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. + - **Service density 2n-skx tests**: Added higher NF density tests with two + NFs' data-plane threads sharing a physical core. VPP IPv4 routing is now + used as a VNF payload similar to CNF tests. - - *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. + - **Soak Tests**: Optimized 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. See updated + :ref:`test_methodology` section for more details. - - *L2patch tests* - Tests measure performance of L2patch, cross linking - RX and TX of two physical interfaces. +#. TEST FRAMEWORK - - *2-node tests* - Baseline set of 2-node tests covering base ip4, ip4, - l2patch, l2bd, l2xc. + - **Qemu code refactor**: Complete code refactor of the key components of + QemuUtil.py and QemuManager.py (L1 and L2 KW counterparts). Added + implementation of kernel-image-kvm based VM replacing the previously used + NestedVM images. Added ability to run VPP as a payload in VNF. - - *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. + - **CSIT PAPI Support**: Continued conversion of CSIT VAT L1 keywords to + PAPI L1 KWs in CSIT using VPP Python bindings. Redesign of key components + of PAPI Executor and PAPI history. - - *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. - - - *Intel Skylake* - Topologies consisting of 2-node and 3-node using - SuperMirco servers each equipped with two Intel Xeon Skylake Platinum - processors. - -#. **Presentation and Analytics Layer** - - - *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 Optimizations** - - - *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. - - - *General code housekeeping* - ongoing RF keywords optimizations, + - **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/>`_. - -MRR Changes -~~~~~~~~~~~ - -MRR small packet throughput changes between releases are available in a -CSV and pretty ASCII formats: - - - `csv format for 1t1c <../_static/vpp/performance-changes-1t1c-mrr.csv>`_, - - `csv format for 2t2c <../_static/vpp/performance-changes-2t2c-mrr.csv>`_, - - `csv format for 4t4c <../_static/vpp/performance-changes-4t4c-mrr.csv>`_, - - `pretty ASCII format for 1t1c <../_static/vpp/performance-changes-1t1c-mrr.txt>`_, - - `pretty ASCII format for 2t2c <../_static/vpp/performance-changes-2t2c-mrr.txt>`_, - - `pretty ASCII format for 4t4c <../_static/vpp/performance-changes-4t4c-mrr.txt>`_. - -.. note:: - - Test results have been generated by - `FD.io test executor vpp mrr jobs `_ - with Robot Framework result files csit-vpp-perf-mrr-daily-master__*__output.xml.gz - `archived here `_. - -Comparison Across Testbeds --------------------------- - -Relative performance changes in measured packet throughputon 3-Node Skx testbed -are calculated against the results measured on 3-Node Hsw testbed. - -NDR Changes -~~~~~~~~~~~ - -NDR changes between testbeds are available in a -CSV and pretty ASCII formats: - - - `csv format for ndr <../_static/vpp/performance-compare-testbeds-3n-hsw-3n-skx-ndr.csv>`_, - - `pretty ASCII format for ndr <../_static/vpp/performance-compare-testbeds-3n-hsw-3n-skx-ndr.txt>`_. - -.. note:: - - Test results have been generated by - `FD.io test executor vpp performance job 3n-hsw`_ and - `FD.io test executor vpp performance job 3n-skx`_ - with Robot Framework result - files csit-vpp-perf-|srelease|-\*.zip - `archived here <../_static/archive/>`_. - -PDR Changes -~~~~~~~~~~~ - -PDR throughput changes between testbeds are available in a -CSV and pretty ASCII formats: - - - `csv format for pdr <../_static/vpp/performance-compare-testbeds-3n-hsw-3n-skx-pdr.csv>`_, - - `pretty ASCII format for pdr <../_static/vpp/performance-compare-testbeds-3n-hsw-3n-skx-pdr.txt>`_. - -.. note:: - - Test results have been generated by - `FD.io test executor vpp performance job 3n-hsw`_ and - `FD.io test executor vpp performance job 3n-skx`_ - with Robot Framework result - files csit-vpp-perf-|srelease|-\*.zip - `archived here <../_static/archive/>`_. - -MRR Changes -~~~~~~~~~~~ - -MRR throughput changes between testbeds are available in a -CSV and pretty ASCII formats: + - **Test suite generator**: Added capability to generate suites for + different NIC models as well as throughput search algorithm types.
