Hey,
I decided to mirror your kernel:

Download speed is pretty good.
Let me know if you'd like me to remove it.

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.

Poll: Which governors do you use the most in your kernels?

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!

[Q] Draw Something Is HOTTT!!!

Literally lol...my processor goes crazy and reaches my temp threshold on SetCPU. I'm running Mik's 2.0, and i have minimum apps running at startup. i even log out of FB when i open the app. does anyone else have this issue where this app heats up your phone, and what did you do to counter it? Any info helps. Thanks in advance!
Whats your cpu speed set at? What i/o scheduler and what governor you using?

my cpu speed is only set at max 902MHz for the normal profile, and i'm using the x99 GB kernel. i don't believe i'm using any i/o schedulers :/ i only use setcpu to govern the cpu. i just had to research i/o scheduling when you mentioned it...wanna school me on what that is used for and if it would remedy my cpu heating up lol? thanks for the reply.
No frills cpu or antutu has a cpu control app available free on the market. Both allow you to change your governor and i/o scheduler... Ill get ya a good link about i/o scheds...

i actually just got done reading that same link lol! thanks for the advice on the app to use, couldn't find one. so with my specific issue here, what is your preference for the i/o schedule to use?
Your phone will tell you more about preference than I can... I personally use vr i/o scheduler and on demand governor...

thanks again man. i'll look into it a little more!
With x99percent kernel I use "cfq i/o" and ondemand set to 1.2 ghz max and 184 mhz min.
I'm on Sparks' at the moment, sio for the I/O, max: 1.4, min:384, using Antutu CPU
thanks for the suggestions! i downloaded the No-Frills app and set it to "cfq" and so far it has yet to reach the temps it did without the i/o scheduler. once again thanks for all the help!
Glad we could help... That's what we're here for.

because i got confused which governor and i/o sch to be set in no frills cpu control...as i dont know there use...

[HOW] How to solve lag in youtube videos!

To solve lags in youtube videos use BFQ as I/O scheduler. Its that simple
How does this affect video streaming?
A: BFQ causes less jitter as compared to CFQ and other I/O schedulers thus video streaming and HD video recording will be at its 'peak' with this I/O scheduler.
Enjoy! And hope this helps
Is this for cm9? I don't seem to have any trouble. Bfq is usually for battery life, not performance

Hmmm... yea. CM9 some ppl have this problem and that includes me! BFQ... it dependds... it does improve performance but not overall performace but it is very good for usb data transfer rate. It is also the best scheduler for HD video recording and video streaming. (because of less jitter as compared to CFQ and others). It is also an accurate I/O scheduler. Achieves about 30% more throughput than CFQ on most workloads too...

kernel which have no support of bfq can use vr instead..
the titanium kernel for example has noop/sio/cfq/vr

Vr i/o has a great performance yes. But it is super unstable. Recommend noop if no BFQ but anyway titanium kernel is only for GB and only ICS ROms has lag issues in youtube... so no point i guess?

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.
