Understanding Flex transport protocols

I've been doing some investigation of Adobe Flex remoting and messaging protocols. I've used the HttpService before and was somewhat underwhelmed by its performance. Recently, I've looked at BlazeDS and the AMF3 binary protocol. AMF3 seems much faster than transporting XML over HTTP. Well, James Ward has an excellent Flex application that quantitatively demonstrates this performance difference.

Very well done and quite informative.
