The library aims at making anything related to JSON straightforward to implement. For some applications, this is a good compromise. The comment in the README is like the answer to a FAQ "How fast is it?"
You're making the false assumption that there is a compromise to be made - but there isn't. A modern JSON library should be the fastest (or about the same speed as the fastest), and vice-versa.
