URLs are fundamental elements of web applications. By applying vector
algorithms, we built a fast standard-compliant C++ implementation. Our
parser uses three times fewer instructions than competing parsers
following WHATWG URL standard (e.g., Servo’s rust-url) and up to eight
times fewer instructions than the popular curl parser. The Node.js
environment adopted our C++ library. In our tests on realistic data, a
recent Node.js version (20.0) with our parser is four to five times
faster than the last version with the legacy URL parser.
