There seem to be a lot of people who think that questions regarding optimization of working code belong on Code Review, while others think such optimization questions belong here (on Stack Overflow, not meta, of course).
Now, I agree some optimization-related questions should be directed to Code Review (particularly ones with more code looking for more in-depth/complete review and optimization), but I personally don't think optimization questions should be automatically punted to Code Review (especially if they're smaller amounts of code and are looking for a targeted review/optimization).
It seems to me that Code Review and Stack Overflow have some kind of intersection of interests in relations to optimizing code. Is there a more authoritative source (as opposed to my own opinionated brain) which I (and others) can consult to help clarify the ongoing confusion of what belongs on CR and what belongs on SO (specifically regarding optimization of working code)?
I've seen the brief FAQ of CR and SO both quoted in favor of keeping/punting optimization-related questions. I'm looking for an additional resource/community consensus which I may use to further clarify this for myself (and then share said resource with other punt-trigger-happy users).
