What's the meaning of "hot codepath" (or "hot code path")? [closed]

I read this sentence (about computer programming):

As long as this is not in your hot codepath, the extra step should not cause issues.

What does it mean?


Solution 1:

This isn’t an English question, it’s a programming question. It’s also a duplicate of this question whose principal essential answer by Konrad Rudolph starts out this way:

Compiler hot paths are code execution paths in the compiler in which most of the execution time is spent, and which are potentially executed very often.
