That is indeed the case, but at the same time, even early Java (back when it was still a bytecode interpreter without JIT) was considerably faster than Python is today. Python is kinda slow by design - just look at the descriptor protocol for an example.

It has a lot of upfront costs, but that is separate from "hot" performance once everything is loaded.
