Performance on Android

Is there any list of information about what is the minimum hardware requisites, to cocos2d-html5
runs, on mobiles the diference for device to device in matter of performance is so drastical,
any has any comments how should try to work on this.

PC Browsers works exelent 60-50 fps
ipad safari works good too.
Android firefox,chrome dramatic drops fps 1-4 fps on some low end devices mosly android 2.3, on the other hand works good on the galaxy note 2.

Thanks guys,

Android 4.0 supports the html5 features like canvas .,etc but android 2.3 and lower versions doesn’t fully support.

I have galaxy note 1 which has bad performance on the stock browser.
