VPP PERFORMANCE TESTS - - *MRR tests* - Maximum Receive Rate tests measure the packet forwarding rate - under the maximum load offered by traffic generator over a set trial - duration, regardless of packet loss. MRR tests are used for continuous - performance trending and for comparison between 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:`test_methodology` section + for more details. - - *MLR tests* - NDR and PDR tests measure the packet forwarding rate using - MLRsearch library by traffic generator. All tests that previously used - binary search were converted to MLRsearch. + - **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 L2patch, cross linking - 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* - Baseline set of 2-node tests covering base ip4, ip4, - l2patch, l2bd, l2xc. + - **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 multithreading* - SMT-aware automatic detection and - resource configuration including thread affinity, number of rx queues and - DPDK I/O mbufs. Tests are automatically tagged during execution indicating - configuration. + - **QAT**: Fixed reoccuring issues with QAT crypto accelerator cards. - - *Intel Skylake* - Topologies consisting of 2-node and 3-node using - SuperMirco servers each equipped with two Intel Xeon Skylake Platinum - processors. + - **VM Vhost Virtio Params Combinations**: Added performance tests + for VM vhost with different virtio parameters combinations: + indirect buffers, mergeable buffers. -#. **Presentation and Analytics Layer** + - **K8s/Ligato in Trending**: Added K8s/Ligato Container memif tests + to daily trending. - - *Performance trending* - Added continuous performance trending and - analysis. New Performance Trending and Performance Analysis jobs - executed regular throughput tests, with results being subsequently - analysed and trend and anomalies summarized and presented in VPP - Performance Dashboard and trendline graphs. +#. TEST FRAMEWORK -#. **Test Framework Optimizations** + - **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. - - *Performance tests efficiency* - Qemu build/install optimizations, - warmup phase handling, vpp restart handling. Resulted in improved - stability and reduced total execution time by 30% for single pkt - size e.g. 64B/78B. + - **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 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 -~~~~~~~~~~~ - -NDR throughput changes between releases are available in a -CSV and pretty ASCII formats: - - - `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>`_. - -.. note:: - - 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/>`_. - -PDR Changes -~~~~~~~~~~~ - -PDR throughput changes between releases are available in a -CSV and pretty ASCII formats: - - - `csv format for 1t1c <../_static/vpp/performance-changes-1t1c-pdr.csv>`_, - - `csv format for 2t2c <../_static/vpp/performance-changes-2t2c-pdr.csv>`_, - - `pretty ASCII format for 1t1c <../_static/vpp/performance-changes-1t1c-pdr.txt>`_, - - `pretty ASCII format for 2t2c <../_static/vpp/performance-changes-2t2c-pdr.txt>`_. - -.. note:: - - 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/>`_. + - **Per VPP Patch Performance Checks**: Per VPP gerrit patch vs. + parent performance tests, anomaly detection and no verify voting + (-1/0/+1) yet.
