VPP PERFORMANCE TESTS + + - **Service density 2n-skx tests**: Network Function Virtualization (NFV) + service density tests focus on measuring total per server throughput at + varied NFV service *packing* densities with vswitch providing host + dataplane. The goal is to compare and contrast performance of a shared + vswitch for different network topologies and virtualization technologies, + and their impact on vswitch performance and efficiency in a range of NFV + service configurations. + + - **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. + +#. TEST FRAMEWORK + + - **Container code optimizations**: Optimized container library allows to + run containre_memif tests faster. + + - **CSIT PAPI Support**: Continue converting existing VAT L1 keywords to + PAPI L1 KWs in CSIT using VPP Python bindings. Required for migrating away + from VAT. + + - **General Code Housekeeping**: Ongoing RF keywords optimizations, + removal of redundant RF keywords. + +#. PRESENTATION AND ANALYTICS LAYER + + - **Graphs Layout Improvements**: Improved performance graphs layout + for better readibility and maintenance: test grouping, axis + labels, descriptions, other informative decoration. + +#.
