Feasibility of adding a json engine like yajl, oj with JSON Builder ?

[boddhisattva]

@dewski Can you please tell me if json_builder uses ActiveSupport JSON or Multi JSON. In case it uses Multi JSON, is there a feasibility for me to specify a JSON Engine for json_builder ? The idea that I am trying to incorporate in my app is to parse the JSON faster, this way I can take an additional step towards reducing the overall time json_builder takes to generate the json response.

If there is something possible on these lines, can you please tell me how to go about it ? Thanks.
