Ripgrep is faster than {grep, ag, Git grep, ucg, pt, sift}
Summary
The article benchmarks ripgrep against several competing code search tools across multiple scenarios, showing ripgrep's dominance in speed and Unicode handling. It explains architectural choices (Rust regex with UTF-8 integration, Teddy SIMD, and Aho-Corasick fallback) and discusses memory-mapped vs buffered I/O, .gitignore handling, and inner-literal optimizations that contribute to performance.
