+Release Notes
+=============
+
+Changes in |csit-release|
+-------------------------
+
+#. **VPP Performance Tests**
+
+ - **MRR Throughput**: MRR (Maximum Receive Rate) test code has now
+ configurable trial duration and number of consecutive executions.
+ Coverage of MRR tests has been extended across more test
+ scenarios. MRR tests are used for continuous performance trending
+ and for comparison between VPP releases.
+
+ - **MLRsearch Throughput**: MLRsearch algorithm has been introduced
+ for all NDR and PDR throughput tests. All tests that previously
+ used binary search got converted to MLRsearch. Coverage of NDR/PDR
+ tests has been extended across more test scenarios.
+
+ - **L2patch Tests**: Tests measure performance of VPP L2patch, the
+ fastest L2 forwarding path implemented in VPP, that cross-links
+ RX and TX of two physical interfaces.
+
+ - **2-Node Tests**: A new baseline set of 2-node tests covering base
+ ip4, ip6, l2patch, l2bd, l2xc, running on new Xeon Skylake
+ testbeds.
+
+ - **Generated tests**: Simplified and unified test structure, semi-
+ autogenerated by generator script. Test generator is currently
+ able to create test combinations with various frame size and
+ cores combinations. All existing test cases were converted to new
+ format.
+
+ - **Simultaneous Multi-Threading**: SMT-aware detection of server
+ processor operation mode (HyperThreading enabled/disabled) with
+ associated compute resource configuration including thread
+ affinity, number of Rx queues and DPDK I/O mbufs. Tests are
+ automatically tagged during execution to indicate executed thread
+ configuration.
+
+ - **Intel Xeon Skylake Support**: Support for 2-Node and 3-Node
+ physical testbed topologies based on the new SuperMirco servers
+ each with two Intel Xeon Skylake Platinum processors. Full
+ Ansible playbooks refactor for quick server (re)installation and
+ reference pointers of configuration.
+
+#. **Presentation and Analytics Layer**
+
+ - **Performance trending**: Further improved continuous performance
+ trending with anomaly detection and analysis.
+
+#. **Test Framework Optimizations**
+
+ - **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 repeatability, 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 repeatability 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.
+
+Known Issues
+------------
+
+List of known issues in |csit-release| for VPP performance tests:
+
++---+-------------------------------------------------+------------+-----------------------------------------------------------------+
+| # | Issue | Jira ID | Description |
++===+=================================================+============+=================================================================+
+| 1 | Sporadic (1 in 200) NDR discovery test failures | CSIT-570 | DPDK reporting rx-errors, indicating L1 issue. Suspected issue |
+| | on x520. | | with HW combination of X710-X520 in LF testbeds. Not observed |
+| | | | outside of LF testbeds. |
++---+-------------------------------------------------+------------+-----------------------------------------------------------------+
+| 2 | High failure rate of api call | VPP-1361 | Failure rate: 30-40% of tests failing due to interfaces not |
+| | sw_interface_set_flags [admin-up|link-up] | | in link-up state after API call sw_interface_set_flags. |
++---+-------------------------------------------------+------------+-----------------------------------------------------------------+
+| 3 | Scale IPSecHW Interface mode throughput | CSIT-1234 | IPSec throughput regression: NDR -28%..-31%, PDR -28%..-31%, |
+| | regression. | | MRR -40%. Affects IPSec HW Scale 1000tnl tests with Int mode. |
