With this tool , it seems that we can emulate multiple src IPs and use multiple cores to generate http traffic.

nnn , I can not find the root cause on this…
when I used one src IP ( remove –s option ) instead of multiple src IPs , I was able to run varnish-perf

Regarding socket error when specifying multiple Src IPs , I’ll look into the root cause when I have time.
