I ran the benchmark of serialization, but the result seemed wield, I'd like to know why.
Command: ./run ser --libs jackson,dsljson,dsljson_reflection --apis databind CPU: Intel(R) Xeon(R) Gold 5120 CPU @ 2.20GHz JMH info:

The result:

However the result in README shows:

I'm wondering why the performance of dsljson_reflection doesn't match? Thanks all.
I'd guess because one uses reflection and the other doesn't
Thanks for reply, but see the score, in README, reflection is still better than jackson. However, my bench shows reflection is way to slower than jackson.
