It looks as if it stabilized a while ago, and I see more fluctuations in between hours of the day, than I see between days. > > 17M*B*ps is 140M*b*ps and you already have a good relay :) > This is around the speed expected for standard CPU (150 to 300Mbps > per Tor > instance, best CPU available can "only" drain around 500Mbps). For a relay, yes. However, on an Exit node, the traffic patterns are quite different than a pure relay, that's why I'm asking here for that. Exit traffic uses a metric ton more, short-lived connections to different parts of the world, and there's a lot of things there that I could probably tune better.

That's why I quoted CPU usage, and the cpu usage per cpu isn't quite getting there for me. :-( > > You have to start another Tor instance to use a little more your CPU > (1 other > core) and so to drain additionnal 150-300Mbps. Scaling up on more hardware is always an option, but I really want to push the limit of the exit node, as the others won't be exits (Local network design, really) , and exit traffic is always more interesting. //D.S.
