Info 2 [Q]Getting the Best of our phone

Hey guys,
I'm Caine. I'm currently started using [ROM][KK][4.4.2][KOT49H] CyanogenMod 11.0 (20140122-UNOFFICIAL) and Hurtsky's ][CM11] HurtSky's Kernel RebornV3 with bigmem kernel.
And now, I started to wonder; With which configurations we can get the best performance overall from our phones? Which Kernel and IO schedulers, Memory management settings, etc.
With still keeping a decent battery life, how can we get our Ancora stand out?
Thanks for your answer at once.
