I presume you are using the standard TQuery component set..
The size of the DB is nothing and I would argue first up that it has nothing
to do with any slowing behaviour whatever. The server manages the space -
don't worry about it at all.
You'd better tell us the FB version you are using. Also tell us if you've
fiddled the transaction isolation settings in the BDE. Tell us how you
generally manage your transactions.
