I apologize for doing this.  I hadn't realized that if I changed the 
subject line the thread would remain the same.

While I appreciate your comments about alternatives to NFS, I would like 
to know the answer to my question 'how fast have you seen NFS run'.  I 
personally have seen it at 100 MB/s over a gigabit ethernet line, but it 
was clearly network-speed limited.  I'd like to know if others have seen 
NFS running faster over a higher speed network.

The web page http://www.agami.com/products/ certainly suggests that there 
are products that can serve NFS at 500 - 1000 MB/sec.

Cheers,
 	Bruce
