.. _vpp_performance_tests_release_notes: Release Notes ============= Changes in |csit-release| ------------------------- #. VPP PERFORMANCE TESTS - **Enhanced and added VPP hoststack tests** to daily and weekly trending including: Quic VPP Echo, UDP+TCP LD_PRELOAD iPerf3, LD_PRELOAD NGINX. - **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. - **Intel Xeon SKX performance testbeds** got decommissioned and removed from FD.io performance lab. #. TEST FRAMEWORK - **CSIT test environment** version has not changed from ver. 11 used in previous release, see :ref:`test_environment_versioning`. - **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 - `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 `_ - `Speedup Multi-Core throughput graph for 2n-icx-e810cq-ip4-base-pdr `_ - `MRR, NDR and PDR comparison for 2n-icx-e810cq-ip4-base `_ - `Normalized throughput architecture comparison for 2n-[icx|clx]-e810cq-ip4-base-pdr `_ - `NICs comparison for 2n-icx-ip4-base-pdr `_ .. raw:: latex \clearpage .. _vpp_known_issues: Known Issues ------------ New ___ +----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+ | #
