In addition to rob ross's comments, we've seen even naiive usage of
pvfs can take advantage of having N caches avaliable when doing lots
of reads. (each io node has it's own VFS cache, it's own HDD cache,
granted, if you don't try very hard this effect goes away around 3 or
4 machines. oh, and "it depends on your aplication"
