[ome-devel] bootstrap overhead?

[Harry Hochheiser]

Mike:

Creation of a new Factory involves going through the database  
delegate to connect to the database. I don't know what the overhead  
of a database connection is per se, but since it probably requires a  
network round-trip, I'd probably avoid this if I could.

What's the context? If you're working with anything under OME::Web,  
the Session always keeps the Factory and the Configuration around for  
easy access.
