I was trying to figure out which scheduler available in 'pimp my cpu' worked best...
my results were inconclusive, but I figured I'd post them anyway, maybe a stats geek will know better than me.
methodology:
set cpu scheduler using PMC, save settings as boot. reboot. using quadrant, run 5 benchmarks. repeat for each scheduler.
test enviroment:
LG G2x
rom:
Bionix 2 with Trinity kernel.
pimp my cpu settings:
max 1500 Mhz
min 500 Mhz
all speeds -50mv.
Results:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
raw results:
Code:
scheduler Run 1 Run 2 Run 3 Run 4 Run 5 average
noop 3475 3931 3840 4224 3942 3882.4
anticipitory 3275 4004 4103 4099 3876 3871.4
deadline 3394 4024 4119 4373 4021 3986.2
cfq 3669 3992 4053 3955 4077 3949.2
bfq 4321 4268 4035 4008 3579 4042.2
Cool, nice for you to take the time to benchmark the I/O scheduler. I always knew BFQ is one of the best I/O schedulers available, that's why it is usually the first technology I introduce with my custom kernels.
I noticed that when using bfq launcher pro was smoother but my phone would go up to around 80% of CPU usage.
So basically bfq has a smaller threshold and uses more of the cpu's power even for light tasks and that's way it benchmarks higher.
Hope that made sense lol

Does anyone know how to enable the 1600Mhz undervolt on boot in SetCPU? I have to apply it every time I restart.

This is an excellent example of someones settings. It would be helpful if you mentioned what kind of performance/battery life you're seeing with these settings.
I just blindly set mine up the same way as in the screenies, so I'll have an idea after a day or two I think. I'll try to remember to come back and post what I've noticed.

I have been using No Frills CPU control and have no problem running Entropys daily driver which the highest clock setting by default is 1.2. I have run a lot of different ROM and I have had my best luck by setting my UC to 400. Governer performance and i/o scheduler noop or deadline. I generally get about 15 hours of battery life with this set up on most ROMs with the screen on for 2 hours. So.. if you feel the incredible need to OC by all means go for it.. but tis not necessary in my opinion.
I know there's already a battery life thread, but I thought it would be interesting to have one where people also included the amount of time their display was turned on for, since that seems to be the primary source of battery drain for me at least. Also if you wouldn't mind posting the average brightness it was set at, as well as any custom rom, kernel, or battery saving techniques you're using, that would be cool as well. And if you have a really long display on time, like over 5 hours, maybe you could include a screenshot fort verification too if it's not too much trouble. Thanks!
The most I've ever got is about 5 hours or so of display on time at around 25% brightness with sky ics 7.4, faux kernel 009m, -50 global uv, 1.5ghz CPU speed, and juice defender ultimate with 15 min sync interval. I can't find the screenshot for that one, but here's one that's almost as good:

These are my specs.
-QuickWiz Rom
-009m Faux kernel ( 1.242ghz max - 384mhz min / -75mV )
Undervolted using Fauxclock (Y)
-Froze bunch of bloatware using Titanium backup
SkyCoke ROM
Faux 009u Kernel
-100mV UV, 1.188 gHz max clock
No JuiceDefender or anything else extra besides whatever came with the ROM
what's the best setting for overclocking to 1400mhz without having reboot.
Raise voltages until it's stable. In rare cases, you may need to lower them. If none of this works, the SoC in your phone is too imperfect to clock that high (it wasn't intended to anyway).

okay, thanks for reply. i'll try it.

Thanks for sharing those infos...
May i ask for some more?:
System details [rom, kernel]
What app is the one you use on this screenshot?
what theme do you use?
Battery life with this OC?
Thanks a lot
1. rom : http://forum.xda-developers.com/showthread.php?t=1399035
kernel : http://forum.xda-developers.com/showthread.php?t=1036996
2 hold volumen down button + power button for 2 secound in same time..
3. http://forum.xda-developers.com/showthread.php?t=1531222
4. i think it same as 1000 mhz "OC" , because i have same voltages for 1000 and 1320 mhz..
i meant what application are you using to set the voltages... sorry i wrote the question the wrong way

Ok can anyone else confirm. I used cpu spy and other variouse kernel tuners to see that all 8 core will not go past 1.5 GHz. I am on the tmobile 920T and others are not going past 1.5. I am not coplaining about performance but if the exynos cpu is not putting out then we have a problem.

It's only showing the A53 cores speed and not the A57 cores.

Look at the better battery stat screenshot. Time in state for all frequencies has a highest level on 1.5ghz only.
I did benchmarks too and still not passing 1.5ghz.
There is no problem ,CPU spy cannot read the frequency correctly for a BIG.little CPU
It shows frequency for little([email protected]) cluster only ,not the BIG(A57) cluster which goes up to 2.1Ghz.
P.S Hopefully you understood this

Side Note:
I do believe its big.LITTLE though? Or am I off base. Could've sworn it was this way though. One of those odd things I remeberd because of the slight irony.

I hope this is 100 percent true. I even looked at trickster mod and it wouldnt let me set the frequncies higher than 1.5 either.
Since I see so much Ignorant in the Battery thread, I like to point out (rant) some things..
1. A person 6 hour of Screen On Time usage is different from person to person.
2. Temperature can have a great affect on battery life.
3. Signal strength can have a great affect on battery life.
So with that in mind, I suggest everyone try to do a PC Mark bench, it is fair and give people a much better idea of what of what they should be getting. To do this test here are the few settings you need to set
1. BRIGHTNESS AT 23-25% (EYEBALL IT)
2. Wifi on
3. do not disable Mobile data or sync
4. Clear all RAM before start
below are the CONTROL numbers from a stock rom (pictures are from greenbot.com)

Below is my stat, using arter kernel and foreverloco rom. (I DO UNDERVOLT MY KERNEL)
Is this ok? Running skyhigh 2.1 and darthstalker v4 rom. A57 cores @ 2.4ghz and gpu @ 852mhz with a -75mv uv all accross the board.
I ll post my battery result as soon as i can, meanwhile here s my previous battery result i got a few days ago... http://forum.xda-developers.com/showthread.php?p=63851201
Here s my pcmark battery score too. I started it from 90% after already using the phone for a whole hour (sot of about 1h6mins)
ran pcmark again with skyhigh 2.3 ...running at 2.4ghz a57...
