If you think about how a parser works it has to check each and every
character to see if it has discovered data ...

XML a verbose format? Well, isn't that what they have dual-core processors in laptops for ;-)

More seriously, XML seems relevant to the discussion because Flex "consumes" it, and it would be fairly easy to serve XML from RPG applications. Would a beautiful UI be worth the few extra milliseconds it might take for FLEX to parse it?

Verbose XML is more of a problem for bandwidth constraints than CPU constraints. But it seems that the bandwidth problem could be solved via HTTP compression. Take this 10K stream and knock it down to 4K.

I think XML formatting has become something of a scapegoat. The real inefficiencies are in distributed JEE, & .Net server architecture. But it's too hard to know where the bottlenecks occur, so they blame it on XML.
