They may also have been led to this by years of experience, as I have. I don't write poor-performing code when I can just as easily and cleanly write efficient code, and I have a lot of experience doing optimizations -- yet a little effort with a profiler almost always turns up surprises in real applications. This is so common, in fact, that I'm greatly surprised on those rare occasions when the profiler has no surprises for me!
