Have you looked at the wait column (last one) in vmstat? How many files per server do you have? I've got over 2 million files in the pool. If your server is swapping, you _need_ more RAM. If it is not, more RAM will still serve as a disk cache, e.g. for filesystem structure and metadata and helps a lot to reduce I/O wait times.
