How to profile ide code?

[Q139]

Is it possible to profile line executions or function executions without adding much additional profiling code?
Best if data shows cpu time not just times of lines or functions executed so it is easy to detect bottleneck code.
Have tryed valgrind already.

Hi,

Did you follow the Profiling Function Execution chapter of Qt Creator's documentation ?

[Q139]

I have gone over it few times but while using valgrind is it possile to output absolute % of function usages?

[SGaist]

What do you mean by "output absolute % of function usages" ?

[Q139]

@SGaist To output function usages compared to overall resource used by all other functions.

@Q139 Sorry, but your explanation is really unclear. Do you mean CPU usage (like 10% of CPU time)?

[Q139]

@jsulm Yes
