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. + - **Enhanced and added VPP hoststack tests** to daily and weekly + trending including: Quic VPP Echo, UDP+TCP LD_PRELOAD iPerf3, + LD_PRELOAD NGINX. -#. TEST FRAMEWORK + - **Added Nvidia/Mellanox DPDK tests** to daily and weekly trending + and report, in addition to RDMA_CORE ones that were already + there. + + - **Jumbo frames tests** got fixed and re-added number of to report + coverage tests. - - **Removed ASTF PPS tests**: They provide no real benefit - compared to TPUT tests. The ip4base variants renamed to TPUT. + - **Intel Xeon SKX performance testbeds** got decommissioned and + removed from FD.io performance lab. - - **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. +#. TEST FRAMEWORK - - **CSIT test environment** version has been updated to ver. 10, see - :ref:`test_environment_versioning`. + - **CSIT test environment** version has not changed from ver. 11 used + in previous release, 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`. + - **CSIT PAPI optimizations for scale** got applied improving PAPI + programming speed especially for large scale tests. VAT has been + now completely deprecated from CSIT. - **General Code Housekeeping**: Ongoing code optimizations and bug fixes. #. PRESENTATION AND ANALYTICS LAYER - - **Graphs improvements**: Updated Packet Latency graphs, - see :ref:`latency_methodology`. + - `Performance dashboard `_ got updated with + addition of VPP telemetry trending across all VPP tests. A number + of code and AWS resource usage optimizations got applied to the + data processing pipeline and UI frontend and backend. + + - Examples of release iterative data visualisation: + + - `Packet throughput 2n-icx-e810cq-ip4-base-scale-pdr `_ + -
