OT: automounted file timestamps

[kall mayo edu]

I have a filesystem I am exporting from our server and automount it on 
other machines.  There is a delay from anywhere from 1-45 seconds before
a modified/touched file on the server is updated on the system which 
automounts it.  How can I close this gap?

I export it with (rw,sync,no_wdelay) and automount it with -rw,sync.

E.g: I 'touch' a file on the server called 'it'.  I have a continuous 
script running on both the server and on the other machine that does a 
ls -l on the file.  The timestamp of the file changes immediately on the 
server machine.  On the other machine it updates the timestamp with a 
delay of up to 40 seconds, depending on how long it has been since I 
last touched it (i.e, if I wait a 3-5 minutes there is always a delay, 
if I wait a minute in between 'touches' then the timestamp on the other 
system updates almost immediately).  Is there some way to tune this?
