Hi Stanislav, You are welcome.
Thanks for spotting, and you are right, the af_xdp driver numbers did a nose dive indeed. It’s visible on xeon skylake per your link references, and also on: - intel xeon cascadelake [2], [3], - arm thunderx2 [4]. Comparison tables [5], [6] provide a proof that the drop is due to CSIT test environment change from v7 to v8 [7], and unlikely due to VPP code. We need to investigate. Hope this makes sense.

Many thanks to all contributors in CSIT and VPP communities for making it happen. See below for CSIT-2110 release summary and pointers to specific sections in the report. Welcome all comments, best by email to csit-...@lists.fd.io<mailto:csit-...@lists.fd.io>. Tibor CSIT-2110 Release Summary ------------------------- BENCHMARK TESTS - Intel Xeon Ice Lake: Added test data for these platforms. Current CSIT-2110 report data for Intel Xeon Ice Lake comes from an external source (Intel labs running CSIT code on “8360Y D Stepping” and “6338N” processors). - MLRsearch improvements: Added support for multiple packet throughput rates in a single search, each rate is associated with a distinct Packet Loss Ratio (PLR) criterion. Previously only Non Drop Rate (NDR) (PLR=0) and single Partial Drop Rate (PDR) (PLR<0.5%) were supported. Implemented number of optimizations improving rate discovery efficiency. - TREX performance tests: Added initial tests for testing latency between 2 ports on nic on the TRex. Added tests: IP4Base, IP4scale2m, IP6Base, IP6scale2m, L2bscale1mmaclrn. TEST FRAMEWORK - CSIT test environment version has been updated to ver. 8: Intel NIC 700/800 series firmware upgrade based on DPDK compatibility matrix. - CSIT in AWS environment: Added CSIT support for AWS c5n instances environment.
