Ripgrep is faster than {grep, ag, Git grep, ucg, pt, sift}

The article introduces ripgrep, a command line search tool written in Rust that combines the usability of The Silver Searcher with the raw performance of GNU grep. It presents 25 benchmarks comparing ripgrep against popular code search tools like grep, ag, Git grep, ucg, pt, and sift, claiming ripgrep stands above all in both performance and correctness with proper Unicode support. The author also provides detailed insights into why memory-mapped file searching is generally slower for multi-file searches.
