Data Exchange Efficiency (AJAX, JSON, E4X, Flex Remoting/AMF)

Flash, RIA, Serverside, Flex Add comments

I just got sent a very interesting link to a Flex app from James Ward that runs tests on a variety of different data exchange formats. The tests include results for:

1. Server processing time
2. Data transmission time
3. Parsing time and...
4. Rendering time

Of course no real suprises that Flex/Flash Remoting performs the best in all cases (the Dojo example appears to transfer quicker, but it is actually only dealing with 500 rows instead of 5000 in the Flex tests, maybe because it is sadly let down by the incredibly long render time), "classic" AJAX performs fairly badly, with JSON and Dojo falling somewhere in between.

Anyway the execution of this app is really slick, well worth checking out...
