OK, poked around in the netperf sources a bit, and it seems the UDP_RR test is *not* affected by the -R flag, so the issue is most likely with some other source of blocking. You could try setting up irtt on both server and client and see if that fares better - Flent should automatically pick it up if it's installed on the client, and you just need to start it along with netserver on the server-side: https://github.com/heistp/irtt/ -- You are receiving this because you are subscribed to this thread.
