True. The msgpack serializer was probably used in a suboptimal way. The integer 3 can be encoded by msgpack in one byte as well. I never use doubles which is probably why I didn't think of this case. Integers are actually always <= bytes in msgpack than the JSON ascii representation. Anyway - benchmarking is hard.
