Yes we have. We did it in LifeCoach which is live in production for a fortune 50 company and was the MAX award finalist last week at MAX. I think we have some pretty significant real-world experience and feedback. > as for gzipping it... you might want to read this... > I did. I can tell you our production level benchmarking doesnt line up with that. When you turn compression on in the app in production (server class hardware) the difference in performance is noticeable with the naked eye. Forget timing it to mili-seconds. Literally our phones rang within an hour asking what happened to the app. I'm guessing this was JRUN also which is a different server, and we use a different compressor rather then a J2EE servlet filter. So as with all benchmarks, your mileage may vary. http://weblogs.macromedia.com/mchotin/archives/2004/11/enabling_gzip_c.cfm > amf is http tunneled as base 64 encoded data... Which means when it tunnels you effectively *double* the size of the stream in bytes marshalled. Now you have no control over that since the packet filtering firewall is in control. As I said, I'm an old CORBA dork. We used to do this HTTP tunnel there too. > > I'm a huge advocate of web services... but not if i can use amf... amf is > easily 2 to 3 times faster. (with INCREDIBLY faster load times) I'm not anti-AMF. I'm not anti-binary protocols, and I am *not* an web services snob. Heck, its just CORBA with a bloated 7bit protocol. I do however want to point out a few things folks havent thought about when they make a blanket statement like "binary protocols" are advantagous. Its all about education and differing points of view ;) -- Dave Wolf Cynergy Systems, Inc.
