Hmm, I had always just figured that cfif and iif just compiled down to the exact same java anyway...
I wonder if one could have an advantage over the other if the condition was either true or false.... all this worrying over a few microseconds :) ~Brad -----Original Message----- From: Russ [mailto:[EMAIL PROTECTED] Sent: Sunday, July 23, 2006 12:30 AM To: CF-Talk Subject: RE: iif: am I understanding correctly? I wrote some test code, and it seems that cfif and iif perform similarly, and sometimes cfif ends up being slower? Is my test code flawed in some way? <cfset startTime=GetTickCount()> <cfloop from=1 to=100000 index=x> <cfoutput>#iif(isDefined("blah"),DE("."),DE(","))#</cfoutput> </cfloop> <cfset midTime=GetTickCount()> <cfloop from=1 to=100000 index=x> <cfoutput> <cfif isDefined("blah")> . <cfelse> , </cfif> </cfoutput> </cfloop> <cfset endTime=getTickCount()> <cfoutput><br>The time to do with IIF is #midtime-starttime#</cfoutput> <cfoutput><br>Time to do with cfif #endTime-midTime#</cfoutput> Russ > -----Original Message----- > From: Munson, Jacob [mailto:[EMAIL PROTECTED] > Sent: Friday, July 21, 2006 6:34 PM > To: CF-Talk > Subject: RE: iif: am I understanding correctly? > > > This part of the app is not going to take heavy traffic, so > > the performance > > hit would be negligible.
