Hi all, I am currently trying to compare TCP performance between the host TCP vs VPP TCP stack. Mainly I am focused on latency but am struggling to find tools to make the comparison. I have tried looking at iPerf as this has been used with VPP through VCL but this only provides UDP latency numbers.
Has anyone attempted to use Netperf using VCL? I have tried but it seg faults but maybe there are steps I can take to enable this? I have also looked at T-Rex although I haven't found a way to generate the test scenarios that I require. Stateful mode does provide tools for TCP testing and benchmarking but T-Rex emulates the TCP stack in this scenario. Any feedback here would be appreciated. Thanks, Anthony
