In my experience, I've gotten better performance out of FreeBSD on single or multi-CPU systems than I have out of Linux or Windows (or really any other system). Are these complains I hear of outdated, am I hallucinationg, or is there another answer? Although this is probably a better question for -current, what is the state of the scheduler(s), and what would be some good reading on the subject (specifically to BSD, and not just schedulers in general)? Thanks, -Jim Stapleton
