When I care about performance over most anything else, I take this guy's approach: https://www.youtube.com/watch?v=Kdwwvps4J9A https://www.youtube.com/watch?v=Kdwwvps4J9A It's not appropriate for every project, but if maximizing performance is your goal, you should be tracking performance constantly as you work, not as an afterthought late in the project. Late profiling leaves too much room for a thousand small inefficiencies to add up, and it adds too much time between making a decision and understanding its impact on performance.
