I agree fully. Speed matters. Too many people consider CPU time too cheap to consider. I still marvel at how fast and efficient could Symbian OS be on a 190 MHz Nokia. (Though the API was hell.)

That said, it is also true that premature optimization is the root of all evil.

I suspect programming wisdom hides somewhere in between those two hills, neither of which is worth dying on.

Yeah, we should forget about small efficiencies, say about 97% of the time. Yet we should not pass up our opportunities in that critical 3%.
