_ | |
55 +----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
56 | 3 | `CSIT-1498 | Memif tests are sporadically failing on initialization of memif connection. |
57 | | <https://jira.fd.io/browse/CSIT-1498>`_ | |
58 +----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
59 | 4 | `VPP-1677 | 9000B ip4 nat44: VPP crash + coredump. |
60 | | <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). |
61 +----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
62 | 5 | `CSIT-1591 | All CSIT scale tests can not use PAPI due to much slower performance compared to VAT/CLI (it takes much |
63 | | <https://jira.fd.io/browse/CSIT-1499>`_ | longer to program VPP). This needs to be addressed on the PAPI side. |
64 | +-----------------------------------------+ |
66 | | <https://jira.fd.io/browse/VPP-1763>`_ | |
67 +----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
68 | 6 | `VPP-1675 | IPv4 IPSEC 9000B packet tests are failing as no packet is forwarded. |
69 | | <https://jira.fd.io/browse/VPP-1675>`_ | Reason: chained buffers are not supported. |
70 +----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
71 | 7 | `CSIT-1593 | IPv4 AVF 9000B packet tests are failing on 3n-skx while passing on 2n-skx. |

73 +----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
74 | 8 | `CSIT-1675 | Intel Xeon 2n-skx, 3n-skx and 2n-clx testbeds behaviour and performance became inconsistent following |
75 | | <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 |
76 | | | packages (skx ucode 0x2000064, clx ucode 0x500002c). VPP as well as DPDK L3fwd tests are affected. |
