Faster than CyanogenMod 7
Ice Cream Sandwich was designed by Google to operate faster than its predecessor Version 2.3, codenamed Gingerbread. (The Version 3.0 series, Honeycomb, was quickly put together for tablets, and not fully optimized for speed, and Google did not release its source code.) CM9 has a noticeable increase in performance compared to CyanogenMod 7, which was built upon Gingerbread. Animated effects, launching apps, and swiping through menus and screens happen smoothly and quickly. Even if you already have CM7 installed on your phone or tablet and are happy with it, you ought to try out CM9 if it’s available for your device to experience this improvement.
