[Q] faux's kernel or cyanogenmod 7 rc3's stock kernel?

I'm torn between the two kernel's. Through your own experience, which kernel is better for performance and which for battery life? with the cm7 stock kernel i can get around 2700 in quadrant at 1.5ghz but i heard people were getting scores in the 3000's with the faux kernel?
Any help would be greatly appreciated!
P.S. why do i seem to get lower scores on performance governor than ondemand?

Faux is what I use. Don't base your phone on quadrant. Its like cake. Looks delucous.. but the cake is a lie.
Its a general idea of a phones performance.. not the end all be all.
Both work well... but faux has newer wifi drivers that greatly increase range and performance.

as stated above Quadrant Standard is just a starting point. It lead nothing to the true facts of how well a phone preforms.
Couple of things to consider.
1) Zinx has created CM7 around the kernel that is installed with the ROM. If you need help you will get more help directly from the developer using their kernels, This goes for any ROM.
2) If you opt'd into the feedback program you will be doing so with false information. You'll be giving feedback based on "product a" when in all honesty your using "product b"
3) overclocking the phone is not always the best thing to do. Sure it's nice to show off and say "hey looky what i can do" but when the rubber meets the road their is no real benefit other than cooking the battery. And keep in mind what happens to things when they get hot, they expand. And when you are pumping that much extra into and out of a processor they will expand which will wear and tear on the motherboard and solder joints.
Personally i'd just keep the stock kernel @ keep it at most 1017 unless you plan on showing off, then moving back ASAP. and for what it's worth i typically run my MyTouch @ 768Mhz.

neid, 2 questions!
1. I want to underclock to 768 as well (never messed with CPU settings before) on CM7 RC3 using the system built in setting not set cpu, have you seen any performance degradation?
2. when I revert back to stock from my nandroid, would the CPU be throttled back to default settings or will it stay at 768?
Thanks

1) on my phone, i use 768Mhz day in and day out, Fruit Ninja, Angry birds, Browser, dialer, navigating the phone in general everything performs EXTREMELY well. I've not had any complaints. just go to settings > cyanogen > performance > CPU > max > 768. Since Cyanogen is a lightweight ROM it doesn't have to push though all the bloat that MySense brings so we can scale it back and still get good results.
i personally do not care for Quadrant scores. but i know some people live by them so i've attacthed a 768Mhrz and a 1016Mhrz Quad score. The names will be the set speed.
2) the CPU speed will revert back to what ever you have it set as on that ROM. So if you left it 1017 in your Nanadroid it'll be 1017 when you flash the restore.

[Arrows - Guide] Best Aosp GB & ICS Roms [Updated - 1/22/12]

Feel Free to post and give feedback ^_^
Also feel free to Vote the thread ^_^
Q&A is in Post 2
_____________________________________
Hi Everyone, Arrow here and this is my guide to find what is the best aosp setup for your evo or android. It is true when people say "every phone is different." However there is an average of people that get similar results. At the moment people have different interest such as some people want performance and some want to improve their battery life. Of course certain people want both but only some get both.
*Remember what i put here is an average and may be different on your evo*
AOSP GB ROM'S: Ok so to start off, these are aosp roms still being updated as of now.
CyanogenMod 7 (CM7) - The most famous aosp rom out there, all or almost all other aosp roms are based off of this rom. This rom has a stable rom and experimental nightly builds. Anyone will tell you that you can't go wrong by choosing this rom. and believe me you will enjoy it.
CyanogenMod 7 Thread
Miui - This rom has the longest battery life and is very customizable. This rom is based off of CM7 and is an excelent rom. However unlike CM7 this rom does not have 4g so if you are willing to sacrifice 4g then believe me this is your rom.
Miui Thread
Gingerbread Evo Deck - Ok so although CM7 is amazing decks gb rom has said to be the exact same thing but giving off better battery life. other then that it is pretty much the same thing with some minor tweaks and some bloat ware removed.
Gingerbread-Evo-Deck's Thread
Xplod E4G - Team Nocturnal designed this rom and it is pretty much CM7 with the Sony Launcher + their apps. This rom will give your phone a nice cool feel that other people don't have. If you like a lot of eye candy then get this rom because it is CM7 just with a different look and feel.
Team Nocturnals Xplod E4G RLS1.2

using Xplod: there's a 50/50 chance the new tiamat kernels [4.0.7+] may not boot, in that case, they should use 3.3.7.

ICS(mod7) - Team Blaze designed this rom and you can consider this rom like Xplod E4G, a rom just like CM7 with some minor tweaks but with a different look and feel. None the less this rom has something very special this is the closest rom to being like ICS (Ice Cream Sandwich). I 100% support this rom because they are doing the best they can to make this rom look and run as smooth as ICS. so if you want to look like your ahead of the game definitely get this rom.
ICS(mod7) Thread
AOSP GB Kernels: These are three kernels that i know of, if you know of more please let me know and i will add them.
Tiamat 4.1.0 - This is the latest kernel made by Tiamat and this is the only aosp kernel still being updated. This kernel on average gives people great performance but lacks on battery life. The main Governor for this kernel is SmartassV2 which is a balanced governor, good to turn on your phone and good to use on a normal day to day bases. For this kernel i do recommend using this governor. It does have SBC and Non-SBC kernels. *Side Note* (Some people say Tiamat 3.3.7 works better for them and is also known as the LEE Kernel because it was awesome like Bruce Lee and looks like Lee backwards [337])
Tiamat Website I also put the Zips in the Attachment (At The Bottom)
Savaged-Zen - This kernel is no longer being updated, however it is still amazing this kernel seems to be Tiamat's competition. Where Tiamat lacks on battery Savaged-Zen does not. However it's performance is not as good as Tiamat. This Kernel comes in two version BFS (Brain F***ed Scheduler) and CFS (Completely Fair Scheduler). BFS is said to give better performance and CFS is the normal kernel. This kernel only comes with SBC however you may download "SVZ Manager" which will allow you to turn SBC on or off. The main governor for this kernel i believe is on demand However i use smartass and a lot of people us InteractiveX.
Savaged-Zen CFS sbc I also put the Zips in the Attachment (At The Bottom)
Savaged-Zen BFS sbc in attachments (At The Bottom)
SVZ Manager I also put the Zips in the Attachment (At The Bottom)
GoDm0de - This Kernel was made by toastcfh and is no longer being updated. It is non-sbc and in my opinion definitely the best non-sbc kernel. This Kernel has insane battery life and a pretty good performance. If you do not want to use an sbc kernel i recommend for you to 100% use this kernel. The Governor for this kernel is set on on demand (i think) however i got the best battery/performance using Interactive.
GoDm0dE Kernel I also put the Zips in the Attachment (At The Bottom)
AOSP ICS ROM'S:
ICS rom by: the_Plattypus and it is still in Alpha testing. however the development for this rom is moving really fast so hopefully a beta will come soon.
EVO 4g Ice Cream Sandwich from source
ICS-evo-deck: This Rom is by kushdeck, After testing out Decks ICS Pre-Alpha 4 & 7 rom i conclude that although it is a alpha it can easily be used as a day to day rom. extremely fast and very snappy. only thing that i found not working was the camera. (Now on Alpha5)
[ROM][ICS][1-11-12][WIP] ics-deck-evo [alpha5]
All Decks ICS Pre-Alphas
All Decks ICS Gapps
AOSP ICS Kernels:
Jaredthegreat ICS - jared has the most advanced ics rom which is in beta 2 but does not have a working camera to check this rom go here:
[ROM's] -ICS- 4.0.1-4.0.3>[AOSP]<--~B.2.0~
Will post them when they are released!!!
Rom Manager/Kernel Manager:
Rom Manager: This is an app from the android market and is extremely useful for pretty much anything. you can back up your rom, you may go into boot loader and you can check if certain roms such as "CM7 Nightlies" have been updated. However people do prefer Amon Ra for flashing, which is another plus of Rom Manager it allows you to flash alternative recovery, which will flash Amon Ra for you.
Kernel Manager: This app was working before but has stopped now, however if it does start working again what it had was pretty much all the kernels that you needed for any rom. this app would allow you to flash a new kernel immediately by going to the kernel you want to flash.

Reserved
Q&A:
Q: What is SBC?
A: SBC stands for super battery charger. SBC is trickle charging, It stops your battery from dropping from 100% to 90% right when you take it off the charger. Some say that it harms your battery but i haven't seen any harm and plus it only costs $5 to get a new battery on Amazon.
Q: How to set up and flash your roms and kernels?
A: well my friend "Crossrocker" made a guide for this with everything you need. so just click to go to his thread. [GUIDE||Oct/23]Best AOSP(CM7|Decks|MIUI) configuration.
Q: What is the difference between governors?
A: This Thread by "RJackson" explains it all:SetCPU governors (explained)
But if you're too lazy to click it here they are:
As explaind by RJackson:
ondemand - Available in most kernels, and the default governor in most kernels. When the CPU load reaches a certain point (see "up threshold" in Advanced Settings), ondemand will rapidly scale the CPU up to meet demand, then gradually scale the CPU down when it isn't needed. - SetCPU website
conservative - Available in some kernels. It is similar to the ondemand governor, but will scale the CPU up more gradually to better fit demand. Conservative provides a less responsive experience than ondemand, but can save battery. - SetCPU website
performance - Available in most kernels. It will keep the CPU running at the "max" set value at all times. This is a bit more efficient than simply setting "max" and "min" to the same value and using ondemand because the system will not waste resources scanning for the CPU load. This governor is recommended for stable benchmarking. - SetCPU website
powersave - Available in some kernels. It will keep the CPU running at the "min" set value at all times. - SetCPU website
userspace
A method for controlling the CPU speed that isn't currently used by SetCPU. For best results, do not use the userspace governor. - SetCPU website
Interactive - The 'interactive' governor has a different approach. Instead of sampling the cpu
at a specified rate, the governor will scale the cpu frequency up when coming
out of idle. When the cpu comes out of idle, a timer is configured to fire
within 1-2 ticks. If the cpu is 100% busy from exiting idle to when the timer
fires then we assume the cpu is underpowered and ramp to MAX speed.
If the cpu was not 100% busy, then the governor evaluates the cpu load over the
last 'min_sample_rate' (default 50000 uS) to determine the cpu speed to ramp down
to.
As explained by MDJ:
SMARTASS GOVERNOR - is based on the concept of the interactive governor.
I have always agreed that in theory the way interactive works - by taking over the idle loop - is very attractive. I have never managed to tweak it so it would behave decently in real life. Smartass is a complete rewrite of the code plus more. I think its a success. Performance is on par with the "old" minmax and I think smartass is a bit more responsive. Battery life is hard to quantify precisely but it does spend much more time at the lower frequencies.
Smartass will also cap the max frequency when sleeping to 245Mhz (or if your min frequency is higher than 245 - why?! - it will cap it to your min frequency). Lets take for example the 998/245 kernel, it will sleep at 245. No need for sleep profiles any more![/QUOTE]
As explained by teh roxxorz:
Lagfree - like the performance governor. It will scale the cpu to higher frequencies when needed, but not to 100% like performance, so you'll get a lil better battery out of it
SmartassV2 - A smarter smartass governor. Code was re-managed/removed to make it more optimized, and have better scaling performances
InteractiveX - a better interactive governor I believe; low scale cpu settings, for texting, browsing, ect, nothing intensive. I wouldn't use it for emulators, ect.
Q: Do you need PRL/Profile/Radio updates? Do you need to go back to sense based to do these still?
A: No you don't have to go back to sense to do these and you don't have to do these because Rom's will come with what you need. None the less if you would like to update your radios here is a thread by "Calkulin" where he keeps the latest radios updated: [ Radios ][ 9-5 ] All EVO Radio, WiMAX, PRI, NV & HBoot versions
Q: Does HDMI mirroring work on these roms?
A: As of this moment Miui and CM7 both have HDMI mirroring working, and sense all the other ones are cm7 with some tweaks they as well have HDMI working however from what i have read the only one that has not had problems with HDMI is Decks Gingerbread Rom
Q: Are all other major features (4G (except for Miui), bluetooth, front & rear camera, GPS, apps such as Netflix, Skype, Google Voice, Sprint Visual voicemail) all working at least as well as on a Sense or stock ROM?
A: Yes everything is working, however on CM7 and i presume on some others you also have to flash a gps fix which you can get from this thread: [GUIDE||Oct/23]Best AOSP(CM7|Decks|MIUI) configuration. and the Voicemail seems to have some issues for some people but works flawlessly on Decks with it's gapps + Voicemail which you may also get from this thread: [GUIDE||Oct/23]Best AOSP(CM7|Decks|MIUI) configuration.
Q:My wifi is connecting/disconnecting after a second, what should i do?
A: This answer was given to me by "teh roxxorz." This has nothing to do with your rom or kernel, do this:
Back up everything into Titanium Backup
Boot into recovery
wipe cache, Dalvik, and pretty much everything
reflash your rom,kernel and gapps (or if you would like to check out some other roms and kernels just click on the link in my sig)
once you've set up your phone download Titanium Backup from the market
in titanium backup restore all your apps ONLY!!! (don't get apps w/ data - only get apps, and do not get system data)
after this your wifi should be working just fine
Q: I am having wake issues?
A: Here is a Guide made by JBabey[FIX] Wake Issue (Android OS) - Combination of Radio/PRI/NV/Wimax/GPS !Solved!
Q: Can i make my 3g speed faster?
A: Yes, This answer was given to me by teh roxxorz:
You need to flash a sprint sense rom. I emphasize sprint because it won't work on the sense 3.5 roms, as they're all ports of other non sprint roms.
1. Flash sense rom
2. Obtain your msl, download msl reader from market, use it, write it down
3. type in ##3282# , input your msl (you can get this from the app msl reader)
4. Click edit mode > advanced
5. Scroll down to HHTD proxy port and address
6. Change the proxy port to 0 and proxychange the address to 0.0.0.
Q: How can I fix my GPS?
A: This answer was given to me by teh roxxorz:
- flash a sense rom
- open up the dialer
- Type ##GPSCLRX# or ##4772579#
- Your enter your MSL at the prompt
- Your phone will soon reboot > done
Q: Is there a guide like this but for sense roms?
A: Yes if you are looking for a sense guide rather than aosp then check out this thread by tropicalbrit
Q: What is your setup at the moment?
A: Rom - Decks 4.0.3 Pre-Alpha 7 ICS Rom
Kernel - Stock
Governor - Conservative
CPU Max/Min Frequency - 729/128
IncrediControl (app) - (-100) [I get to (-100) by first doing (-75) and leaving it there for 3 days and then I do another (-25)]

Also, you should also disclose to people using Xplod: there's a 50/50 chance the new tiamat kernels [4.0.7+] may not boot, in that case, they should use 3.3.7.
And any reason you were gona message me?

Hi,
Thanks for guide... I am considering changing from
my stock rooted ROM, so very timely for me!
Some features that you don't mention or summarize
that may help me and others.
PRL/Profile/Radio updates? I believe you need to
go back to sense based to do these still? [yuk]
HDMI mirroring?
Are all other major features (4G (except for Miui),
bluetooth, front & rear camera, GPS, apps such as
Netflix, Skype, Google Voice, Sprint Visual voicemail)
all working at least as well as on a Sense or stock ROM?
Thanks in Advance,

[Q] Performance difference from different kernels on different roms

Hi,
I've noticed a huge performance difference between kernels and the roms they're used with.
For example:
I was using AOKP and Franco kernel and got around 20000 antutu points, I've switched to Carbon Rom (because of the build in pie control) and Franco kernel and only get around 13000 points, that's a huge difference.
As a test I've installed Matr1x-kenel on Carbon and get around 21000 points.
I really like Franco-kernel and all the tweaks it offers but don't like the huge drop in benchmarks, I know benchmarks are not a real representation of actual performance but it's still a big difference.
This also occurs in Quadrant and Geekbench.
So my question is why does this happen?
Aren't most roms supposed to be compatible with most kernels?
Thank you in advance.
Best regards.

I can't answer your question as to why that happens (no doubt someone else will) but you seriously should just stop bothering with benchmarks and use your own eyes and experiences as a measure of how good a kernel/ROM is. I doubt you could find a kernel which made the phone visibly slow or that affected usability so I don't see what your concern is tbh.

Thanks for your answer.
Yeah, I read that a lot on XDA, don't trust benchmarks...I understand that but they must have some meaning.
I mean, if not why do they exist or do people bother using them?
To be honest I don't really notice any real performance difference between most kernels I've tested.
Best regards

some roms include many optimizations(like skia/dalvik, krait optimizations, and others), while some dont. its not thekernel thats crapping out on you, its the rom.

your eyes can be decieved.. they can see whats happening in the ui for example, but you can not see the complex calculations that are being performed or how your cpu is really performing. you can have a slow device whos ui is quick.

OK, I can understand that not all roms are equal but why does changing the kernel have such a seamingly big impact?
If a rom is bad to begin with it should stay that way no matter what kernel you use with it.
Offcourse what do I know, I'm not a developer so my knowledge on the subject is limited.
I'm just trying to understand what's going on...

kernels vary too, and they impact greatly because they control just about everything in the phone, kinda like a brain. since the kernels themselves vary, one kernel might be better set up than another to deal with certain code from a certain rom. and then also, every phone reacts differently to each kernel(and roms to a point). thats why its recommended to try out different kernels, combos. only then you can find the perfect combo for you/your device. what works great for somebody, can be lousy for another.

OK, so if i understand correctly it boils down to this:
1. You can do benchmarks but don't base your opinion on just the benchmark scores.
2. Roms can vary greatly in optimizations and efficiency of coding.
3. Kernels can also vary greatly in optimizations and efficiency of coding.
4. There's no such thing as a "best for everyone rom/kernel combo".
5. Not all roms/kernels play equally nice with each other.
6. Play around with as many roms / kernels as possible and decide what works best for ME based on MY experience.
Thanks for the advice.
Best regards.

Its been well over a year since I ran any benchmark of any sort but I tested Franco and carbon because that's what I'm on and you mentioned low scores. I'm on Franco m3 with some tweaked settings and carbon nightly from 7-5. Antutu gave me 20636. I'm using stock CPU and GPU frequencies.

Maybe the nightly Carbon rom is more optimized?
I'm on Carbon 1.7 Stable and used Franco nightly 162 to test with.
When I benchmark I try to be as consistent as possible ie same temperature, performance governor, airplane mode etc.
I even cooled my Nexus in the freezer for some minutes to eliminate thermal throttling (yeah I know, watchout for condensation) but still got the same low scores.
Best regards.

It might be, I didn't do anything special. I left all my background apps running, didnt close anything in the recents, didn't cool the phone first. I just downloaded it and hit start. I use the interactive governor tweaked a bit, and I also tweaked the hotplug settings so it more readily onlines all 4 cores instead of waiting for some of the higher loads to trigger it.

Well, I had to try it myself so I did a factory reset, cleared system,data and dalvik, installed latest carbon nightly.
With stock kernel I almost reached 21000 points, with franco I barely get 17000 points.
Very strange...
edit:
I stand corrected, did a second benchmark and am now getting 20880 points...

are you benchmarking with your cpu speed benchmarked set as highest and lowest cpu speed? you should. if you dont put the same cpu speed as highest and lowest then itll scale up and down. if it scales, you dont actually know what speed its testing and it gives you inconsistamt scores. you want the cpu speed to be the same throughout the test.

When I benchmark I set the governor to performance, this should keep the cpu running at maximum speed without scaling unless I'm mistaking...

meh, performance is the worst for benchmarking. its such a deceiving name. try either ondemand or interactive. set your cpu speed to be the same high and low.

Tips to increase performance and increase battery life |Xperia X8/W8

Hey people, this is my first post.
So basically this post is for people still using xperia x8 / w8.
TIPS to increase performance :
1. Install a custom ROM (with a custom kernel). It's no use installing a ROM on stock kernel because it's not very fast and battery life is low too ( I like Minicm7 and Minicm10)
2. After installing the kernel and rom, install a nice launcher. (LauncherPro for gingerbread and nova /apex for ice cream sandwich or jelly bean).
3. Tweak cyanogenmod performance settings : increase vm heap size, allow purging of assets, disable surface dithering, set cpu governor to smartassv2. Overclock if you want but not too much.
4. Use v6 supercharger script. (easy to follow and works great). Do it only if you have custom kernel, because on stock it asks to update busybox which soft bricks the phone).
5. Use autostart manager to remove unnecessary apps from boot.
6. Install apps that you need.
7. Enable "long press to kill apps" in development and kill after you use them like browsers etc.
8. Don't use task killer.
Battery life tips (I assume you are on custom ROM with custom kernel) :
1. Use setcpu and enable profiles. Make the following
A) Screen off - Set Minimum and maximum values of clock the lowest.
B) Battery levels - Choose the maximum to any value below 600 mhz but above 320 when say, the level is less than 40 percent or maximum 480 when the level drops below 50 percent.
2. Make sure you uninstall Dsp manager with titanium backup or root uninstaller.
It sucks lots of battery.
3. Don't set auto brightness.
4. Keep vm heap size to 32.
5. Set governor to on-demand using set cpu for all profiles. AS WELL as for normal usage. (where there are sliders)
6. You may use antutu battery saver. It may or may not work for you.
7. Use v6 supercharger script.
That's it. Press thanks if I helped.

I appreciate you for the effort you made.
But there are already many threads about it and also I think that most of the x8 users do have knowledge of these basic things..

Sir, Thank you for your review and the beer Yes I am aware of the fact that many people know about it but are tired going through many threads so I compiled a list. That's all.

Exactly this thread will be helpful for noobs much. Nice info :thumbup:

@op you may want to review some info. for example, for performance, smartassv2 isn't really the best choice (interactive or ondemand, anyone?). you may also want to remove v6 supercharger since noobs will ultimately ask a lot of questions about it (specially ics/jb users). conversely, ondemand is NOT the best choice if you want to save battery. it has a hair trigger that jumps to max freq and stays there for a long time (like interactive but with different conditions for scaling iirc). there are also lighter launchers than nove/apex/launcherpro. uninstalling or freezing unused apps can also help performance instead of trying to kill them (specially with apps that simply restart themselves). you also have the undervolt option. and updating busybox will not necessarily cause issues if you're on custom kernel. i've updated mine on cm7&10 without issues. i do think gdx (at least on stock kernel) bootloops if you update it. as daggre said, we already have lots of tuts about this, so it would be best to give accurate info or else it will just confuse users.

Hey i heard that if i use my sd card for page file i can increase ram or something like that but is it safe i heard that sd card life will get decreased

Yes you can use Swapper 2. Useful only if you use class 6 SD card or above. otherwise no use.

Sorry for the mistakes. I wrote smartass v2 because interactive sucks too much battery and isn't practical to use. I would like to delete the thread. I'm new here so please tell me how. I will update the facts and then write

you'll have to ask a mod to delete the thread. why not just update it though? it's a good thread for new guys. just update some info and you're good to go.

Alright, I'll update by Monday. Thanks

Haha, thanks for the tips :good:

Gamer Rom

I Need the Best gaming Lollipop Rom for I9505 with great performance and Battery life ?

That would be AOSP rom by the JDCTeam.
Make sure you set alucard kernel to the extreme performance or performance profile if you want better performance in gaming.

"great performance and Battery life ?" Performence or battery life! 5.1.1 CM with Alucard Kernel

if you get an alucard kernel in your rom then the raising the minimum clock speed to 810 khz on all four cores and the minimum for GPU speed to 200 khz it will help.
*gentle fair sleepers off
*arch power on
*CPU governors to ondemand or alucard with alucard hotplug
in developer option hardware overlays to off.
personally I think ktkernel was better with more options but you'd need to stick to AOSP 5.0 for that or lower

If he were to stick to older android versions (5.0 and lower) then he might aswell get KT kernel, which gives him the posibility of overclocking the CPU and GPU, something that is missing from the other kernels right now.

GPU overclocking isn't really stable, it actually takes away from the gaming experience.

How can increasing the GPU frequency, and therefor the performance, be bad?
If you overclock it too high of course it is unstable. But you should be able to take around 500 MHz easily.

I can't remember the steps you get in kt but I'm pretty sure the uppermost ones were next to unusable, 500 is only just above the standard speed.
the games are always going to have a fixed system requirement levels based on the hardware we have so there isn't that much to gain over optimisations for our roms I feel...
I always judge a rom based on how well it can play shadowgun deadzone. most untweakable kernel rom combos aren't so great fresh out of the box.

Well, I used KT kernel in the 5.0 days. I ran a gaming profile created by ktoonsez himself, which had GPU overclock, and ran stable all the way.
I usually judge a rom by how fast it opens the settings app. This presumes that the app was fully closed, otherwise it will just switch to it, wich is a lot faster than actually opening it. Also, animations are all off.
So, between the pressing of the icon and the actual opening of the app there will be a black screen (if animations are turned off). The longer you see that black screen, the slower the rom is.
