OK, I'd highly appreciate any input. Portability is not an issue for me. But I have the feeling that kevents doesn't really scale too well, and I agree with you that I'm probably abusing the mechanism...

In general kqueues do scale well, and that's part of the purpose of them. We use them to multiplex I/O over many thousands of sockets. I haven't pushed them terribly hard on Darwin (just enough to hit some bugs in older versions) but I have no reason to believe they shouldn't scale well there too, relative to Darwin's level of low level performance in general.

Cheers,

Ian

P.S. if you continue to use kqueue, make sure you open the files with O_EVTONLY, if you aren't already. _______________________________________________ Do not post admin requests to the list.
