Which is better CTG or MQ?

I saw your response for CTG or MQ. I want to know which one would be better from performance (both CICS and mainframe...

performance and overall performance of the system) point of view.

If the application is let us say, EJB based, the call to CICS programs comes from a session bean (synchronous) and the bean (client) waits for the response from the CICS program to proceed further.

In this scenario which one would be more performing -- CTG or MQ based solution?


I don't really accept that performance is the issue here, it's UnitOfWork and associated considerations. However, in overall terms I expect it should cost less to use a CTG than MQ but don't forget the accounting is done in a lot of places so the calculation will be difficult.
