Presentation and Analytics Layer - - - Added throughput speedup analysis for multi-core and multi-thread - VPP tests into Presentation and Analytics Layer (PAL) for automated - CSIT test results analysis; - -#.

VPP PERFORMANCE TESTS + + - **Service density 2n-skx tests**: Added higher NF density tests with + IPSec encencryption between DUTs. + + - **AVF tests**: Full test coveraged based on code changes in CSIT core + layer (driver/interface awareness) and generated by suite generator + (Fortville NICs only). + + - **Hoststack TCP/IP tests**: Major refactor of Hoststack TCP + performance tests using WRK generator talking to the VPP HTTP + static server plugin measuring connections per second and + requests per second. + +#. TEST FRAMEWORK + + - **CSIT Python3 Support**: Full migration of CSIT from Python2.7 to + Python3.6. This change includes library migration, PIP dependency upgrade, + CSIT container images, infrastructure packages ugrade/installation. + + - **CSIT PAPI Support**: Finished conversion of CSIT VAT L1 keywords + to PAPI L1 KWs in CSIT using VPP Python bindings (VPP PAPI). + Redesign of key components of PAPI Socket Executor and PAPI + history. 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 and aligning of suite/test + setup/teardowns. + + +#. PRESENTATION AND ANALYTICS LAYER + + - **Graphs Layout Improvements**: Improved performance graphs layout + for better readibility and maintenance: test grouping, axis + labels, descriptions, other informative decoration. + +.. raw:: latex + + \clearpage + +.. _vpp_known_issues: + +Known Issues +------------ + +List of known issues in |csit-release| for VPP performance tests: + ++----+-----------------------------------------+----------------------------------------------------------------------------------------------------------+ +| # | JiraID | Issue Description | ++====+=========================================+==========================================================================================================+ +| 1 | `CSIT-570 | Sporadic (1 in 200) NDR discovery test failures on x520.
