You can control how the profiling tools display information using the Preferences dialog box. To open it, select Options>Preferences from any profiling view’s menu bar.
In both Class and Routine views, you can choose how functions and events that are called more than once are displayed. Select the Aggregate Calls check box if you want the view to display a single line for each called function or event that represents a sum of all the times it was called. If you do not select the check box, the view displays statistics for each call on a separate line.For example, if aggregation is enabled and a function calls another function five times, you see one entry with five hits; with no aggregation, you see five separate entries for the same function.Internally, the profiling tool controls aggregation by using the AggregateDuplicateRoutineCalls boolean argument to the OutgoingCallList and IncomingCallList functions on the ProfileRoutine object.
