PyPy's New JSON Parser
> In the last year or two I have worked on and off on making PyPy's JSON faster, particularly when parsing large JSON files<p>I think this is the key takeaway. If you are parsing huge JSON documents, this will make a difference.<p>Otherwise, it's super hard to beat Python3's native implementation. I've tried them all - hyperjson, orjson, ujson... none of them provide any significant gains on parse speed of smallish JSON documents, even if you are parsing thousands of small(ish) JSON documents in a row.
