IDK, "longest part of code" to me clearly seems to refer to length of the code (i.e. lines of code), not to length of its execution time; so I'd say that there definitely seems to be some confusion caused by the choice of words.

Just to further these two posts, that is why I asked my question at the top here. "Hottest" code, I thought, was already well established for most executed. I had never seen "longest" for anything.

To that end, I was taking it to mean that longest "synchronous" path through your system. Not necessarily a single method, by any measure. But, systems have plenty of what I will call "checkpoints" where code can be restarted/rerun with no hard to recover penalty. That is what I took to mean by longest.
