I don't think so. Creating/destroying those components is fast and low
resource consuming. Also, new FB versions connect quite fast.

BUT, you can always use a database connection pool, that should speed up
things (connecting to db), and you don't even need to code your own, you can
use IBConnectionBroker that comes with IBX.
