-Performance Improvements\r
-------------------------\r
-\r
-Substantial improvements in measured packet throughput have been observed in a\r
-number of CSIT |release| tests listed below, with relative increase of\r
-double-digit percentage points. Relative improvements for this release are\r

+Release Notes
+=============
+
+Changes in |csit-release|
+-------------------------
+
+#. VPP PERFORMANCE TESTS
+
+ - **Service density 2n-skx tests**: Network Function Virtualization (NFV)
+ service density tests focus on measuring total per server throughput at
+ varied NFV service *packing* densities with vswitch providing host
+ dataplane. The goal is to compare and contrast performance of a shared
+ vswitch for different network topologies and virtualization technologies,
+ and their impact on vswitch performance and efficiency in a range of NFV
+ service configurations.
+
+ - **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.
+
+#. TEST FRAMEWORK
+
+ - **Container code optimizations**: Optimized container library allows to
+ run containre_memif tests faster.
+
+ - **CSIT PAPI Support**: Continue converting existing VAT L1 keywords to
+ PAPI L1 KWs in CSIT using VPP Python bindings. Required for migrating away
+ from VAT.
+
+ - **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.
+
+#. 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.
