Question

Anyone family with Cpython internal? I want to rewrite a function

from Python in C, because that function is really slow from being executed in Python.

Supposed a shared library compiled in C, has a extern function which’s a heavy CPU-bounded computing operation.
That function was called from Python with ctype exposed from shared library .
My question is how native function was executed by cpython internally.
It’s handled by interpreter?

This also happen in C#, Java or other VM-based language, if a native function call from them, can I get native performance benefits?

yes, it's very common, it's used to do IO or threads, or similar things, so the main thread (of interpreter) is not stopped for that
