   7 #. VPP PERFORMANCE TESTS
   8
   9    - **Intel Xeon 2n-skx, 3n-skx and 2n-clx testbeds**: VPP performance
  10      test data is not included in this report version. This is due to
  11      the lower performance and behaviour inconsistency of these
  12      systems following the upgrade of processor microcode packages
  13      (skx ucode 0x2000064, clx ucode 0x500002c), done as part of
  14      updating Ubuntu 18.04 LTS kernel version. Tested VPP and DPDK
  15      applications (L3fwd) are affected. Skx and Clx test data will be
  16      added in subsequent maintenance report version(s) once the issue
  17      is resolved. See :ref:`vpp_known_issues`.
  18
  19    - **Service density 2n-skx tests**: Added new NF density tests with
  20      IPsec encryption between DUTs.
  21
  22    - **AVF tests**: Full test coveraged based on code changes in CSIT
  23      core layer (driver/interface awareness) and generated by suite
  24      generator (Intel Fortville NICs only).
  25
  26    - **Hoststack tests**: Major refactor of VPP Hoststack TCP/IP
  27      performance tests using WRK generator talking to the VPP HTTP
  28      static server plugin measuring connections per second and
  29      requests per second. Added new iperf3 with LDPreload tests,
  30      iperf3/LDPreload tests with packet loss induced via the VPP NSIM
  31      (Network Simulator) plugin, and QUIC/UDP/IP transport tests.
  32      All of the new tests measure goodput through the VPP Hoststack
  33      from client to server.
  34
  35    - **Latency HDRHistogram**: Added High Dynamic Range Histogram
  36      latency measurements based on the new capability in TRex traffic
  37      generator. HDRH latency data presented in latency packet
  38      percentile graphs and in detailed results tables.
  39
  40    - **Mellanox MCX556A-EDAT tests**: Added tests with Mellanox
  41      ConnectX5-2p100GE NICs in 2n-clx testbeds using VPP native rdma
  42      driver.
  43
  44    - **IPsec reconfiguration tests**: Added tests measuring the impact
  45      of IPsec tunnels creations and removals.
  46
  47    - **Load Balancer tests**: Added VPP performance tests for Maglev,
  48      L3DSR (Direct Server Return), Layer 4 Load Balancing NAT Mode.
  49
  50 #. TEST FRAMEWORK
  51
  52    - **CSIT Python3 support**: Full migration of CSIT from Python2.7 to
  53      Python3.6. This change includes library migration, PIP dependency
  54      upgrade, CSIT container images, infrastructure packages
  55      ugrade/installation.
  56
  57    - **CSIT PAPI support**: Finished conversion of CSIT VAT L1 keywords
  58      to PAPI L1 KWs in CSIT using VPP Python bindings (VPP PAPI).
  59      Redesign of key components of PAPI Socket Executor and PAPI
  60      history. Due to issues with PAPI performance, VAT is still used
  61      in CSIT for all VPP scale tests. See known issues below.
  62
  63    - **Test Suite Generator**: Added capability to generate suites for
  64      different drivers per NIC model including DPDK, AVF, RDMA.
  65      Extended coverage for all tests.
  66
  67    - **General Code Housekeeping**: Ongoing RF keywords optimizations,
  68      removal of redundant RF keywords and aligning of suite/test
  69      setup/teardowns.
  70
  71 #. TEST ENVIRONMENT
  72
  73    - **TRex Fortville NIC Performance**: Received FVL fix from Intel
  74      resolving TRex low throughput issue. TRex per FVL NIC throughput
  75      increased from ~27 Mpps to the nominal ~37 Mpps. For detail see
  76      `CSIT-1503 <https://jira.fd.io/browse/CSIT-1503>`_ and `TRex-519
  77      <https://trex-tgn.cisco.com/youtrack/issue/trex-519>`_].
  78
  79    - **New Intel Xeon Cascadelake Testbeds**: Added performance tests
  80      for 2-Node-Cascadelake (2n-clx) testbeds with x710, xxv710 and
  81      mcx556a-edat NIC cards.
  82
  83 #. PRESENTATION AND ANALYTICS LAYER
  84
  85    - **Graphs layout improvements**: Improved performance graphs layout
  86      for better readibility and maintenance: test grouping, axis
  87      labels, descriptions, other informative decoration.
  88
  89    - **Latency graphs**: Min/Avg/Max group bar latency graphs are
  90      replaced with packet latency percentile distributon at different
  91      background packet loads based on TRex latency hdrhistogram
  92      measurements.

  95     // Alternative Note for 1st Bullet when bad microcode Skx, Clx results are published
  96     - **Intel Xeon 2n-skx, 3n-skx and 2n-clx testbeds**: VPP performance
  97       test data is included in this report version, but it shows lower
  98       performance and behaviour inconsistency of these systems
  99       following the upgrade of processor microcode packages (skx ucode
 100       0x2000064, clx ucode 0x500002c) as part of updating Ubuntu 18.04
 101       LTS kernel version. Tested VPP and DPDK applications (L3fwd) are
 102       affected. Skx and Clx test data will be corrected in subsequent
 103       maintenance report version(s) once the issue is resolved. See

 120 | 1  | `CSIT-570                               | Sporadic (1 in 200) NDR discovery test failures on x520. DPDK reporting rx-errors, indicating L1 issue.   |
 121 |    | <https://jira.fd.io/browse/CSIT-570>`_  | Suspected issue with HW combination of X710-X520 in LF testbeds. Not observed outside of LF testbeds.     |
 122 +----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
 123 | 2  | `VPP-662                                | 9000B packets not supported by NICs VIC1227 and VIC1387.                                                  |

 126 | 3  | `CSIT-1498                              | Memif tests are sporadically failing on initialization of memif connection.                               |
 127 |    | <https://jira.fd.io/browse/CSIT-1498>`_ |                                                                                                           |

 130 |    | <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).   |
 131 +----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
 132 | 5  | `CSIT-1591                              | All CSIT scale tests can not use PAPI due to much slower performance compared to VAT/CLI (it takes much   |
 133 |    | <https://jira.fd.io/browse/CSIT-1499>`_ | longer to program VPP). This needs to be addressed on the PAPI side.                                      |
 134 |    +-----------------------------------------+                                                                                                           |

 138 | 6  | `VPP-1675                               | IPv4 IPSEC 9000B packet tests are failing as no packet is forwarded.                                      |
 139 |    | <https://jira.fd.io/browse/VPP-1675>`_  | Reason: chained buffers are not supported.                                                                |

 143 +----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
 144 | 8  | `CSIT-1675                              | Intel Xeon 2n-skx, 3n-skx and 2n-clx testbeds behaviour and performance became inconsistent following     |
 145 |    | <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    |
 146 |    |                                         | packages (skx ucode 0x2000064, clx ucode 0x500002c). VPP as well as DPDK L3fwd tests are affected.        |
