There are a few good asumtions about why is faster, there are just speculations since I didn't profile jq or query-json.
The feature that I think penalizes a lot jq is "def functions", the capacity of define any function that can be available during run-time.
This creates a few layers, one of the difference is the interpreter and the linker, the responsible for getting all the builtin functions and compile them have them ready to use at runtime.
The other pain point is the architecture of the operations on top of jq, since it's a stack based. In query-json it's a piped recursive operations.
Aside from the code, the OCaml stack, menhir has been proved to be really fast when creating those kind of compilers.
I will dig more into performance and try to profile both tools in order to improve mine.
