There are some basic things that can give huge performance increases without even parallelization: I wrote a Unicode crate because I needed a different interface to getting grapheme clusters from a string than the existing crates offered. I wrote a character category crate as well because I thought I would need it for this purpose (I didn’t). I managed to get double the performance of the existing segmentation crate and 10–20x the performance of the existing Unicode category crate. https://crates.io/crates/finl_unicode https://crates.io/crates/finl_unicode
