If you only want to know what changed and not the details of the
changes, you can use the -s flag.  That avoids doing checkouts at all
(it just looks to see if the tags point to different revisions).  Even
if you do want the details, rdiff avoids checking out files where both
tags are attached to the same revision; if many files haven't changed,
that saves a lot of checkouts.
