I don't think it's true now, and I don't think it was true before. This strikes me as "old wives' tale" material. The IIf thing was (and presumably still is) true, because people typically don't actually write equivalent CFIF/CFSET stuff. IIf evaluates all of its arguments, which is an expensive thing to do. But, even if at any point it were true, coding for it specifically isn't necessarily a sensible strategy, since it may not be true in future versions of CF. And, even if that weren't an issue, the performance differences between these sorts of things would be negligible in any case. If you're worried about optimization, look at your database access and caching strategies. There's almost always room for significant improvement there.
