It’s a good start, but you can’t generally get even remotely close to hardware potential in Rust, let alone Python.
I had to implement a separate C99 library to always trigger the newest SIMD intrinsics, occasionally leveraging SVE on more recent ARM CPUs, that compilers don’t know how to generate.
That library is in turn used in USearch, which is designed for Approximate Search, but some users recently reported that they use it for brute force as well… where it performed 20x faster than FAISS.
