I think you have to merge embedded server directory structure and your
application directory structure and include current dir (".") in the
path. It should work.

That's expected thing. Firebird's remote protocol seems to be too
heavy for small data transfers, embedded engine driver accesses file
directly from Java, there's no socket overhead at all.

Type 2 driver, with the IPC URL (server and port is not present)
should give your similar performance, but it will allow shared access
to the database (embedded engine locks the database for exclusive
use). Try to download jaybird.dll from SourceForge.net, maybe I sent
you an old version of it.
