> Between pyodide, pyo3, rust-cpython, and rustpython, I think Pyo3 is the best way to drop in rust in a python project for a speed up, if that is your goal. Some of the demos show using python from rust, but to me the biggest feature is without a doubt compiling rust code to native python modules. I'm using it to speed up image manipulation backed by numpy arrays. > There’s a setuptools rust [0] extension package that can be used to hook the compilation of the rust into the wheel building or install from source. Maturin [1] seems to be regarded as the new and improved solution for this, but I found that it’s angled toward the using python from rust. > There’s also the rust numpy [2] package by the same org which is fantastic in that it lets you pass a numpy matrix to a native method written in rust and convert it to the rust equivalent d

ata structure, perform whatever transformation you want (in parallel using rayon [3]), and return the array. When building for release, I was seeing speed ups of 100x over numpy on the most matrix mathable function imaginable, and numpy is no joke. What sort of algorithm was that? Generally getting 100x speedup on vectorized code is highly unusual even using handcoded c++. So I suspect it was quite loop heavy? In those cases I have also seen very significant speed ups. I have been using pythran [1] for speeding up my python code. It generally achieves extremely good performance. I have blogged about it here [2] and recently a member used pythran to speed up some nbody benchmarks [3] which was used in an article to argue for using compiled languages. That said I find pyO3 quite exciting and have been contemplating to try it with some of my projects.
