Python, PHP and JavaScript have significantly better performance for cpu-bound programs.

E.g. https://benchmarksgame-team.pages.debian.net/benchmarksgame/...

And I have measured ser/de for PHP, Ruby (and Rust, we needed to know how much faster JSON serde in rust would be, and compared it to Ruby and PHP). Php is probably much faster because the JSON ser/de is apparently written in C.
