Are governor's and schedulers the samething.If not what are schedulers used for?and what are they?arn't governors pretty much built into all new kernels?are schedulers built into kernels as well?If someone could please explain I would appreciate it.

I decided to start a thread for governors used in your favorite kernels such as eugene373-kernel or ezekeel-kernel OR steve.garon-kernel OR mathkid95-kernel OR netarchy-kernel OR terryhau-kernel OR morfic-kernel ..... I may be missing a couple but I think these are the most used kernels for our Nexus S devices.
The reason for this poll is to help our devs include/exclude governors not being used at all or the least used! And also to establish what is the most used governor giving a hint to our devs to maybe start hacking them to make them even better.
Lulzactive v2. It gives me a nice control over how it works so I can tweak on my needs.

lulzactive V2
Thanks guys! I just added the options for voting your best governor, if you do not mind please VOTE and also add what IO-scheduler is used as well.
ondemand..
15000 sampling rate, 98 up threshold.
Lulzactive V2 with SIO Scheduler.
This is great!!! Tks for the votes! Let's help our devs with DATA and we help them help us!
BTW, I am using LULZACTIVEV2 - SIO combo as well!

I'd like to use lulzactive v2 but it has too many options to configure and I like it simple so I switched to smartass v2 + sio

This is my favorite configuration as well.
lulzactivev2 is up.... yep it has more options, therefore better to test for more battery savings!
I read good things about new governor eugene373 implemented in his kernel called *scary*.... might try this one later when done testing steve.garon's kernel and lulzactive gov.
Interactive is the best for me. I recall a kernel/rom dev stating that he uses solely interactive as well.
I've been on math kids kernels since 5.0 on ginger bread cfs and smart ass v2 btw. I've tried lag free but it makes my music player stutter when the screen is off. My phone likes speedy kernels too so I switch back and forth

Lulzactive V2 (I REALLY wish it had a better name!) with SIO. Works best with Matr1x, SG-NS-ICS and ICUP on my NS.
Edit: I think I got a little hasty answering this, Ondemand, by far the one I've used most, considering I used to run Oxygen on my Desire and Thalamus' kernels are phenomenal. So Ondemand for me too.
Ondemand for me.
Ondemand and lulzactivev2 winning the race!
I can confirm sio-lulzactive work nicely with Steve.Garon, eugene373, mathkid95. I had more success with Matr1x kernel with this combo my battery last me 30+ hours of heavy use!

Just did a fresh install of latest Peter Alfonso's ROM and speedy 5 kernel.... I'm testing the scary governor along with noop IO scheduler... so far so good!
Who knows the difference and can explain what the lagfree, interactive, ondemand and userspace CPU Governors are? Please, no guessing, I can do that too. If you know what some of these are, share the info, please. Thanks.
Google or read set CPU readme ....

Hey,
I decided to mirror your kernel:

Not that I can think of, don't have much time to be posting but all I can think of is the bootanimation.zip needs to be named /system/media/sanim.zip

Defaulted to SIO scheduler for me. Changed ala system tuner to NOOP. What is it undervolted by as the default?

Thanks for the new Kernel!
Just curious, but does it take a lot of work to add overclocking ability to kernels?

sio is better than noop
all I can say to this kernel.... is wow. I'm in love with the lionheart governor. Haven't got around to trying the rest but its sooo smoooth. Underclocked to 1.242 and its still running nice. I was also able to underclock and additional -50mV and running stable. Sorry faux, I've turned traitor

Why? I read about all of them, but can you explain? This is what i've found
SIO
Simple I/O scheduler aims to keep minimum overhead to achieve low latency to serve I/O requests. No priority quesues concepts, but only basic merging. Sio is a mix between noop & deadline. No reordering or sorting of requests.
Advantages:
Simple, so reliable.
Minimized starvation of requests.
Disadvantages:
Slow random-read speeds on flash drives, compared to other schedulers.
Sequential-read speeds on flash drives also not so good.
Cm7 compatible?

Because it has minimal overhead and doesn't do any requeueing, only processing in order, which most of the time is good in our case as we want to give the task in use priority, which sio does
This kernel is awesome! I love it.

Question what governor for KT747 do you think gives best battery life and performance?
Thank you finally I know what those profiles mean other than the obvious performance mode...

i have tried every govenor/ io scheduler combination on different kernels and always end up back on deadline/ondemand.
It really depends on your needs and usage.
I am running KT747, 192 - 2106, custom voltage table, SmartassV2/sio -- Synergy.r71.
SmartassV2 can ramp up very quickly to meet demand and also attempts to ramp down quickly when demand lightens. You get a performance bias when you are interacting with the phone and a powersave bias when you are not.
As schedulers go, I figure simpler is better ... sio, all the way.
