Why doesn't the performance tool work with modules?

Hello everyone, I hope you are feeling well!

I used to believe ModuleScript’s performance was attributed to the first script who required it, many people even told me that it worked like that. Well, turns out the performance is not attributed at all to the script who required, and the issue is that there is no way to know the performance of a module unless you copy the code in a Script.


Like literally, that tool is useless to know the Performance of a module script. Do you guys know why it has this behavior?
