Hi Anthony, Sounds great! Let me know what you find. As for wrk, maybe give it a try. Typically, we’ve focused ldp testing on server side, e.g., nginx/envoy, since that was what folks were interested in. We should probably take a closer look at client side as well. Regards, Florin > On

Hi Florin, Thank you for the reply. I have seen with Netperf that actually there is TCP traffic going back and forth, a connection is established and then the client side crashes. I'll try to dig deeper to see what might be causing that. All I see on the server side is a received invalid

2022-08-17 Thread Anthony Fee
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
