Re: NFS performance question

 Perhaps you have a bad port on the switch? Try plugging the computer that 
you get 2 seconds into the other jack and vis a versa?  Have you looked at 
packets getting dropped? I may also be that you are flooding your server 
with packets and I believe NFSv3 is not tpc by default so it's basically 
best try. Are you running these with little else on the server? ~Ben
