I need to write a text for programmers around the central idea that "performance is not best addressed at the code level".
This is a somewhat polemic issue, and I'd like to make my point as clearly and authoritatively as possible. I dislike the phrasing above because I feel there must be a more direct and natural way to say it, perhaps without the explicit negation "not best addressed".
Is there a better way of saying it?
Thanks,
