Most of GNOME apps link against 50+ libraries, however small they are, many of them are executed frequently. Also, while prelink process has been fairly expensive some years ago, it is much faster these days; if you haven't installed any rpms in the last day, most of the days the cron job will just quit, if you have installed some, for libraries/binaries that don't need reprelinking it will just do a quick stat and nothing else, and even a full prelink takes just a minute or two.
