I honestly can't expect it to be much of an improvement since the
number of files involved compared with the size of the files is
minimal.  However, if you're opening/closing the files often it might
cause you problems.  I think in the normal case where it does matter
you have pooled connections so the open/close happens rarely.

Of course, if I had a good synthetic workload to pound on my DB, I'd
run a test... Sean?
