yes, it sounds like the network.  changing nfs to something else wont 
fix that.

what bothers me is that even for a 10 mbit network, it sounds like you 
have a network problem.   at home, i stream music down on a 384k line, 
while my spouse does something similar (different stream) in the other 
room.  when I stream video down, my browser (& its plugins) has to stop 
and buffer it, but I am often getting only 10-20k throughput from the 
source.

I would suggest upgrading your network, but it sounds like you dont want 
to, so I wont. I think it would be cheaper or as cheap as buying a disk 
drive.  You  might just have a kinked cable somewhere.

yes, these are my opinions.
