Building a high performance JSON parser
Summary: At GopherCon Singapore 2023, Dave Cheney presented a case study on designing an efficient Go package for building a high-performance JSON parser. The project aimed to support streaming operations, be compatible with the encoding/json package, and offer an allocation-free or bounded API. The JSON parser's performance is determined by reading and parsing input, limiting function calls, and reducing data copying and allocations. The byteReader type was introduced for efficient reading, and the Scanner.Next function was optimized by manually inlining the Scanner.token function, improving throughput by 9-24%.
