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.
