Hmmm ... are you searching within the files or the file names for patterns?

Gluster does have some pretty good caching facilities, with the downside 
being that we seem to catch lots of bugs in this layer.  There are 
pre-fetch capabilities as well.

The issue is that this is going to be a *very* seeky load.  The 
underlying system IOP rate will be one of the bounding elements.
