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** + - **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. - - **Performance trending**: Further improved continuous performance - trending with anomaly detection and analysis. - -#. **Test Framework Optimizations** + - **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. - - **General Code Housekeeping**: Ongoing RF keywords optimizations, - removal of redundant RF keywords. +#. TEST FRAMEWORK -Performance Changes -------------------- + - **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. -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 -~~~~~~~~~~~ + - **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. -NDR throughput changes between releases are available in a -CSV and pretty ASCII formats: + - **General Code Housekeeping**: Ongoing RF keywords optimizations, + removal of redundant RF keywords. - - `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>`_. + - **Test suite generator**: Added capability to generate suites for + different NIC models as well as throughput search algorithm types.
