IRIX doesn't have the best NFS implementation in the world, at least
not when we were using it a year or two ago (IRIX 6.2ish).
Solaris is the benchmark NFS implementation that most people test
their stuff on.
For FreeBSD, the problem with NFS stems from a crappy initial
implementation. Fixing it is not easy, though we are making progress.
Rewriting it is out of the question... nobody has that kind of time
and it would be several man-months worth of work.
