I released the Fast JSON library a few days ago.
This project is a fork of the JSON library by Florian F. (
http://json.rubyforge.org) with optimizations of the JSON rendering
- Implementation in C
It is used in a couple of production sites with as much as 10x-20x
performance improvement in the JSON rendering and no major issues.
Migration from the JSON to the Fast JSON library is as easy as changing
So far it works on Linux and possibly on OSX. It does not work on
as I am having a difficult time compiling it for Windows.
Full UTF-8 support is also not yet available.
