Howdy, I guess I'm throwing down a gauntlet here... can you pick holes in the performance metrics found for this set of web applications? 8) <http://www.macromedia.com/desdev/mx/blueprint/articles/performance.html> It's one of the few cases I've seen which has actually measured the server bandwidth costs and time-of-usage costs for roughly comparable web applications. (These aren't perfectly comparable web applications, because the SWF-driven Pet Market adds photos and localizable external text to the application features, but despite that it still comes in at a lower overall cost.) Most of the advantages come from Pet Market completely separating the data from the presentation layer... it doesn't require the server generate and transfer a new display page after each user interaction, or to download complex text scripts for trivial client-side interactions. SWF is more fun, _and_ more efficient. HTML is still great for documents, but SWF offers quantifiable advantages for applications. Anyone interested in taking the contrary position...? ;-) ---- More info: Index of Pet Market articles: http://www.macromedia.com/desdev/mx/blueprint/ Discussion group for the application itself: http://webforums.macromedia.com/richintapps/ My overview of what the app does, and doesn't do: http://www.macromedia.com/desdev/jd_forum/jd010.html Discussion thread for Macromedia blueprints in general: <http://webforums.macromedia.com/macromediafeedback/messageview.cfm?catid=22 0&threadid=37487> [Apologies for the multi-list post, but I think folks need to see this new stuff.] tx, jd
