The Show Threads Tree option lets you show a graphical
            representation of the threads and calling functions within your application. You can
            drill down to see the detail of the lowest function calls. 
         
         
         
         To access this tree:
         
         
            - From the toolbar menu in the Execution Time view, click the Show Threads
                  Tree icon.
            
 
         
         
         
         
            
            
         
         
         
         
            
            The Show Threads Tree view.
            
            
          
         
         
         You can use this information to:
         
         
            - identify which threads are the most and least active
 
            - determine the appropriate size of your application's thread pool. (If there are idle
               threads, you might want to reduce the size of the pool.)
            
 
         
         
         
         To view quantitative profiling values:
         
         
            - In the annotated source editor, let the pointer hover over a colored bar. The CPU
               usage appears, and shows as percentage and time values.
