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 be data driven and optimize the hot data path, the other code paths optimize for simplicity (and the majority of a system is the latter)
