> Making string manipulation Heyyy another thing (and certainly I've done this myself) used incorrectly in such a way that it is extremely expensive. Specifically, concatenating log strings inside a large loop in some handler, and then not actually using those log strings because the production server didn't log down that low - but still incurring the cpu cost of the string concatenation.
