After being burn waaay too many times with one of:
1) write only code (for the sake of “speed”
2) optimization of the wrong piece of code
I do think it is much better to prioritize readability; then measure where the code has to be sped up, and then do changes, but try HARD to first find a better algorithm, and if that does not work, and more processor, or equipment is not viable or still does not work, go for less readable code, which is microoptimized
