Here is a json parser/serializer that I've been working on for about a year or so now. There is benchmarks available at https://github.com/RealTimeChris/Json-Performance comparing it to the other 2 most performant C++ parsers/serializers. Let me know what you think! Cheers!
Congrats. Will check it out. What is special about your parser? Any high level design/architecture decisions that you can share? From your graphs, it seems to perform much better than simdjson which seems to be SOA in C++ land.
