For many years I was using UDP but while switching to Woody I have
encountered heavy performance problems under NFS v3.  Then I was
switching to tcp and since then ALL is working perfectly.

My internal FileServer has 48 User and /home is exported to 17
workstations.

But now while switching to Etch, I have kicked of the client side of
NFS while connecting to my Courier-Imap server on the same machine...
Exactly while mutt is receiving of the directory listing...

However, I recommend on the client machines to use:

    rw,bg,hard,intr,tcp,vers=3,rsize=8192,wsize=8192
