Yeah, one of the issues with the netperf UDP_RR test is that it uses more bandwidth the lower the latency, because it really measures "transactions per second" which Flent then converts to RTT. That is probably also the reason for the 'locking' behaviour... -Toke -- You are receiving this because you commented.
