I don't say that you need to remove Adsense code, that is ridiculous to I say that... I'm saying that you don't need further optimization, because you have remove all thinks that you don't need to have in your page, and that have big size.
@RECEP I'm sorry, my English isn't so good. I'm saying that you page(s) now have optimal size ~160kb (total), so if that is my site I will stop further optimization...
