-Known Issues - to be updated\r
-------------\r
+   - *MRR tests* - New Maximum Receive Rate tests measure the packet\r
+     forwarding rate under the maximum load offered by traffic\r
+     generator over a set trial duration, regardless of packet loss.\r
+     MRR tests are used for continuous performance trending and for\r
+     comparison between releases.\r
+\r
+   - *Service Chaining with SRv6* - New SRv6 (Segment Routing IPv6) proxy\r
+     tests measure performance of SRv6 Endpoint fronting SR-unaware\r
+     appliance via masquerading (End.AM), dynamic proxy (End.AD) or\r
+     static proxy (End.AS) SR functions.\r
+\r
+#. **Presentation and Analytics Layer**\r
+\r
+   - *Performance trending* - Added continuous performance trending and\r
+     analysis. New Performance Trending and Performance Analysis jobs\r
+     executed regular throughput tests, with results being subsequently\r
+     analysed and trend and anomalies summarized and presented in VPP\r
+     Performance Dashboard and trendline graphs.\r
+\r
+#. **Test Framework Optimizations**\r
+\r
+   - *Performance tests efficiency* - Qemu build/install optimizations,\r
+     warmup phase handling, vpp restart handling. Resulted in improved\r
+     stability and reduced total execution time by 30% for single pkt\r
+     size e.g. 64B/78B.\r
+\r
+   - *General code housekeeping* - ongoing RF keywords optimizations,\r
+     removal of redundant RF keywords.\r
+\r
+Performance Changes\r
+-------------------\r
+\r
+Relative performance changes in measured packet throughput in CSIT\r
+|release| are calculated against the results from CSIT |release-1|\r
+report. Listed mean and standard deviation values are computed based on\r
+a series of the same tests executed against respective VPP releases to\r
+verify test results repeatibility, with percentage change calculated for\r
+mean values. Note that the standard deviation is quite high for a small\r
+number of packet throughput tests, what indicates poor test results\r
+repeatability and makes the relative change of mean throughput value not\r
+fully representative for these tests. The root causes behind poor\r
+results repeatibility vary between the test cases.\r
