> I came across a comment in google base libraries that said "This is faster because cache line is 32 bytes". You would want to ban that sort of comment? If you see a piece of code written oddly, then someone telling you why they wrote it that way is very helpful. If later you have to refactor it then it's doubly nice to know the reason it was written that way doesn't apply any more. I suspect your problem is with pre-mature optimisation rather than commenting, and if so I imagine the majority of programmers would share your views. But if that is the case banning comments that make it plain something may have been pre-maturely optimised doesn't seem like a good way of solving the problem.
