I have yet to see some of your code that proves that I am wrong. I wonder why?
Because, and this is just a hunch, I don't believe that you would accept anything that I showed you.
You seem to be stuck in this "optimization is always essential" mindset, which is usually the mark of an inexperienced programmer. Not trying to insult you, just stating the facts.
A few people have pointed out the caching problems inherent to skewing your example but you've done nothing to prove them wrong. Why not?
Profile twice, optimize once.
