Today I decided to root my device. I haven't flashed any ROM yet. I was poking around with Voltage Control and found something interesting. There are couple of CPU Governers and it's defaulted to "On Demand" But the I/O Schedulers is just "noop" which always prefer in custom kernel anyway

Anyone think changing the Governers would make any different in performance or battery life?
I don't know if it's me but I get better resukts with interactive.

I think I found a bug report on it here but there doesn't seem to be any fix or work around. Anyone else seeing this problem and figure out a way to fix it?
Thats a normal bug...nothing you can do about it right now other than flash a custom rom w/ franco kernel. This kernel seems to have helped folks alot with high cpu usage during deep idle.
There's an ongoing discussion here.
I have my cpu ranging from 918 to 384mhz on AOKP...I was wondering if there is any chart/program available that would allow me to see how much time is spent on those respective ranges
System tuner pro shows a little bar graph.

Using CPU spy here as well. Works great.
Better Battery Stats now has this feature as well...plus all the other good reports it provides. (I used to use CPU Spy too)
Anyone know what is going on? Im on tweaked rom and perseus kernel. Why is my phone topping off at 1000mhz even though I set the minimum at 1800mhz
Please help. Thanks

I had the same problem,I had to change the governor to interactive
Just thought I'd share my benchmark results on k toons kernel
Not overclocked
Lowered min voltages by 50 each step except 1512mhz I left at 1300
Lowered min processing to 186mhz

Even during a benchmark the phone chooses to stay on the core 1-4 which are the slow CPUs.
It's easy to change per cpu scheduler type and options with kernel tuning apps, but is the big.LITTLE flip threshold available within linux or is it unreachable in firmware?
