You mention increasing the server's RAM; this might help if you're thrashing the server's dentry or pages caches.

Bumping up actimeo on the client could be a useful way to reduce the amount of GETATTR traffic. -- Greg Banks, P.Engineer, SGI Australian Software Group. the brightly coloured sporks of revolution.
