Results of the latest benchmark from <https://github.com/miloyip/nativejson-benchmark>.
See <https://github.com/nlohmann/json/issues/307> for discussion.
Original post at 2016-09-09 to <json@yahoogroups.com>:
> Hi,
>
> This benchmark evaluated conformance, parse/stringify speed/memory, and
> code size. It can also be viewed as a long list of open source C/C++ JSON
> libraries.
>
> You can run the benchmark on your own machine by checkout this project.
>
> https://github.com/miloyip/nativejson-benchmark
>
> You can also view some sample results here:
>
> https://rawgit.com/miloyip/nativejson-benchmark/master/sample/conformance.html
> https://rawgit.com/miloyip/nativejson-benchmark/master/sample/performance_Corei7-4980HQ@2.80GHz_mac64_clang7.0.html
>
> If you make a new library, you may use this for testing conformance and
> performance. Afterwards, please submit a pull request.
>
> Enjoy!
