On the faster machine the response time is outstanding, no problems there.
On the slower machine it probably was too slow for production work, and I do
think that most of that time was taken up in the DB connection.

Some things you might look into to enhacne performance might be Connection
Pooling and some SQL things like Prepared Statements and Callable
Statements.  I'm not doing either of these right now but I understand they
can help performance.
