You seem fundamentally confused, for example with tools like Cython.

Many extension module implementations in Python are literally as fast as pure C (not just nearly as fast with minor extra CPython overhead, but literally as fast as pure C by deliberately bypassing CPython VM loop and data models).

Cython can be as fast as C for simple use cases.

Because you're writing regular Python for a production service though, and not artificially writing optimized examples, then you will occasionally have to pay extra costs.

Are you perhaps a bit too invested in your own narrative?
