@ -67,6 +67,9 @@ Summarizing, `ripgrep` is fast because:
[Rust's regex engine](https://github.com/rust-lang-nursery/regex).
Rust's regex engine uses finite automata, SIMD and aggressive literal
optimizations to make searching very fast.
* Rust's regex library maintains performance with full Unicode support by
building UTF-8 decoding directly into its deterministic finite automaton
engine.
* It supports searching with either memory maps or by searching incrementally
with an intermediate buffer. The former is better for single files and the
latter is better for large directories. `ripgrep` chooses the best searching
