Is ondemand governor really unstable? - Vibrant Q&A, Help & Troubleshooting

In cm7 the default governor is ondemand but it used to be said that this was unstable so use conservative
I don't really tell a difference anyone?

[Q] What's the best CPU governor?

And what are the pros and cons of each? Thanks!
smartass is the best i suppose....it saves on your battery and increases your cpu freq. as and when required

Smartass and savagedzen do their job almost the same but savagedzen is better. Thats for me. Don't know for others.

[Q] I/O Scheduler - NOOP or SIO ?

[Q] I/O Scheduler - NOOP or SIO ? I know there has been speculation that this is a negligible difference in overall efficiency, but I have been on SIO and it seems less efficient than NOOP ? Is this something anyone else has experienced ?

NOOP is ideal for solid state devices, like SSD, RAM drives, phones, tablets. Not so good for traditional disk drives.
Having said that I wonder if the difference is noticeable without benchmarking..

What kernel are you using?
Subzero. It has like 10 options but I don't think that is one of them

Honestly, I doubt you'd notice a huge difference...unless you're very taxing on your phone, or already super familiar with how it runs lol
Which I am both. I use my phone at least 2 hours of solid screen on time a day and I have flashed somewhere in the neighborhood of 20 different ROMs. I like to experiment. I think sio and noop are very similar but I can't quite figure out which one is better

I prefer sio, it based on deadline

Yes because they are controling the cpu frequences

For perfomance Ondemand is pretty good...
SmartassV2 is good as battery efficient governor...
But I think the best way find is doing it in your own...
Read this thread. It is pretty informative....

CyanogenMod 10.1

Hello everyone. So basically i have a question. Is anyone facing lags on cm 10.1 new nightlies? O have a lot of time with this rom, and i must say that 10.0 was much more smoother (at least for me)
On 10.1 even the homepage is choppy... I'm running Pegasusq overclocked 1.7 GHz with deadline scheduler... any advice you would give me?
Best regards

I felt the latest PA ROM was quite laggy too...
Use Siyah kernel and I have a few tips for settings:
--Over clock to 1.5GHz
--use lulzactiveq
--turn gentle fair sleepers off
--set touch boost to 1000Mhz (or more if you want)
--turn android logger off
I also undervolt all frequencies by 75mv.... I do a lot of PC tweaking and you'd be surprised how much that little amount can reduce cpu temps.
Hope it helps. Did for me.

It isn't really noticeably different to stock settings tbh.. (I.e. still not a patch on Samsung). Give it a go and see how you get on. It definitely makes the ROM smoother.

That means better than a normal cm 10.1 (sigh)
I did the things you told me, except the undervolting, and gotta admit it's better... Thank you very much

I have read comments from several devs that claim that this makes no difference and that those saying it does are experiencing the placebo effect
Addition: in case you are experiencing scrolling lag in any apps, make sure you have force GPU rendering ticked in developer options!! Absolute necessity in any JellyBean ROM.

Though I can change the governors on a stock kernel. Which one do you recommend? It was ondemand at first, I changed it to Intelliactive but noticed the battery goes a little fast. And then changed it into convervative now. Let's see what happens.

Ondemand is best balance
Intelliactive is more active inteligently like the title says... Aka using more battery then ondemand
And i usualy forget about conservative becsuse its as bad as ondemand with battery

Why is it not possible to over clock stock kernel? Im sure it has been done with other phones so why not this one??
Sent from my D6503
If you overclock stock kernel, it's no longer stock. It's a custom kernel.
