@screwlisp wow, `(declaim (optimize speed))` really makes a difference! I'm seeing factor of 4 improvement...

@screwlisp Are bignums in SBCL allocated in cons space or in heap space, does anyone know?

Agreed. #CommonLisp on Android ( #cl_repl) is capable and plenty fast enough on a Pixel 8a running your factorial code. 😎
You can make CL faster than the C/C++ used by NumPy: https://stewart123579.github.io/blog/posts/code/calculating-a-dot-product/#python-vs-dot-r-vs-dot-lisp-timing

@alwayscurious @vashti define fast. I can compute the factorial of 1,000 in under one millisecond on an ordinary laptop in several different #Lisp dialects, without optimisation.
Is that not fast enough for you?
