Are there a lot of files in the directories that you run the ls -l on?
(i.e. > 4096 files per directory).

How much memory does the Linux server have? I am seeing contention between
the file system cache and the memory profile of the nfsd processes for the
available ram. Its gotten to the point where I think 1gb of ram is kind of
a minimum for a heavily used Linux nfs server.
  
Can you do anything to reduce the memory usage on the Linux server such as
not running X, cutting out some of the unneeded daemons, etc?

Got FreeBSD? :-)

Good luck!
