4 Changes in |csit-release|
5 -------------------------
7 #. VPP PERFORMANCE TESTS
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
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.
20 - **3n-skx tests**: Added performamce tests for 3n-skx (3-Node Xeon
21 Skylake) testbeds: VM vhost and Container memif tests.
23 - **VXLAN Scale Tests**: Added performamce tests for VXLAN scale with
26 - **AVF Driver Tests**: Added performamce tests for i40e AVF driver
27 on VPP, no DPDK required.
29 - **QAT**: Fixed reoccuring issues with QAT crypto accelerator cards.
31 - **K8s/Ligato in Trending**: Added K8s/Ligato Container memif tests
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.
42 - **Trending Tests BMRR**: Used new Burst MRR (BMRR) tests for daily
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
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.
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
60 - **General Code Housekeeping**: Ongoing RF keywords optimizations,
61 removal of redundant RF keywords.
63 #. PRESENTATION AND ANALYTICS LAYER
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(!)
71 - **Performance Trending**: Further improvements of continuous
72 performance trending, anomaly detection and analysis.
