I can't imagine there's any performance difference. The differences are down to personal preference, and accurate scoping. There's a pecking order if you don't scope a variable: 1. Arguments 2. Variables (local scope) 3. CGI 4. URL 5. Form 6. Cookie 7. Client <http://livedocs.macromedia.com/cfmxdocs/Developing_ColdFusion_MX_Applicatio ns_with_CFML/Variables7.jsp#1100240> This does mean that if you just say "#varName#", you'll invariably reference the right one, even if #URL.varName# exists as well. But maybe #Variables.varName# doesn't exist one time, but #URL.varName# does, and you don't notice the difference until one fateful day... That's the "worst-case scenario" argument for always scoping. The argument against, which often wins with me, is scope local vars all the time is a PITA!
