NFS latency

            I'm currently running on the following version of linux.
 
             
Red Hat Enterprise Linux AS release 3 (Taroon Update 7)
(Linux release 2.4.21-40.EL #1
 
       I have a directory NFS mounted onto my linux box and I'm fighting latency issues.  My application needs to read from the directory as close to real-time as possible, but I've seen delays as much as 30 seconds.  Does anyone know of a work-around or setting to resolve this latency issue?  Thanks.

You don't really tell us how your application is checking the directory.
Is it polling using opendir()/readdir()/closedir(), is it using stat(),
or is it something else altogether?
