Cyanogenmod ROM is one of the first few ROMs which I played with when I first started to root my first android phone Nexus S. There are tons of tweaks you can play with on this ROM functionally. I don't remember there's any good guide on changing the settings thus I have to give a try on each setting to see the differences. However today I came across a good guide to share here.
As of current, I am using paranoid android ROM, maybe I should give CM a try again.
