VPP PERFORMANCE TESTS - - - **Reduction of tests**: Removed certain test variations executed - iteratively for the report (as well as in daily and weekly - trending) due to physical testbeds overload. - -#. TEST FRAMEWORK - - - **Removed ASTF PPS tests**: They provide no real benefit - compared to TPUT tests. The ip4base variants renamed to TPUT. - - - **Changed TCP TPUT profiles**: The previous ones were found to be faulty. - The new ones do not use bursts of packets to avoid CSIT-1830 and CSIT-1846. - - - **CSIT test environment** version has been updated to ver. 10, see - :ref:`test_environment_versioning`. - - - **CSIT PAPI support**: Due to issues with PAPI performance, and - deprecation of VAT, VPP CLI is used in CSIT for many VPP scale - tests. See :ref:`vpp_known_issues`. - - - **General Code Housekeeping**: Ongoing code optimizations and bug - fixes. - -#. PRESENTATION AND ANALYTICS LAYER - - - **Graphs improvements**: Updated Packet Latency graphs, - see :ref:`latency_methodology`. - -.. raw:: latex - - \clearpage - -.. _vpp_known_issues: - -Known Issues ------------- -
