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. +#. VPP PERFORMANCE TESTS -#. **Presentation and Analytics Layer** + - CSIT test environment is versioned, see + :ref:`test_environment_versioning`. - - **Performance trending**: Further improved continuous performance - trending with anomaly detection and analysis. - -#. **Test Framework Optimizations** + - To identify performance changes due to VPP code changes from + v20.05.0 to v20.09.0, both have been tested in CSIT environment + ver. 5 and compared against each other. All substantial + progressions has been marked up with RCA analysis. See + :ref:`vpp_compare_current_vs_previous_release` and + :ref:`vpp_known_issues`. - - **General Code Housekeeping**: Ongoing RF keywords optimizations, - removal of redundant RF keywords. + - **NAT44 tests**: Adapted existing and added new tests. -Performance Changes -------------------- + - Refactored NAT44 deterministic mode (nat44det) tests to use separate + det44 vpp plugin and to use the same scheme of inside and outside + addresses and ports, as used in new NAT44 endpoint-dependent mode tests. -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 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. The root causes behind poor -results repeatability vary between the test cases. - -NDR Changes -~~~~~~~~~~~ + - Added new NAT44 endpoint-depended mode uni-directional (nat44ed-udir) + tests that measure packet throughput in one direction with usage of TRex + in stateless mode. -NDR throughput changes between releases are available in a -CSV and pretty ASCII formats: + - Added new NAT44 endpoint-dependent mode CPS tests that measure + connections per second with usage of TRex in stateful mode. + NOTE: CPS measurement data will be added in two weeks. - - `csv format for 1t1c <../_static/vpp/performance-changes-1t1c-ndr.csv>`_, - - `csv format for 2t2c <../_static/vpp/performance-changes-2t2c-ndr.csv>`_, - - `pretty ASCII format for 1t1c <../_static/vpp/performance-changes-1t1c-ndr.txt>`_, - - `pretty ASCII format for 2t2c <../_static/vpp/performance-changes-2t2c-ndr.txt>`_. + - **IPSec async mode tests**: Added VPP performance tests for async crypto + engine. -.. note:: + - **AMD 2n-zn2 testbed**: New physical testbed type installed in FD.io CSIT, + VPP performance data will be added in upcoming weeks. - Test results have been generated by - `FD.io test executor vpp performance job 3n-hsw`_, - with Robot Framework result - files csit-vpp-perf-|srelease|-\*.zip - `archived here <../_static/archive/>`_. +#.
