I'm trying to find a well-regarded JSON library benchmark, preferably cross-platform, preferably language independent. I'm most concerned about C++ performance on Linux, but would like to make comparisons and find something that works well on macOS and Windows too. Also, I'd like to benchmark implementations in C/C++ as well as other languages.
I've found a few benchmarks that are interesting, but they all seem to be Java only and the results aren't that impressive.
Is there a benchmark that can be considered definitive for comparing solutions?
BTW, this is not a duplicate. I'm looking for a CSV benchmark too...figured I should ask the question separately.
