This utility displays the results of a __profile.data file generated by a program that was compiled with the profiling options.
In its default display it will sort all functions by decreasing time and show the results. When you select the "modules" view, it will sort all modules that contributed to the executable and that were used by the profiling run in decreasing order. Within each module it will sort all functions that were executed in this module by decreasing order.
When you double click in a function display line, it will show the text of the function, together with the number of times the program executed each of the lines in the function.
