And also false claims of "orders of magnitude", esp wrt Java https://deepu.tech/concurrency-in-modern-languages-final/

What's your ballpark guestimate?

aot language implementation based-on llvm, guess something like clang?

Then guess it depends which Python and Ruby language implementations, what exactly we need to do and how much we can call C libs :-)

In these benchmarks Java is not that far from Rust's performance. In fact, it hits #1 in some tests.
