There are stream parsers for JSON for Ruby too, including bindings for C libraries like YAJL - using the default JSON parser is an awful choice for doing comparisons like that given the massive overhead of the amount of objects it'll be creating for no good reason.

Agree, I believe the benchmark shown Yaji and jq in this repo is useful for you
