Re: Tracking cpu usage on application instances with JOnAS

You might try to use the new audit feature in JOnAS 5.2.0 M2 which 
provides a call tree for each request with detailed information such as 
the response time.
The tool helps the developer to identify the bottleneck in the 
application and the heavier methods.
