Execution profile data shows how much time is consumed by functions, modules, and segments while the application is running. It can be displayed in the Sampling Analyzer as a histogram or as a cumulative histogram (if called-function times are included).
Execution profile data helps answer the following kinds of questions:
How much time does the application spend executing various functions, object modules, or segments?
What functions, modules, or segments are consuming the greatest amount of time?
If called-function times are included in the sample, how much time is spent by functions that call other functions?
