We have a handful of FreeBSD NFS/Samba servers that are heavily used (mostly 
NFS).  I have not directly compared 4.x versus 5.x with any tools, but I can 
tell you that a UP P4 box with 5.x is fast enough to support 500 P4's (linux) 
over NFS, with some tweaking.  I've started making all my FreeBSD NFS servers 
5.x.  I'm doing some tests today with iozone+FreeBSD 5.3+RAID5/50/10+local/NFS, 
so if others are interested, I can post the information up somewhere when I am 
done.  Keep in mind it's for in house information only, so I won't be taking 
performance testing requests.. :)

Mike - let me know if you want any tweaks that I've done for anything specific.

I have seen the future and it is just like the present, only longer.
