Poll: Which governors do you use the most in your kernels? - Nexus S Q&A, Help & Troubleshooting

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!

On-demand, I believe.
pretty shure its ondemand
Ondemand.
SOLVED.
It could be interactive got this from setcpu's site
interactive – Available in newer kernels, and becoming the default scaling option in some official Android kernels. The interactive governor is functionally similar to the ondemand governor with an even greater focus on responsiveness.

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.

[POLL] what cpu governor are you using?

Hi!
I would like to know what governor are you using and why.
Sent from my Nexus S using XDA
I was a fan of the good ol' "ondemand" governor for a while but a few days back I switched to "lagfree" - I heard of its good reputation somewhere inside the general sub-forum - and I ain't going back lol
p.s., You might wanna add a poll to this thread, it'll help, believe me
Hehehe I'm not sure on the list of governor available that's why I did not put an actual poll here.

My i9023 (Stock 4.0.4 and Matr1x v19 kernel) is currently running with the Lulzactive governor.
I've only had the last week to try a non-stock kernel (Matr1x v18.5), but so far Lulzactive sems to fit my needs well. It's clocked to 100/1200 MHz and everything feels very smooth and it doesn't drain the battery (that's the job of the S-LCD )
I've had good use of this thread which explains the different governors.

1000 Freq lags in ICS ?
Ondemand. I have tried several others (like lulzactive, smartassv2 and wheatley) but keep coming back to ondemand for the best mix of smoothness and battery life while still being stable. Wheatley gave me the best battery life a few Matr1x versions back but felt slow every now and then. Ondemand is good enough and stays stable.
Mmmhhh... maybe recent ROMS have already optimized it to run in that low freq. Before when early ics roms came out I have to over clock my cpu and always set it to performance governor so that it will run smooth.

I decided to give it a whirl myself. I toned down the CPU speed to 800 and the phone is still flying. I've been using it all day and no complaints. I guess now it's a toss up between lionheart and ol' reliable ondemand.

[Q] What is the difference between a kernel - governor - and speedtweak

Hello,
I am by no means a developer but have had a few android phones and today started thinking about what the difference is between the following...
A kernel
A Governor
And then how does speedtweak fit into the equation?
Seems like a kernel tells the different hardware in the phone how to work - then the governor is kinda like regulating how the processor works and handles tasks - but the speed tweak really confuses me - is that just kind of a way to regulate how the governor works?
Thanks in advance for your help and for being nice in your reponse.
You are right about what the kernel is doing. The governor only controls how the cpu goes from min to max frequency. A speedtweak changes some of the kernel parameters (most of the time).

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.
