-CSIT Release Notes\r
-==================\r
-\r
-Changes in CSIT |release|\r
--------------------------\r
-\r
-#. **Added VPP performance tests**\r
-\r
- - **MRR tests** : New MRR tests measure the packet forwarding rate\r
- under the maximum load offered by traffic generator over a set\r
- trial duration, regardless of packet loss. Maximum load for\r
- specified Ethernet frame size is set to the bi-directional link\r
- rate. MRR tests are used for continuous performance trending and\r
- for comparison between releases.\r
-\r
- - **Service Chaining with SRv6** : SRv6 (Segment Routing IPv6) proxy tests\r
- verifying performance of Endpoint to SR-unaware appliance via\r
- masquerading (End.AM), dynamic proxy (End.AD) or static proxy (End.AS)\r
- functions.\r
-\r
-#. **Presentation and Analytics Layer (PAL)**\r
-\r
- - Added continuous performance measuring, trending and anomaly\r
- detection. Includes new PAL code and Jenkins jobs for Performance\r
- Trending (PT) and Performance Analysis (PA) producing performance\r
- trending dashboard and trendline graphs with summary and drill-\r
- down views across all specified tests that can be reviewed and\r
- inspected regularly by FD.io developers and users community.\r
-\r
-#. **Test Framework Optimizations**\r
-\r
- - **Performance tests efficiency** : Qemu build/install\r
- optimizations, warmup phase handling, vpp restart handling.\r
- Resulted in improved stability and reduced total execution time by\r
- 30% for single pkt size e.g. 64B/78B.\r
-\r
- - **General code housekeeping** : ongoing RF keywords\r
- optimizations, removal of redundant RF keywords.\r
-\r
-Performance Changes\r
--------------------\r
-\r
-Relative performance changes in measured packet throughput in CSIT\r
-|release| are calculated against the results from CSIT |release-1|\r
-report. Listed mean and standard deviation values are computed based on\r
-a series of the same tests executed against respective VPP releases to\r
-verify test results repeatibility, with percentage change calculated for\r
-mean values. Note that the standard deviation is quite high for a small\r
-number of packet throughput tests, what indicates poor test results\r
-repeatability and makes the relative change of mean throughput value not\r
-fully representative for these tests. The root causes behind poor\r
-results repeatibility vary between the test cases.\r

+Release Notes
+=============
+
+Changes in |csit-release|
+-------------------------
+
+#. VPP PERFORMANCE TESTS
+
+ - **BMRR Throughput**: MRR (Maximum Receive Rate) test code has been
+ updated with a configurable burst MRR parameters: trial duration
+ and number of trials in a single burst. Enables a new Burst MRR
+ (BMRR for short) methodology for more precise performance
+ trending. See updated :ref:`test_methodology` section
+ for more details.
+
+ - **2n-skx tests**: Added performamce tests for 2n-skx (2-Node Xeon
+ Skylake) testbeds: focus on baseline and scale tests, including
+ VM vhost and Container memif tests.
+
+ - **3n-skx tests**: Added performamce tests for 3n-skx (3-Node Xeon
+ Skylake) testbeds: VM vhost and Container memif tests.
+
+ - **VXLAN Scale Tests**: Added performamce tests for VXLAN scale with
+ dot1q and VPP L2BD.
+
+ - **AVF Driver Tests**: Added performamce tests for i40e AVF driver
+ on VPP, no DPDK required.
+
+ - **QAT**: Fixed reoccuring issues with QAT crypto accelerator cards.
+
+ - **VM Vhost Virtio Params Combinations**: Added performance tests
+ for VM vhost with different virtio parameters combinations:
+ indirect buffers, mergeable buffers.
+
+ - **K8s/Ligato in Trending**: Added K8s/Ligato Container memif tests
+ to daily trending.
+
+#. TEST FRAMEWORK
+
+ - **Experimental Soak Tests**: Added performamce soak tests framework
+ code for extended time duration tests and throughput discovery
+ at given PLR and at give total test time e.g. minutes, hours,
+ days, weeks, months, years. See updated
+ :ref:`test_methodology` section for more details.
+
+ - **Trending Tests BMRR**: Used new Burst MRR (BMRR) tests for daily
+ trending.
+
+ - **Per VPP Patch Performance Checks**: Per VPP gerrit patch vs.
+ parent performance tests, anomaly detection and no verify voting
+ (-1/0/+1) yet. Manual trigger only. Not "marketed" to FD.io
+ community yet to avoid excessive LFN FD.io physical performance
+ testbed blocking.
+
+ - **Patch-on-Patch Infra**: Added capability to run performance tests
+ using CSIT gerrit patch code testing VPP gerrit patch code, i.e.
+ before any VPP and/or CSIT code is merged into git branch.
+
+ - **CSIT PAPI Support**: Initial implementation of PAPI L1 KWs in
+ CSIT using VPP Python bindings. Required for migraing away from
+ VAT. Very few L1 KWs implemented ("show version", "show
+ interfaces").
+
+ - **General Code Housekeeping**: Ongoing RF keywords optimizations,
+ removal of redundant RF keywords.
+
+#. PRESENTATION AND ANALYTICS LAYER
+
+ - **Graphs Layout Improvements**: Improved performance graphs layout
+ for better readibility and maintenance: test grouping, axis
+ labels, descriptions, other informative decoration. Master report
+ generated. 744 graphs(!)
+
+ - **Performance Trending**: Further improvements of continuous
+ performance trending, anomaly detection and analysis.
+
+#. MISCELLANEOUS
+
+ - **3n-dnv Tests (3rd Party)**: Published performance tests for 3n-
+ dnv (3-Node Atom Denverton) from 3rd party testbeds running FD.io
+ |csit-release| automated testing code.
+ Only graphs for Packet Throughput and Speedup Multi-core and not
+ for Packet Latency were published as there are no results for Packet
+ Latency available.
