He was asking for performance. And those technologies are mostly slow. Write an ecommerce site in assembly. It'll probably scream. But it'll take forever to write, and writing scalability features into it will be a major undertaking. Are you disagreeing with the fact that they are slow? Because, heck, they are. But that's the price that paid for quick(er) development time, scalability, reliability, and convenience. And that's not a bad thing. It sure is a good thing. > > > But, that's only half the story.

But some systems just will not scale, no matter how much hardware or code optimization or whatever what factors you have under your control you optimize. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~| Archives: http://www.houseoffusion.com/cf_lists/index.cfm?forumid=4 Subscription: http://www.houseoffusion.com/cf_lists/index.cfm?method=subscribe&forumid=4 FAQ: http://www.thenetprofits.co.uk/coldfusion/faq Signup for the Fusion Authority news alert and keep up with the latest news in ColdFusion and related topics. http://www.fusionauthority.com/signup.cfm Unsubscribe: http://www.houseoffusion.com/cf_lists/unsubscribe.cfm?user=89.70.4
