I pretty much don't touch anything except I turn on prediction in the cpu governor settings, just for the small cores. OP says it's placebo effect, but I feel like the phone is snappier this way.Thanks!! Can you please tell me your settings.
Otherwise, I wouldn't touch anything except maybe the IO scheduler. I personally like deadline, but everyone says cfq is better.
Lol you probably shouldn't take my advice on kernels, most devs think I'm insane.
