Michael Dick commented on OPENJPA-160:
--------------------------------------
We ran some more performance tests with the latest OpenJPA code and the issue
appears to be with creating an instance of the BrokerImpl (when Configurations
calls Class.newInstance).
I was surprised that creating a new instance turned out to take so much time
and I don't know what we'd could (or would want to) tinker with to try to make
it faster to create. I'm not thrilled about adding the complexity of a reuse
pool so I'm open to suggestions.
The pool that we used before was a two level pool thread.toString+user+pass ->
collection of brokers. Adding a non static field to AbstractBrokerFactory
sounds feasible too (unless there's an alternative to pooling).
Still looking into whether we need a key in BrokerImpl - I'll follow up on that
as well.
