I think that’s my point. I get that JIT can produce faster code, I get that java is good enough for most things. But if you’re already in the performance critical regime there are other things you have to do where just having JIT available isn’t some magic bullet.
A possible magic solution is to load a JIT state from a previous execution and have good manual-optimization features to be like PGO. This would give JITs best of both worlds with being able to get to a strong peak performance and also not requiring manual tuning
