If you have to choose between more than a couple of items use CFSWITCH, whi ch is a pretty straightforward case evaluation tool that speeds up processi ng quite a bit over blocks of CFIF/CFELSE/CFELSEIF statements.
If you use CFIFs, Look into using Compare() and CompareNoCase() in tests fo r equivalency. They're much faster, but a bit harder to grasp than the sta ndard ''cfif this eq that'' syntax. CFSET variables.blah="Y" CFIF NOT CompareNoCase(variables.blah,"Y") ...variables.blah is ''Y''... CFELSE ...variables.blah is not ''Y'' /CFIF http://www.fusionauthority.com/alert/index.cfm?alertid=5#Tech2 --------------------------------------- Matt Robertson [EMAIL PROTECTED] MSB Designs, Inc., www.mysecretbase.com --------------------------------------- ---------- Original Message ---------------------------------- from: Tony Schreiber <[EMAIL PROTECTED]> Reply-To: [EMAIL PROTECTED] date: Mon, 4 Mar 2002 17:16:24 -0500 (EST) I'm not sure, but talk around this list has said that iif() is SLOWER than cfif... > Not alot of performance issues, but you could consider using iif() > instead of a bunch of <cfif> > > > > > Doug Brown > ----- Original Message ----- > From: "Gilbert Midonnet" <[EMAIL PROTECTED]> > To: "CF-Talk" <[EMAIL PROTECTED]> > Sent: Monday, March 04, 2002 1:41 PM > Subject: site performance questions > > > > I'm redesigning a site and I have questions regarding how the use of > > <cfapplication> and <cfinclude> affects performance. > > > > 1.
