This also increases the interval, which makes the AQM less aggressive in general. Ok, thanks, I'll try. I didn't know what the implications of "lying" about RTT were. I do know that on a 60mbit ingress test I did to london = 10ms away, when I tried using metro = 10ms I killed single threaded throughput, so was wary of changing defaults after that.
