Zip both resulting strings and I bet you it's a wash. Since JSON is mostly used (at least by me) for sending data to client side javascript, it doesn't make a difference. JSON is just easier.
Yup. We tested messagepack a while back in our environment. Speed difference was 2% versus gzipped JSON. Not enough to invest time in changing a working system and losing human readability.

Also - I'd have to assume that the performance benefit of native JSON parsing in modern browsers is non-negligible...
