Don't miss the 2023! The article really is already a little outdated: since Rust 1.78, the compiler uses some more aggressive loop unrolling (and a little bit of SIMD): https://godbolt.org/z/zhbobW7rr https://godbolt.org/z/zhbobW7rr OP wrote: "Looking at the assembly, it's doing some loop unrolling.", linking to https://godbolt.org/z/Kv77abW6c https://godbolt.org/z/Kv77abW6c, which is using "Rust Nightly", a moving target. By now, there's more loop unrolling. Loop unrolling started with Rust 1.59: https://godbolt.org/z/5PTnWrWf7 https://godbolt.org/z/5PTnWrWf7 Update: The code on Github shows they were using Rust version 1.67.0-nightly, 2022-11-27.
