Subject Re: Improving out of the box performance

I think stressing the use of DBCP (with examples) in the documentation is a
great idea, but I don't think the dbcp library should be included in the
OpenJPA image since it isn't a required runtime dependency.  Most
application servers and some JDBC drivers provide their own connection
pooling so the dbcp library would be a extra baggage - albeit, carry-on size
:-) - for folks using OpenJPA in those environments/configurations.
