yajl-ruby is not the fastest JSON library anymore, oj is. And it comes with MultiJson support and a #dump method.
Since rabl passes at least half the time converting a hash to JSON, I think it would be a great performance improvement for you to enable it by default and replace it in your guides.
I've started using it as well. I can make the changes one day unless someone beats me to it.
Updated the production guide to mention oj, happy to change it in any other guides.
Replace yajl with oj in docs and tests #365
Looks great to me. Closing issue. If @ccocchi wants to submit anything missing as a patch, go for it!
@databyte I wonder if we should just remove multi_json and depend on oj explicitly. Why would anyone not use oj? Is there any reason for us not to do that for 1.0?
Nope, that works for me! I have Issue #334 earmarked for that.
