I have recently gotten a 45x on a shitty vibe coded Python project by using mypyc (2x), replacing datastructures with more CPU-friendly alternatives (15x) and using some smarter heuristics rather than just brute force on top of that (45x total).

And I never left Python, the slowest language around.

AI is only going to make the problem worse unless you know what to look for.
