I'd probably go a little further than this ... place the originals on 
gluster, and on apache/other startup, copy the files to a local 
(RAM)disk, and work from there.  You can even set up scripted push of 
originals with some simple scripting so that on (RAM)disk versions are 
kept in sync within some interval.
