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.

TEST FRAMEWORK + - 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.
