Has anyone tested the stand alone driver with interbase 4?

I am looking for alternatives to interclient. I am getting terrible
performance with interclient/interserver. It takes about 700
milliseconds for a query to come back with results.

I downloaded and built the new driver, but I could not find any
documentation on the driver name (org.firebirdsql.jdbc.FBDriver???)
or the connection string. Can anyone point me to some info?

Thanks,
