摘要
URL 是网络应用程序的基本要素。通过应用向量算法，我们构建了一个符合标准的快速 C++ 实现。我们的解析器比遵循 WHATWG 标准的同类解析器（如 Servo 的 rust-url）少用了三倍的指令，比流行的 curl 解析器少用了多达八倍的指令。Node.js 环境采用了我们的 C++ 库。在我们对现实数据的测试中，使用我们的解析器的最新 Node.js 版本（20.0）比使用传统 URL 解析器的上一版本快四到五倍。
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 the WHATWG 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.
