Slower by a tiny amount, and still faster than other C implementations. It's within the error box.

Also iirc there are improvements to those benchmarks in the pipeline, idk what happened to them (Veedrac and llogiq had something in mind).

Sure, you could hand-translate C in many cases (not regex), but that would be far from idiomatic. Most of the rust solutions try to still look Rust-y.

Regarding sse, if you care about performance and sse use a nightly compiler. That option exists. Rust nightly is still Rust.

You can also just bundle Rust w/ LLVM and have it JIT compile your application on start up which'll yield huge performance gains too.

But people may get salty about binary image size.
