Default simultaneous CXF client connections?

[Kessel, Christopher]

I'm reusing the same client across multiple threads. 

At startup I do something like this:
        factory = new JaxWsProxyFactoryBean();
        client = (MyClient) factory.create();

Then I can have lots of threads concurrently making calls on that one client:
        client.doMyThing();

I know the client is multithread safe, but I'm not sure how many internal 
threads the client will use for communication. How many simultaneous 
connections will CXF (or whatever underlying socket pool) maintain and how do I 
change that value?

This is with 2.2.10.

Thanks,
Chris
