Reducing Memory Size

I started a new application tonight, and had a question.  When I run
my app with the ado components in it, but never touch them with code,
the app runs just under 4 megs of ram.

If I just run code to connect to access, query, and then set both
connections to nil, the exe takes about 8 megs.  In theory, since I
cleaned up both objects, should the mem go back down to ~4?

What are some things I can do to conserve memory with ado.  8 megs for
a form with 2 controls on it seems a bit of an overkill.  I get this
feeling I must be doing something wrong.
