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 filesI think this is the key takeaway. If you are parsing huge JSON documents, this will make a difference.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.
