Hi,
I wrote an article a few days ago on optimization for a cocos2d-x project.
You can read it here: http://www.frozax.com/blog/2012/05/optimizing-graphics-performance-ios-android-cocos2dx/
I hope it will be useful to some of you!

Awesome article.
I add a link to your blog at both [[Native]] and [[Performance]] wiki page.
