I understand you're desire to cut out any and all fat from performance. But, as mentioned hundreds of times on this list, whatever "overhead" might be associated with that IF statement in negligible because there are other areas that will have much more of an impact on your app's performance. Look at those things first before you start scrutinizing an IF statement! Second, do you really have to use application variables? I personally hate them because of the whole locking issue. I'd rather spend the quite minimal overhead of setting a few variables on each page request via an include in Application.cfm than have to deal with locking. I have an app where I set 25 variables on each page load (page settings, colors, datasources, etc.), and the overhead is virtually negligible. When I stress tested it under a load of 100 threads (which I know is arbitrary and varies from system to system), that template takes a maximum of 10 milliseconds to process. That's a penalty I'll gladly accept if I don't have to worry about the locking BS. Just my .02 though. You may have perfectly valid reasons for using application variables. I just hate them.
