Thread bottleneck detection: User interface reference
Use these windows to locate thread bottlenecks in your application.
The windows are part of the Profiling and Logging perspective, which can
be used to analyze runtime problems.
The Thread View
The Thread View displays information for all
the threads of a selected profiling resource. You can control the format and
scope of the displays.
The Call Stack View
The Call Stack View displays stack frames
for all the threads of the selected profiling resources. The Call
Stack View is designed to be used with the Thread View and
the UML2 Object Interaction view.
