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**: Network Function Virtualization (NFV) + service density tests focus on measuring total per server throughput at + varied NFV service *packing* densities with vswitch providing host + dataplane. The goal is to compare and contrast performance of a shared + vswitch for different network topologies and virtualization technologies, + and their impact on vswitch performance and efficiency in a range of NFV + service configurations. -#. PRESENTATION AND ANALYTICS LAYER + - **Experimental Soak Tests**: Added performamce soak tests framework + code for extended time duration tests and throughput discovery + at given PLR and at give total test time e.g. minutes, hours, + days, weeks, months, years. See updated + :ref:`test_methodology` section for more details. + +#. TEST FRAMEWORK - - **Performance trending**: Further improvements of continuous - performance trending, anomaly detection and analysis. + - **Container code optimizations**: Optimized container library allows to + run containre_memif tests faster. -#. TEST FRAMEWORK OPTIMIZATIONS + - **CSIT PAPI Support**: Continue converting existing VAT L1 keywords to + PAPI L1 KWs in CSIT using VPP Python bindings. Required for migrating away + from VAT. - **General Code Housekeeping**: Ongoing RF keywords optimizations, removal of redundant RF keywords. +#. PRESENTATION AND ANALYTICS LAYER + + - **Graphs Layout Improvements**: Improved performance graphs layout + for better readibility and maintenance: test grouping, axis + labels, descriptions, other informative decoration. + +#. MISCELLANEOUS + + - **3n-dnv Tests (3rd Party)**: Published performance tests for 3n- + dnv (3-Node Atom Denverton) from 3rd party testbeds running FD.io + |csit-release| automated testing code. + Only graphs for Packet Throughput and Speedup Multi-core and not + for Packet Latency were published as there are no results for Packet + Latency available. + .. raw:: latex \clearpage @@ -71,40 +64,18 @@ List of known issues in |csit-release| for VPP performance tests: | 1 | `CSIT-570 | Sporadic (1 in 200) NDR discovery test failures on x520.
