7 #. VPP PERFORMANCE TESTS
8
9    - **BMRR Throughput**: MRR (Maximum Receive Rate) test code has been
10      updated with a configurable burst MRR parameters: trial duration
11      and number of trials in a single burst. Enables a new Burst MRR
12      (BMRR for short) methodology for more precise performance
13      trending. See updated :ref:`performance_test_methodology` section
14      for more details.
15
16    - **2n-skx tests**: Added performamce tests for 2n-skx (2-Node Xeon
17      Skylake) testbeds: focus on baseline and scale tests, including
18      VM vhost and Container memif tests.
19
20    - **3n-skx tests**: Added performamce tests for 3n-skx (3-Node Xeon
21      Skylake) testbeds: VM vhost and Container memif tests.
22
23    - **VXLAN Scale Tests**: Added performamce tests for VXLAN scale with
24      dot1q and VPP L2BD.
25
26    - **AVF Driver Tests**: Added performamce tests for i40e AVF driver
27      on VPP, no DPDK required.
28
29    - **QAT**: Fixed reoccuring issues with QAT crypto accelerator cards.
30
31    - **K8s/Ligato in Trending**: Added K8s/Ligato Container memif tests
32      to daily trending.
33
34 #. TEST FRAMEWORK
35
36    - **Experimental Soak Tests**: Added performamce soak tests framework
37      code for extended time duration tests and  throughput discovery
38      at given PLR and at give total test time e.g. minutes, hours,
39      days, weeks, months, years. See updated
40      :ref:`performance_test_methodology` section for more details.
41
42    - **Trending Tests BMRR**: Used new Burst MRR (BMRR) tests for daily
43      trending.
44
45    - **Per VPP Patch Performance Checks**: Per VPP gerrit patch vs.
46      parent performance tests, anomaly detection and no verify voting
47      (-1/0/+1) yet. Manual trigger only. Not "marketed" to FD.io
48      community yet to avoid excessive LFN FD.io physical performance
49      testbed blocking.
50
51    - **Patch-on-Patch Infra**: Added capability to run performance tests
52      using CSIT gerrit patch code testing VPP gerrit patch code, i.e.
53      before any VPP and/or CSIT code is merged into git branch.
54
55    - **CSIT PAPI Support**: Initial implementation of PAPI L1 KWs in
56      CSIT using VPP Python bindings. Required for migraing away from
57      VAT. Very few L1 KWs implemented ("show version", "show
58      interfaces").
59
60    - **General Code Housekeeping**: Ongoing RF keywords optimizations,
61      removal of redundant RF keywords.
62
63 #. PRESENTATION AND ANALYTICS LAYER
64
65    - **Graphs Layout Improvements**: Improved performance graphs layout
66      for better readibility and maintenance: test grouping, axis
67      labels, descriptions, other informative decoration. Master report
68      generated. 744 graphs(!)
69
70
71    - **Performance Trending**: Further improvements of continuous
72      performance trending, anomaly detection and analysis.
