> you can expect to get better performance from the JIT than AOT
And you are likely to be disappointed. I think these claims have been made for the last 20 years, and Graal might be the first to deliver something general - all previous successes were very limited to small niches.
I like JITs and what they offer, but very consistently for me and almost everyone I know, in practice AOT works better (faster, consistent, no "heuristic changed in JIT version and now it's slow" surprises).
