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. + - CSIT test environment is versioned, see + :ref:`test_environment_versioning`. - - **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. + - To identify performance changes due to VPP code changes from + v20.01.0 to v20.05.0, both have been tested in CSIT environment + ver. 4 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`. - - **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. +#. TEST FRAMEWORK - - **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. - -#. **Presentation and Analytics Layer** - - - **Performance trending**: Further improved continuous performance - trending with anomaly detection and analysis. - -#. **Test Framework Optimizations** + - **CSIT PAPI support**: Due to issues with PAPI performance, VAT is + still used in CSIT for all VPP scale tests. See known issues below. - **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>`_. - -.. 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/>`_. - -Skx vs. Hsw Comparison ----------------------- - -Relative performance comparison in measured NDR, PDR and MRR packet -throughput is calculated for tests executed on 3-Node Skylake (3n-skx) -and 3-Node Haswell (3n-hsw) physical testbed types in 1-core -configurations. - -NDR Comparison -~~~~~~~~~~~~~~ - -NDR comparison between testbed types is available in CSV and pretty -ASCII formats: - - - `CSV 1c NDR comparison <../_static/vpp/performance-compare-testbeds-3n-hsw-3n-skx-ndr.csv>`_, - - `ASCII 1c NDR comparison <../_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 RF result - files csit-vpp-perf-|srelease|-\*.zip - `archived here <../_static/archive/>`_. - -PDR Comparison -~~~~~~~~~~~~~~ - -PDR comparison between testbed types is available in CSV and pretty -ASCII formats: - - - `CSV 1c PDR comparison <../_static/vpp/performance-compare-testbeds-3n-hsw-3n-skx-pdr.csv>`_, - - `ASCII 1c PDR comparison <../_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 RF result - files csit-vpp-perf-|srelease|-\*.zip - `archived here <../_static/archive/>`_. - -MRR Comparison -~~~~~~~~~~~~~~ - -MRR comparison between testbed types is available in CSV and pretty -ASCII formats: - - - `CSV 1c MRR comparison <../_static/vpp/performance-compare-testbeds-3n-hsw-3n-skx-mrr.csv>`_, - - `ASCII 1c MRR comparison <../_static/vpp/performance-compare-testbeds-3n-hsw-3n-skx-mrr.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 RF result - files csit-vpp-perf-|srelease|-\*.zip - `archived here <../_static/archive/>`_. + removal of redundant RF keywords and aligning of suite/test + setup/teardowns. -Throughput Trending -------------------- +#.
