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. + - **Service density 2n-skx tests**: Added higher NF density tests with + IPSec encencryption between DUTs. -#. PRESENTATION AND ANALYTICS LAYER + - **AVF tests**: Full test coveraged based on code changes in CSIT core + layer (driver/interface awareness) and generated by suite generator + (Fortville NICs only). + + - **Hoststack TCP/IP tests**: Major refactor of Hoststack TCP + performance tests using WRK generator talking to the VPP HTTP + static server plugin measuring connections per second and + requests per second. - - **Performance trending**: Further improvements of continuous - performance trending, anomaly detection and analysis. +#. TEST FRAMEWORK -#. TEST FRAMEWORK OPTIMIZATIONS + - **CSIT Python3 Support**: Full migration of CSIT from Python2.7 to + Python3.6. This change includes library migration, PIP dependency upgrade, + CSIT container images, infrastructure packages ugrade/installation. + + - **CSIT PAPI Support**: Finished conversion of CSIT VAT L1 keywords + to PAPI L1 KWs in CSIT using VPP Python bindings (VPP PAPI). + Redesign of key components of PAPI Socket Executor and PAPI + history. Due to issues with PAPI performance, VAT is still used + in CSIT for all VPP scale tests. See known issues below. - **General Code Housekeeping**: Ongoing RF keywords optimizations, - removal of redundant RF keywords. + removal of redundant RF keywords and aligning of suite/test + setup/teardowns. + + +#. PRESENTATION AND ANALYTICS LAYER + + - **Graphs Layout Improvements**: Improved performance graphs layout + for better readibility and maintenance: test grouping, axis + labels, descriptions, other informative decoration. .. raw:: latex @@ -65,46 +52,31 @@ Known Issues List of known issues in |csit-release| for VPP performance tests: -+----+-----------------------------------------+---------------------------------------------------------------------------------------------------------------------------------+ -| # | JiraID | Issue Description | -+====+=========================================+=================================================================================================================================+ -| 1 | `CSIT-570 | Sporadic (1 in 200) NDR discovery test failures on x520.
