dpkg -S is slow, but not for that reason.  To do a -S, dpkg intializes the
ENTIRE internal database.  However, this is not needed.  It should just read
in each .list file, and if it matches the requested pattern, store it for, as
there might be more than one package that contains the match.  The act of
reading in status, and cross referencing all .list, is the slow part.

I plan on doing something about -S, but it isn't critical, as -S isn't one of
the main pipelines.
