-Known Issues - to be updated +#. **Added VPP performance tests** + + - **MRR tests** : New MRR tests measure the packet forwarding rate + under the maximum load offered by traffic generator over a set + trial duration, regardless of packet loss. Maximum load for + specified Ethernet frame size is set to the bi-directional link + rate. MRR tests are used for continuous performance trending and + for comparison between releases. + + - **Service Chaining with SRv6** : SRv6 (Segment Routing IPv6) proxy tests + verifying performance of Endpoint to SR-unaware appliance via + masquerading (End.AM), dynamic proxy (End.AD) or static proxy (End.AS) + functions. + +#. **Presentation and Analytics Layer (PAL)** + + - Added continuous performance measuring, trending and anomaly + detection. Includes new PAL code and Jenkins jobs for Performance + Trending (PT) and Performance Analysis (PA) producing performance + trending dashboard and trendline graphs with summary and drill- + down views across all specified tests that can be reviewed and + inspected regularly by FD.io developers and users community. + +#. **Test Framework Optimizations** + + - **Performance tests efficiency** : Qemu build/install + optimizations, warmup phase handling, vpp restart handling. + Resulted in improved stability and reduced total execution time by + 30% for single pkt size e.g. 64B/78B. + + - **General code housekeeping** : ongoing RF keywords + optimizations, removal of redundant RF keywords. + +Performance Changes +------------------- + +Relative performance changes in measured packet throughput in CSIT +|release| are calculated against the results from CSIT |release-1| +report. Listed mean and standard deviation values are computed based on +a series of the same tests executed against respective VPP releases to +verify test results repeatibility, with percentage change calculated for +mean values. Note that the standard deviation is quite high for a small +number of packet throughput tests, what indicates poor test results +repeatability and makes the relative change of mean throughput value not +fully representative for these tests.
