VM warmup isn't consistently a thing, in fact for over a decade there has been plenty of observation of the reverse, that runtime optimization often slows performance. Systems languages (c/c++/rust) consistently outperform warmed up managed languages. And that is ok, it doesn't mean we shouldn't have managed languages, but they are slower.

Managed languages also exist in AOT with PGO data.
