MRR tests are used for continuous performance trending + and for comparison between VPP releases. + + - **MLRsearch Throughput**: MLRsearch algorithm has been introduced + for all NDR and PDR throughput tests. All tests that previously + used binary search got converted to MLRsearch. Coverage of NDR/PDR + tests has been extended across more test scenarios. + + - **L2patch Tests**: Tests measure performance of VPP L2patch, the + fastest L2 forwarding path implemented in VPP, that cross-links + RX and TX of two physical interfaces. + + - **2-Node Tests**: A new baseline set of 2-node tests covering base + ip4, ip6, l2patch, l2bd, l2xc, running on new Xeon Skylake + testbeds. + + - **Generated tests**: Simplified and unified test structure, semi- + autogenerated by generator script. Test generator is currently + able to create test combinations with various frame size and + cores combinations. All existing test cases were converted to new + format. + + - **Simultaneous Multi-Threading**: SMT-aware detection of server + processor operation mode (HyperThreading enabled/disabled) with + associated compute resource configuration including thread + affinity, number of Rx queues and DPDK I/O mbufs. Tests are + automatically tagged during execution to indicate executed thread + configuration. + + - **Intel Xeon Skylake Support**: Support for 2-Node and 3-Node + physical testbed topologies based on the new SuperMirco servers + each with two Intel Xeon Skylake Platinum processors. Full + Ansible playbooks refactor for quick server (re)installation and + reference pointers of configuration. + +#. **Presentation and Analytics Layer** + + - **Performance trending**: Further improved continuous performance + trending with anomaly detection and analysis. + +#. **Test Framework Optimizations** + + - **General Code Housekeeping**: Ongoing RF keywords optimizations, + removal of redundant RF keywords. + +Performance Changes +------------------- + +Relative performance changes in measured NDR, PDR and MRR packet +throughput in |csit-release| are calculated against the test results +from |csit-release-1| report, for tests running on 3-Node Intel Xeon +Haswell testbeds (3n-hsw) in 1-core, 2-core and 4-core (MRR only) +configurations. + +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 repeatability, 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.
