This should be fine.. However, nfs is a slow as a dog and has major locking
issues..
This isn't really a problem as people only log in once..

However, you would probably see a performance boost and/or load reduction by
putting the session storage in some sort of SQL database. (I have a personal
preference for Postgres).
