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.
