There's MessagePack for substential improvement of parsing speed and size of JSON while still being straight-forward to parse and debug. These guys (Capt'n'Proto) are for cases when that's not enough either. As I understood, Capt'n'Proto removes the need of parsing itself, so you don't have to parse a data structure into your language's structure if you want to access a field, you just keep your data as a binary blob in memory without copying or parsing the whole thing.
