I don't agree!

For NFS mounts, parameters are:
- Solaris	: TCP	(r/w)size=32768	   a big write = 6s
- FreeBSD mount	: UDP	          8192                   6s
- FreeBSD amd   : TCP             8192                   12s!!!!

This third setting is very slow, even if is TCP.

My answer: using defaults parameters with amd:
	opts:=rsize=32768,wsize=32768,vers=3,proto=tcp
