   $ time for x in `seq 1 1000`;do /bin/cp -f /etc/passwd ~/nfstest/file$x;done

   real    0m22.667s

Nearly same as your local disk. Though local for the above fs would 
be:

   real    0m6.299s

Are you running NFS over 802.11? That's a lot slower for me (above 
was switched LAN), but not quite as bad as yours:

   real    0m58.766s
