How much does the length of the variable name affect the speed of the program?

Question

C++ / C#

Forgive me for repeating the question (there is already such a question in the toaster, but there the question is asked a little bit wrong and there are no answers), how much does the length of the variable name affect the speed of the program? Somewhere I read that the length of variable names does not affect the performance of the application at all.

Answer 1

Somewhere I read that the length of variable names does not affect the performance of the application at all.

And there is. The length of the names does not affect the performance of the program in any way. The fact is that all names are converted and optimized by the compiler.
