Hi! I have been trying to test VPP's potential for TCP/IP latency optimization. When I run socket_test.sh without any special parameters (so just comparison between native-kernel, native-vcl and native-preload) it seems that preload around six times worse than kernel. I have also tried this same test with few different hardware setups. I also tried to compare LD preload to kernel performance between cloud VM's without using the provided script and ended up getting similar results. All test are run on 18.07 (build-release).
What is the status of VCL and LD preload? Should it be working and do I miss something obvious maybe? Thanks, Ville Kapanen
