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. + - **BMRR Throughput**: MRR (Maximum Receive Rate) test code has been + updated with a configurable burst MRR parameters: trial duration + and number of trials in a single burst. Enables a new Burst MRR + (BMRR for short) methodology for more precise performance + trending. See updated :ref:`performance_test_methodology` section + for more details. - - **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. + - **2n-skx tests**: Added performamce tests for 2n-skx (2-Node Xeon + Skylake) testbeds: focus on baseline and scale tests, including + VM vhost and Container memif tests. - - **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. + - **3n-skx tests**: Added performamce tests for 3n-skx (3-Node Xeon + Skylake) testbeds: VM vhost and Container memif tests. - - **2-Node Tests**: A new baseline set of 2-node tests covering base - ip4, ip6, l2patch, l2bd, l2xc, running on new Xeon Skylake - testbeds. + - **VXLAN Scale Tests**: Added performamce tests for VXLAN scale with + dot1q and VPP L2BD. - - **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. + - **AVF Driver Tests**: Added performamce tests for i40e AVF driver + on VPP, no DPDK required. - - **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. + - **QAT**: Fixed reoccuring issues with QAT crypto accelerator cards. - - **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. + - **K8s/Ligato in Trending**: Added K8s/Ligato Container memif tests + to daily trending. -#. **Presentation and Analytics Layer** +#. TEST FRAMEWORK - - **Performance trending**: Further improved continuous performance - trending with anomaly detection and analysis. + - **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:`performance_test_methodology` section for more details. -#. **Test Framework Optimizations** + - **Trending Tests BMRR**: Used new Burst MRR (BMRR) tests for daily + trending. - - **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. The root causes behind poor -results repeatability vary between the test cases. - -NDR Changes -~~~~~~~~~~~ - -NDR throughput changes between releases are available in CSV and pretty -ASCII formats: - - - `CSV 1t1c NDR changes <../_static/vpp/performance-changes-1t1c-ndr.csv>`_, - - `CSV 2t2c NDR changes <../_static/vpp/performance-changes-2t2c-ndr.csv>`_, - - `ASCII 1t1c NDR changes <../_static/vpp/performance-changes-1t1c-ndr.txt>`_, - - `ASCII 2t2c NDR changes <../_static/vpp/performance-changes-2t2c-ndr.txt>`_. - -.. note:: - - Test results have been generated by - `FD.io test executor vpp performance job 3n-hsw`_, - with RF result - files csit-vpp-perf-|srelease|-\*.zip - `archived here <../_static/archive/>`_. - -PDR Changes -~~~~~~~~~~~ - -PDR throughput changes between releases are available in CSV and pretty -ASCII formats: - - - `CSV 1t1c PDR changes <../_static/vpp/performance-changes-1t1c-pdr.csv>`_, - - `CSV 2t2c PDR changes <../_static/vpp/performance-changes-2t2c-pdr.csv>`_, - - `ASCII 1t1c PDR changes <../_static/vpp/performance-changes-1t1c-pdr.txt>`_, - - `ASCII 2t2c PDR changes <../_static/vpp/performance-changes-2t2c-pdr.txt>`_. - -.. note:: - - Test results have been generated by - `FD.io test executor vpp performance job 3n-hsw`_, - with RF result - files csit-vpp-perf-|srelease|-\*.zip - `archived here <../_static/archive/>`_. - -MRR Changes -~~~~~~~~~~~ - -MRR throughput changes between releases are available in CSV and pretty -ASCII formats: - - - `CSV 1t1c MRR changes <../_static/vpp/performance-changes-1t1c-mrr.csv>`_, - - `CSV 2t2c MRR changes <../_static/vpp/performance-changes-2t2c-mrr.csv>`_, - - `CSV 4t4c MRR changes <../_static/vpp/performance-changes-4t4c-mrr.csv>`_, - - `ASCII 1t1c MRR changes <../_static/vpp/performance-changes-1t1c-mrr.txt>`_, - - `ASCII 2t2c MRR changes <../_static/vpp/performance-changes-2t2c-mrr.txt>`_, - - `ASCII 4t4c MRR changes <../_static/vpp/performance-changes-4t4c-mrr.txt>`_. + - **Per VPP Patch Performance Checks**: Per VPP gerrit patch vs. + parent performance tests, anomaly detection and no verify voting + (-1/0/+1) yet.
