Sounds like an NFS config problem.  Please do some more testing...  use 
	time wget -c http://server/foo
to download a large file via HTTP and time it

Then do a similar thing via smb if you can - mount a samba share and
	time cp /samba/file ~
Samba should be the slowest due to overheads.  If NFS comes out slower
than smb then its a NFS config problem, and I'd suggest swapping from
nfs-user-server to nfs-kernel-server or the other way around :-)

For me, NFS is significantly faster.
