I think my rationale applies to client side code too, just in a slightly different way. It is so easy to write performant browser UIs these days, and a lot of that is down to these same sorts of hardware improvements (as well as V8 improvements). Even bloated web app front ends will perform very well most of the time. You can take that to the extreme of course, but you really have to go out of your way to do it. I’ve built frontends before without giving any consideration at all to performance, and they’ve always performed perfectly well. Websites like cnn.com exist, so it is demonstrably possibly to do it badly, but you have to stray so far from the light accomplish something like that.
