I added a new method that only does a count(*).  It's still
not that much faster.  And since I really don't need fields
in my query (only getting a count), I am not retrieving any
fields from the DB.

I'm not loading _all_ of the data, just the data that I want
to work with for each instance.  Are you saying that I
should not be using container classes?  Just working
directly with the DB?
