You could try adjusting /proc/sys/vm/dirty_ratio.
"Contains, as a percentage of total system memory, the number of pages
at which a process which is generating disk writes will itself start
writing out dirty data"
The default seems to be 20 on Fedora 13. For example to set it to 5%
(which is the lowest it will go I believe):
echo 5 > /proc/sys/vm/dirty_ratio
This should effectively lower the size of the buffer, but note this will
affect all file systems, not just NFS. However you may find that acceptable.
