"After Ilya’s talk ended, I started to think more about why performance always seems to be an afterthought with developers." In my (admittedly somewhat limited) agency experience, performance is rarely an afterthought to developers. Rather, it can be difficult to convince stakeholders that it's worth the extra time to ensure that each of these avenues is thoroughly explored. They'd rather spend their retainer implementing new feature X then making what they've already purchased perform faster. We do what we can in terms of adding additional time to estimates to account for these things, but it's always a balance. At the end of the day, someone still needs to pay for my time.
