Here’s another perspective on this: someday, you’re going to find bugs that require more code to work correctly, and more code is slower. If you’ve fixated on performance you now have a conflict of interest, and conflicts make it easier to talk yourself into bad solutions.

I say this as someone who has gotten a lot of pushback in my career about performance work. Performance is a thing that needs to be priority. It doesn’t trump all else.

Make it work, make it right, make it fast. When people skip step 2 (and a godawful number of people do) they make enemies of themselves to their coworkers.
