-\r
- - **Linux Container VPP memif virtual interface tests**\r
-\r

+CSIT Release Notes
+==================
+
+Changes in CSIT |release|
+-------------------------
+
+#. **VPP performance tests**
+
+ - *MRR tests* - New Maximum Receive Rate tests measure the packet
+ forwarding rate under the maximum load offered by traffic
+ generator over a set trial duration, regardless of packet loss.
+ MRR tests are used for continuous performance trending and for
+ comparison between releases.
+
+ - *Service Chaining with SRv6* - New SRv6 (Segment Routing IPv6) proxy
+ tests measure performance of SRv6 Endpoint fronting SR-unaware
+ appliance via masquerading (End.AM), dynamic proxy (End.AD) or
+ static proxy (End.AS) SR functions.
+
+#. **Presentation and Analytics Layer**
+
+ - *Performance trending* - Added continuous performance trending and
+ analysis. New Performance Trending and Performance Analysis jobs
+ executed regular throughput tests, with results being subsequently
+ analysed and trend and anomalies summarized and presented in VPP
+ Performance Dashboard and trendline graphs.
+
+#. **Test Framework Optimizations**
+
+ - *Performance tests efficiency* - Qemu build/install optimizations,
+ warmup phase handling, vpp restart handling. Resulted in improved
+ stability and reduced total execution time by 30% for single pkt
+ size e.g. 64B/78B.
+
+ - *General code housekeeping* - ongoing RF keywords optimizations,
+ removal of redundant RF keywords.
+
+Performance Changes
+-------------------
+
+Relative performance changes in measured packet throughput in CSIT
+|release| are calculated against the results from CSIT |release-1|
+report. Listed mean and standard deviation values are computed based on
+a series of the same tests executed against respective VPP releases to
+verify test results repeatibility, with percentage change calculated for
+mean values. Note that the standard deviation is quite high for a small
+number of packet throughput tests, what indicates poor test results
+repeatability and makes the relative change of mean throughput value not
+fully representative for these tests. The root causes behind poor
+results repeatibility vary between the test cases.

+Throughput Trending
+-------------------
+
+In addition to reporting throughput changes between VPP releases, CSIT
+provides continuous performance trending for VPP master branch:
+
+#. `VPP Performance Dashboard <https://docs.fd.io/csit/master/trending/introduction/index.html>`_
+ - per VPP test case throughput trend, trend compliance and summary of
+ detected anomalies.
+
+#. `Trending Methodology <https://docs.fd.io/csit/master/trending/methodology/index.html>`_
+ - throughput test metrics, trend calculations and anomaly
+ classification (progression, regression, outlier).
+
+#. `Trendline Graphs <https://docs.fd.io/csit/master/trending/trending/index.html>`_
+ - per VPP build MRR throughput measurements against the trendline
+ with anomaly highlights, with associated CSIT test jobs.
