mir-ion and Asdf JSON libraries have been added to the 
Kostya/benchmarks.

https://github.com/kostya/benchmarks#json

If we exclude parsers with inaccurate number parsing then the top 
will be

1. C++, simdjson
2. Rust, Serde
3. Dlang, Mir Amazon's Ion DOM
4. Dlang, Mir Asdf DOM
5. C++ RapidJSON (Precise)

Mir Ion has been inspired by simdjson and Amazon's Ion binary 
format, which is used as DOM. Thus the mir-ion DOM for the 112 
MiB file costs 16 MiB comparing with 176 MiB DOM in simdjson.

Kind regards,
Ilya

Great work! What makes simdjson faster?

 Great work! What makes simdjson faster?

simdjson works with padded single memory chunk and use simple 
(but large) DOM format. Mir uses buffered input by chunks of 4KB 
and compresses data to the Ion format on the fly. Ion requires 
significantly less space but it is more CPU time expensive.
