Eh, correct, but you still pass unnecessary headers each time as part of the payload. It would even up the speed theoretically, but it's still a request reply model that demands a response, and you really don't need that for pub/sub for example.

TCP just feels cleaner as a protocol for this kind of stuff but I would certainly concede that speed of HTTP isn't as bad as people would make it out to be.

Also, I'm considering adding createFastSpeaker and createFastListener to the API for people like game makers who don't need to guarantee delivery of certain data over UDP.
