i remember reading that NFS needs tuning with ZFS even on solaris so you might want to look into that....i'm not an expert though. I CAN say this though. I have a machine with 12 drives and 8gb ram that i use for samba. FreeBSD 8.0 ZFS v13 It has only 10 or so clients but it has no problem maxing out 2 gigabit lines and it never freezes. It took some tuning for samba but it works great.
