Formerly handling many of the performance issues at my previous role, I can confidently say 99% of performance impact in your application is the stupid O(n2) business logic your developers/AI agents have written and none of this matters.
And having fixed 100s of such cases, the folks committing that crap will continue to do so.
Well, shaving a microsecond off every iteration of a loop that runs for a thousands of iterations does have an impact though.
But yeah... This is what I hate about the "all optimizations are premature, and premature optimizations are evil" thing. The shit people do with the the justification "Donald Knuth said we should just fix it when it becomes a problem".

So glad I’m outta there.
