First of all, this sounds like an amazing project. My workplace runs isort+flake8 in pre-commit hooks, so making these even 10x faster would be a huge quality of life improvement for us.
Personally I'm interested to hear from you what are the specific reasons you can't achieve this kind of performance with CPython.
Usually the major factors are: A) python's generalised data structures (int, list, etc); B) extra overhead of common operations like reading a variable value, calling a function or iterating over a collection; C) no real multithreading (i.e. the GIL); D) lack of control over memory management.
I'd love to know if there's anything else that makes Python that much slower.
