I use numba a lot nowadays. Works perfectly well on all platforms (linux, windows, mac, even the M1) and gives speedups as expected (few percent for already well vectorized numpy code, and extra-large speedups for loopy code). I strongly recommend it for the performance critical part of your code. Many things are not supported yet, so it has to be used with care. I remember I needed a missing scipy special function and I the end I implemented it myself by vectorizing math.erf: it was surprisingly easy to do and a big success in terms of performance.
