To me, that sounds like you are saying simple code is often efficient (or that efficient code can by simple), not that efficient code is simpler (which is how I interpret the original text).

To be very clear, I don't doubt the author (you?) had a good point to make, just that it was unclear what that was from the way it was presented, and to such a degree that it took me out of the flow of reading the post, and perhaps a less ambiguous way of expressing that concept (or omitting it, if it's expressed succinctly elsewhere) would be clearer and more effective.
