AMF3 is a new format and is more compact than AMF0. It doesn't duplicate custom class definitions or strings and has some other optimizations.
AMF0 is still good though and more efficient than any non-binary communications (ie AJAX XML or JSON). HTH, Sam ------------------------------------------- We're Hiring!

If interested contact [EMAIL PROTECTED] -----Original Message----- From: flexcoders@yahoogroups.com [mailto:[EMAIL PROTECTED] On Behalf Of Nate Pearson Sent: Tuesday, May 15, 2007 4:13 PM To: flexcoders@yahoogroups.com Subject: [flexcoders] WebOrb and the new Flex Article question (AMF0 vs AMF3) I've skimmed through the new Flex Article about remoting to .NET through webOrb. Sounds pretty cool and I'm looking to forward to trying it out. On the webOrb licensing page it says that the Standard (free) Edition of WebORB allows for Flash Remoting (AMF0) but not Flex Remoting (AMF3). What's the difference? Is one faster? Can I not use webOrb for free with flex? (I don't want to limit my self to 5 ips with the developer edition) I thought flex was flash, so it seems like AMF0 would work? Thanks
