-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.
