The Call Tree view is a representation of all function calls in all threads. Each top-level node represents a top-level function which was executed by a certain thread. Each node corresponds to a function call and contains metrics gathered during profiling.
This view lets you:
Quickly get down to actual application activity.
Look through the execution path of the process or a function.
Find and examine critical paths.
For each function call, view the percentage relative to total running time of all threads.
