It also has excessive system call latencies. There is a paper from Harvard or Berkeley (I think) that describes some of the issues, where they compared NetBSD and NT. For many applications, NetBSD and FreeBSD aren't different enough that the conclusions about the relative behavior of NetBSD and NT, would not be the same as FreeBSD and NT. > > Is there anything in the argument that this could be because Windows NT > Server is graphical (it uses the Win95 interface) whereas BSD isn't [need > not be]? > If you run Xwindows on a FreeBSD server, you'll notice only a small decrease in perf (unless you are memory limited.) > > Is it because of inefficient programming by Microsoft?

I wouldn't have done an OS like NT was done (from what I can see about it's architecture.) That isn't to say that my result would have been better though :-). -- John | Never try to teach a pig to sing, dyson@freebsd.org | it just makes you look stupid, jdyson@nc.com | and it irritates the pig.
