VPP PERFORMANCE TESTS - - **MRR Throughput**: MRR (Maximum Receive Rate) test code has now - configurable trial duration and number of consecutive executions. - Coverage of MRR tests has been extended across more test - scenarios. 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. + - **Enhanced and added VPP hoststack tests** to daily and weekly + trending including: Quic VPP Echo, UDP+TCP LD_PRELOAD iPerf3, + LD_PRELOAD NGINX. + + - **Added Nvidia/Mellanox DPDK tests** to daily and weekly trending + and report, in addition to RDMA_CORE ones that were already + there. + + - **Jumbo frames tests** got fixed and re-added number of to report + coverage tests. + + - **Intel Xeon SKX performance testbeds** got decommissioned and + removed from FD.io performance lab. + +#. TEST FRAMEWORK + + - **CSIT test environment** version has not changed from ver. 11 used + in previous release, see :ref:`test_environment_versioning`. + + - **CSIT PAPI optimizations for scale** got applied improving PAPI + programming speed especially for large scale tests. VAT has been + now completely deprecated from CSIT. + + - **General Code Housekeeping**: Ongoing code optimizations and bug + fixes. #. PRESENTATION AND ANALYTICS LAYER - - **Performance trending**: Further improvements of continuous - performance trending, anomaly detection and analysis. + - `Performance dashboard `_ got updated with + addition of VPP telemetry trending across all VPP tests. A number + of code and AWS resource usage optimizations got applied to the + data processing pipeline and UI frontend and backend. -#.
