Feedback from user: I still have the same problem in Netbeans 5.5.1:  I am trying to optimize a web application that
runs in a number of worker threads and that makes calls to back-end servers such as data base or EJB servers.  The
following feature would help a lot:
     A Call Tree view that shows an aggregate over all the worker
     threads in my server.  This would give me a chance to find the
     methods that consume the most time by top-down opening the call tree.

As it is, this deficiency conspire to make it difficult to find the methods that actually take the most total time: the
Call Tree view is spread out over many threads that I must inspect individually to locate the worst method.

Apart from this, I found the profiler easy to work with (especially compared to Eclipse TPTP, which I have used before
and which insists on recording every single function call instead of an aggregate).
