CPU governor and I/O Scheduler questions!

HI everyone. i have yet another question! lol.
i tried looking on google but noting specific for the epic. i was curious what the best cpu governor and the i/o scheduler is.
for the schedulers i have noop, cfq, bfq, deadline and sio
for cpu governors i have interactive, interactive x, ondemand, smartass, smartass v2 userspace, performance, conservative and powersave.

I use SmartassV2 and noop. SmartassV2, in my opinion, keeps the CPU frequencies low unless the power is really needed. Ondemand works well, but it is a little to generous some times. I use noop because it works well with flash memory. I am going to try out deadline because it seems like it would allow apps to load faster.

Just a quick FYI...
The SIO scheduler is supposed to be based on noop and deadline.
I haven't done much testing with it, but it specifically says it's designed for flash devices.

I was doing some testing with Quadrant and SIO gets the highest score. I am going to try it out this week and see how it is in the long run. Thanks for the heads up nube.

thank you. i noticed that sio was getting the best quadrant scores too.

Thank you for the amazing rom! one of the best for the epic right now.

I don't do roms...
Some roms might be using my kernel though, so I understand the confusion.

SIO seems faster but drains the heck out of my battery??
Im using VC deadline and ondemand and Im still at 100% 3 hrs unplugged with some minor messing around....ran the stopwatch for a bit trying to figure out what the hell was buzzing every (as it turns out) 1min. and have been messing around with the ui.
Nothing maujor but a few weeks ago I would have been at 90% by now easy

using smartassv2
with deadline quadrant score 2739
with sio 2733
both are good but as sio is lite version of deadline with a mix of noop so its balanced
deadline can cause some troubles if a program got stuck but its a performer
im using samsung galaxy sl i9003(ti omap3630 at 1.1ghz)

So far I am really loving SIO and smartassV2. My phone is fast when I need it to be and great on battery. From my rough calculations, I drain about 4% an hour when the phone is idle and about 7-10% an hour when I am browsing or watching a video. By the end of an average day, my battery lasts about 14-18 hours.

Help Please. What are the best Governers and I/O Schedulers....

I need not only performance, but battery life as well..
i currently have my clock at 998 high and 245 low
Performance governor and cfq i/o scheduler
but i want something that wont give me ANY lag, and give me good battery life

Depends on the kernel you use but currently I'm using MikG rom with the Underworld kernel, Smartassv2 governor, and SIO i/o scheduler. That's the best set up for ME. Just change things around and see what works out best for you and the set up you have. InteractiveX and Ondemand are also good Governors and Noop and deadline are good i/o schedulers as well.

The Performance governor that you are using now will drain the battery very fast because it will keep the cpu at the 998 most of the time or whatever you Change your max to

This should help a bit.

Which Governor and I/O Scheduler you use?

What you think gives U best battery or performance? I am in cake kernel v.09 so in mine I have noticed I/O scheduler becomes deadline even if I select sio normally.
Which governor U like the most? smartassV2, interactiveX or performance? (I dont know why I am getting biased to Performance Day by day).
And whats the highest and lowest frequency U use? (I use 600-820MHz:silly

A couple of questions.....

1st,
What is the best cpu speed for great performance and excellent battery life???
2nd,
What is the Best Governor for battery life and performance???
3rd,
What is the best IO Scheduler for battery life and performance?
I know there are a lot of threads with these questions, but they didnt have the best answers.
Im currently on 356mhz min and 1.3ghz max with governor performance and IO scheduler sio.

Hahaha.. Every Q u've asked depends on the phone. But i think this is the setup for every1 & infact almost every rom had this setup by default.
Governor: smartassV2, ondemand
I/o : sio, deadline
Freq : min-200Ghz, max-1200Ghz
Kernel is up to u. But fyi, its not all up to the kernel. The rom hav thier own role to achieve whats best. Again, everything's depends on the phone.

I prefer the governor badass. Performance locks it in its highest clock speed, so it´ll go through your battery really fast. As for the overclock, I have it at 1600 when gaming and 1200 when not gaming (SetCPU).

ok.

bcm21533 governor vs other governors

I have been searching for some time and i am yet to find any details on bcm21533 governoe for galaxy y.
In my experience it gives performance nearly as much as smartassv2 and gives battery life same or better than ondemand. i find it faster than interactive.
Yet i have never heard of anyone use this governor. anyone know why? isnt it far better than smartassv2 on our phone?
Have tried this governor ornhells fusion and percy kernel.

Indeed it works as this :
Only switching between max and min processor values (832 and 156 for example) depending on needed work, but maybe you are using some heavy app and speed = min it will be laggy , and light app on max freq will be battery drain, so interactive is better for me

I use kuro kernel with
Gov Ondeman
i/o noop
stable for me

I always used conservative and sio, never complained about this
