----------------------------------

Hi Jaikiran,

I am working on a special user case, which include one deployment jar file with several working modules:
Including lots of Stateful Beans, Stateless Beans, and also MDBs, 
and those beans were separated into groups: such as manufacturing, supplying, and customer order, and each of those modules are under different workload, but they deployed in a single jar file. 
Through our continuous monitoring, we found that over 90% CPU cycles consumed in our system is the following method: org.jboss.threads.JBossThread.run()
I think this might be caused by synchronized waiting or lacking of thread to execute the specific task, and even I increase all my defined threads in the configuration, this issue is always occurring (I didn't look at the EAP6.1 sourcecode yet, but if needed I will do). 

Your comments is highly appreciated, I know this fix may cause some other serious issues, or please let me know if you have different thought to this problem.

Thanks and regards,
Weixing

> For performance of an application to be scalable I need to configure sometimes a thread pool to an EJB. The pool is not shared with other EJB in the deployed application.
>  For example 
> PoolA - EJB Dog
> PoolB - EJB Cat
>  To configure this the ability no define the thread pool name for an EJB. Rather than an EJB to the shared thread pool as it currently works.
