When I want some sw to go faster I do profile it, but I also give at least some thought to avoiding unnecessary copying of data or trig functions in tight loops. I regularly have run into people that say considering performance when selecting a data structure is premature optimization. It usually turns out they don't really want to test or profile and just want to churn through tickets. Anything that gets in the way of that bores them.
Measuring would attract even more protest because not only am I using my experience to choose (likely) more efficient algorithms, I am also spending yet more precious company time to measure its performance.
Fixed that for you.
