With FB 1.5 RC3, it's shorter than that. It's almost instantaneous.
The bottleneck is in Firebird's protocol, it talks too much between
the client and the server when preparing the DML/DDL statements. A
revision of the protocol is planned for FB 2.0, to figure out how the
protocol can be improved.

I would suggest timestamping the code after the prepare phase, to
compare the time it takes to retrieve the data.
