-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
-calculated against the test results listed in CSIT |release-1| report. The\r
-comparison is calculated between the mean values based on collected and\r
-archived test results' samples for involved VPP releases. Standard deviation\r
-has been also listed for CSIT |release|. VPP-16.09 and VPP-17.01 numbers are\r
-provided for reference.\r

+Release Notes
+=============
+
+Changes in |csit-release|
+-------------------------
+
+#. VPP PERFORMANCE TESTS
+
+ - **Service density 2n-skx tests**: Added higher NF density tests with two
+ NFs' data-plane threads sharing a physical core. VPP IPv4 routing is now
+ used as a VNF payload similar to CNF tests.
+
+ - **Soak Tests**: Optimized 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. See updated
+ :ref:`test_methodology` section for more details.
+
+#. TEST FRAMEWORK
+
+ - **Qemu code refactor**: Complete code refactor of the key components of
+ QemuUtil.py and QemuManager.py (L1 and L2 KW counterparts). Added
+ implementation of kernel-image-kvm based VM replacing the previously used
+ NestedVM images. Added ability to run VPP as a payload in VNF.
+
+ - **CSIT PAPI Support**: Continued conversion of CSIT VAT L1 keywords to
+ PAPI L1 KWs in CSIT using VPP Python bindings. Redesign of key components
+ of PAPI Executor and PAPI history.
+
+ - **General Code Housekeeping**: Ongoing RF keywords optimizations,
+ removal of redundant RF keywords.
+
+ - **Test suite generator**: Added capability to generate suites for
+ different NIC models as well as throughput search algorithm types. Uses
+ base tests suites as source.
+
+ - **TOX verification**: Added verifications for test suite generator.
+
+#. 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
+
+ - **2n-dnv Tests (3rd Party)**: Published performance tests for 2n-
+ dnv (2-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.
