With 2k connections the overhead of select() is going to start to be a problem. You would notice the system time going up. -threaded may help with this, because it calls select() less often.

we should be using /dev/poll on systems that support it.

And kqueue for systems that support that. Much, much more efficient than select.

Yeah, yeah. We know. We just haven't got around to doing anything about it :-( It's actually quite fiddly to hook this up to Handles - see Einar's implementation in Network.Alt for instance. Cheers, Simon (who wished he hadn't mentioned select() again)
