Is there a way to test performance of code and it functions for optimization purposes ?

Question

What I am thinking of is :

I am currently trying to code efficient pathfinding system, and as I am changing mathematical operations, trying out various loops and approaches - all I can measure are framedrop and small freezes. I wish to know how much each line of code is contributing to this freeze, so I could optimize it better. Instead I have to rely on subjective duration of freeze.

I remove one needless boolean condition - freeze is slightly smaller. Or is it ? Was it in my head ? Should I try to search in arrays instead of in dictionaries ? Freeze seems to be shorter on arrays.. or is it..? You know what I mean :)

Did anyone come up with a way to objectively test optimization of code ? Or better - of single lines of code ??

Profiler is included within Godot.

Start the scene, then at the very bottom of the editor select 'Debugger' tab, under which will be 'Profiler' tab. You'll see how much time functions takes.

Wow thanks, it is much more than I could imagine :)
I have been programming for some time, but it was all turn-based games before, never had to dig in into optimizing process() :)
