-CSIT Release Notes\r
-==================\r
-\r
-Changes in CSIT |release|\r
--------------------------\r
-\r
-#. VPP performance test environment changes\r
-\r
-   - Further optimizations of VM and vhost-user test environment - various\r
-     Qemu virtio queue size testing with value of 256 and 1024. Applied\r
-     Linux CFS optimization to run VPP worker threads and Qemu worker threads\r
-     with highest priority.\r
-\r
-#. VPP performance test framework changes\r
-\r
-   - Full code review, optimization and refactor.\r
-\r
-#. T-rex changes\r
-\r
-   - Full refactor of T-rex driver and introduce of traffic profiles that\r
-     improves readability, manageability of traffic profiles for various\r
-     test scenarios.\r
-\r
-#. Added VPP performance tests\r
-\r
-   - **LXC memif**\r
-\r
-     - Memif interface tests interconnecting two VPP instances on single SUT.\r
-       Master VPP instance running on native OS with Intel x520 NIC and guest\r
-       VPP instance running in Linux Container (LXC) doing the L2 cross\r
-       connect loop. LXC running in privileged mode is pinned to dedicated\r
-       cores. All VPP instances are same version.\r
-\r
-   - **Stateful Security Groups**\r
-\r
-   - **VM vhost use cases**\r
-\r
-Performance Improvements\r
-------------------------\r
-\r
-Substantial improvements in measured packet throughput have been\r
-observed in a number of CSIT |release| tests listed below, with relative\r
-increase  of double-digit percentage points. Relative improvements are\r
-calculated against the test results listed in CSIT |release-1| report.\r
-VPP-16.09 numbers are provided for reference.\r

+=============
+
+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.
