Changes in CSIT |release|\r
-------------------------\r
\r
-#. VPP performance test environment changes\r
+#. **VPP performance tests**\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
+ - *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
-#. VPP performance test framework changes\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
- - Full code review, optimization and refactor.\r
+#. **Presentation and Analytics Layer**\r
\r
-#. T-rex changes\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
- - 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
+#. **Test Framework Optimizations**\r
\r
-#. Added VPP performance tests\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
- - **LXC memif**\r
+ - *General code housekeeping* - ongoing RF keywords optimizations,\r
+ removal of redundant RF keywords.\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
+Performance Changes\r
+-------------------\r
\r
- - **Stateful Security Groups**\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
