To be honest, I found that in my use case (game dev, supported by bindings to a C library), PyPy was actually slower than CPython. I'd be curious to dig up my code and compare performance to a Nuitka-compiled executable.


out of curiosity, which bindings did you use?


libtcod. It was a roguelike.


Those Python bindings seem to use ctypes, which is indeed slower[1] on PyPy. They recommend[2] using cffi instead.
