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.
cool, that's good to hear. I guess I didn't mean that kqueues don't
scale well (in fact they do, it seems), but I'm just not sure how
good it is to crank up the number of open files to really large
numbers. However, I've now used setrlimit() to set it up to 5000, and
my machine is still alive, and the code works just great now. Guess I
can live with a limit in that region.
P.S. if you continue to use kqueue, make sure you open the files
with O_EVTONLY, if you aren't already.
