 Well, I am using r/w NFS over TCP (IPv4) for /home.  The server is
 FreeBSD/i386 RELENG_4 and the client is FreeBSD/sparc64 RELENG_5.
 I tried to copy an ISO image:

  hrs at sparc64 % mount -v | grep /home
  home-v4:/home on /home (nfs)
  hrs at sparc64 % cd /home/hrs
  hrs at sparc64 % ls -al 5.4-RELEASE-sparc64-disc2.iso
  -rw-rw-r--  1 hrs  hrs  666693632 May  9 09:06 5.4-RELEASE-sparc64-disc2.iso
  hrs at sparc64 % mkdir subdir
  hrs at sparc64 % cp 5.4-RELEASE-sparc64-disc2.iso subdir
  hrs at sparc64 % ls -al subdir/
  total 651248
  -rw-rw-r--  1 hrs  hrs  666693632 Jun 11 17:20 5.4-RELEASE-sparc64-disc2.iso
  hrs at sparc64 % 

 Just a report ;)
