I have new benchmarks. And the benchmarks are by no means comprehensive,
but looking at details, it makes it obvious where some deficiencies in
jsoncpp is (compared to rapidjson at least). And FWIW, cJSON and
nlohmann have the same weak point.

I would be hesitant to base any conclusions on the benchmark solely. It
tests a grand total of 3 files for performance and I suspect the "hard"
one is really there just to showcase rapidjson rather than be an actual
test case…

The conformance tests are of interest though (and I doubt the
comprehensiveness of the corpus there as well).

More at 1 :) .
