Achim,

A> Sorry for asking this on firebird-devel:

sorry for replying only in fb-support. :-)

A> Is there a way to _convert_ an existing database from dialect 1 to 3?
A> I have a database with ~180 Tables filled with 12.5 Gigabyte data.

Use gfix. Also, look at the IB migration guide.

A> Is dialect 3 database access faster over dialect 1?

I don't think so.
Ciao
