Sorry, I missed the link to https://github.com/sugawarayuuta/benchmark – I don't find its contents very easy to digest, and there's often more to an encoding library than benchmark perf - how does it compare in terms of functionality, correctness, etc would be great to cover too. The README just has vague discussion of "some other alternatives" which isn't very actionable.
> Those don’t make much sense to me nor do I see a comparison with the segment high performance json library.
There is a column named SegmentJSON in the benchmarks page [1]
https://github.com/sugawarayuuta/benchmark - Performance looks pretty comparable to go-json (https://github.com/goccy/go-json). Faster in some tests, slower in others. Not sure if it'd be worth switching for me. Good work either way. Would be interested to see benchmarks of the latest version.
