Infrastructure for protobufs is pretty effective. It is parsed in browser, but several implementations show better performance than JSON decoding. A unified set

Infrastructure for protobufs is pretty effective. It is parsed in browser, but several implementations show better performance than JSON decoding. A unified set of libraries (or rather, code generators) to encode and decode in various languages is a plus, too. Both my current and last company used protobufs to encode API request data, as well as for things like config loading.
