Performance Profiling Results

Performance Profiling for C, C++ and Java

The Performance Profiling report provides function profiling data for your program and its components so that you can see exactly where your program spends most of its time.

This section of the report provides a high level view of the largest time consumers detected by Performance Profiling in your application.

Performance Summary

This section of the report indicates, for each instrumented function, procedure or method (collectively referred to as functions), the following data:

Note that since each of the descendants may have been called by other functions, it is not enough to simply add the descendants' F+D to the caller function's F. In fact, it is possible for the descendants' F+D to be larger than the calling function's F+D. The following example demonstrates three functions a, b and c, where both a and b each call c once:

 

function

F

F+D

a

5

15

b

5

15

c

20

20

 

The F+D value of a is less than the F+D of c. This is because the F+D of a (15) equals the F of a (5) plus one half the F+D of c (20/2=10).

Note: The Min and Max values are optional, because their calculation uses a large amount of memory. To calculate these values, you must first activate the option in the Configuration Settings for the corresponding node.
