All you youngsters who never ran an app on a CPU at less than GHz speeds, you ought to be forced to write code for an early-80's PC. Now that was _real_ programming!
Also simply isn't reality anymore. Period. No matter how nostalgic you wish to be, all that matters are the circumstances of today. Since this is cocoa-dev, I'm sure you write Objective-C these days, which is a language wrought with function calls over the place courtesy of the runtime. But, that's not a bad thing. We're not dying in function call hell and more importantly, new programs are developed and brought to users with remarkable speed. A wise man once said, the slowest program is the one that hasn't shipped yet.
The moral of the story is that instincts on what is the best strategy for performance are great, and shouldn't be ignored, but the only things that really matter for performance are real numbers and user experience. Only way to determine those things is to first build a working version of your application. Can't do that if you're still in the office arguing about what's the fastest way to write something that will be done in a matter of microseconds.
