Intel AVX-512 A Big Win For... JSON Parsing Performance

In addition to the many HPC workloads and other scientific computing tasks where Intel's AVX-512 performance on their latest processor proves very beneficial, it also turns out AVX-512 can provide significant benefit to a much more mundane web server task: JSON parsing. The simdjson project that is focused on "parsing gigabytes of JSON per second" this week issued simdjson 2.0 and is headlined by an Intel-led contribution of AVX-512 support. The JavaScript Object Notation (JSON) data interchange format is heavily used by practically all major websites/web-applications in some capacity and can be dealt with by pretty much all programming languages. JSON really need not any introduction. The past few years there has been simdjson as an open-source (Apache 2.0 licensed) project aimed at delivering the highest performance JSON parser that can parse "gigabytes of JSON per second" and claims of being 4 25x faster than alternatives.
