as you point, FTP and NFS are two really different beasts; but also remember 
that NFS have a lot of configurable options.  sometimes one setting could 
improve performace in a given situation and degrade it on others.

at least, try changing these:

- TCP vs UDP transport.
- higher rsize and wsize (default 1024, some recommend 8192)
- lower rsize/wsize (sometimes just below MTU is better)
