There’s an old saying in software development: The only thing worse than no optimization is premature optimization.
It can be a true statement (if a bit hyperbolic), but far too many people seem to think it means “don’t worry about performance until the end.”
You should pay attention to code optimization throughout development and take time to solve rough spots periodically. You just have to know that some optimization strategies can become tech dept by gumming up on-going development.
Not usually, but Chris Cornell hit me hard. I had no connection other than loving his music and everything he did for Seattle musicians in the late 80s and early 90s, but I still think about it.
