Hmmm... we have several hundred users.  We have a cache size of about
slightly less than 2Gig.  However, it's not yet been filled.  It hovers
around 500MB of the total 2Gig used.  We're getting about 25% cache hit
rate.  When we only had 75MB for the cache we were getting about 6% cache hit
rate.

Clearly, the size of the cache is a factor.  But additionally, so is the
breadth of interests of the user community.  If the user community interests
are varied enough, then each file is only loaded into the cache once, but its
never retrieved by someone else with the same interest.
