If you are in the extreme undervolt version, maybe its because your phone cant handle low voltages. Lots of people are getting this problem. (its normal, each phone has its limits) So the only remaining option is to flash the non-extreme kernel and set the voltages manually via incredicontrol app.

[Samsung Galaxy W I8150] hadidjapri:
BFS gives higher priority for foreground process, that's why game runs smoother. but this also have min side which is giving lower priority to background process that implies to a lag to background process.

scrolling smoothly between each background apps is what a multitasker looking for CMIIW
[Samsung Galaxy W I8150] honeyx:
What???? Scrolling smoothly between background apps???? So are you scrolling for example between the clock and the keyboard or the services?????

That´s absolute nonsense!!!

The app where you are scrolling atm will be running in the FOREGROUND. No matter it´s the launcher, the settings, the facebook app, your contacts or whats ever.

Many apps or processes that a running in the background even do not have a User Interface, so where do you want to scroll there???
[Samsung Galaxy W I8150] hadidjapri:
hmm i guess i use the wrong term "scrolling" . i mean like you are running music player , facebook , sms, and twitter and then you want to change the song you are listening to . it will be s*** if the music player lags and change the music after 10 seconds after the next track command issued

anyway thx for correcting me :D
[Samsung Galaxy W I8150] honeyx:
Ahh ok. You mean task switching.

Hm well..... the BFS should be still better than CFS for this, as the CFS is checking how often an app or service was used b4. The ones that are used often get higher priority and the ones that are used rarely lower priority. So the BFS is more "fair" than CFS in sharing the surces and CPU time.

The reason why Arcos beta 3 is faster than beta 2 is not just that the BFS is giving higher priority to the apps and tasks that are currently running in the foreground, but also because the background processes do not get the higherst priority just because they are running all the time. So this is like said more fair to the apps that you will launch and expect to run fast and smooth.

You for example do not need your google account to be synced all the time while playing a game, making a call or running a navigation app. They still are running in a multitasking environment, but at lower priority when other apps need higher priority.

Windows 7 mobile for example is completely disabling background processes while an app is running in the foreground. So this is not a real multitasking OS like Android.
[Samsung Galaxy W I8150] hadidjapri:
hmm i start to understand. something i still confused about is you said that bfs is "more fair" than CFS so it should be running multitask better than cfs right? is it only in single core processors or universally?

completely disable background apps? :confused: then how it still can be called as smart phone if it can only run 1 process at a time?
[Samsung Galaxy W I8150] frozonecom:
Sorry, v7.3 BFS Extreme Undervolt is working on MIUI. Adrenaline Engine and Adrenaline Boost conflicted with the kernel and caused instability on the ROM. Smooth! THanks for the Kernel! More updates pleasE! :)
[Samsung Galaxy W I8150] honeyx:
There is a simple rule that says BFS is more fair than CFS on devices with a single core CPU and CFS is better for multicore CPUs. So related to our device BFS is better for running multitasks and foreground apps. Devices with a multicore CPU require a bit different strategy and there CFS has it´s benefits against using BFS.

Regarding Windows 7 mobile thats the main reason why I decided to buy an Android device. So no windows based smartphones for me unless Microsoft changes this again. Teir challange was to make foreground apps running absolutely smooth like about Apple is doing. But Apple isn´t disabling background processes completely. So this is a real pain what microsoft did and a step backwards.
[Samsung Galaxy W I8150] UltimHero:
AFAIK widows phone 7.5 and higher supports and does multitasking !
[Samsung Galaxy W I8150] honeyx:
Yes it does but it disables background processes completely while an app is running in the foreground. And that´s not a fully multitasking environment anymore. Unlike the older windows mobile versions that don´t do this. You should do some reading about it and what the restrictions are and will understand why it´s acting more like windows 3.11. So do some reading but not just knowing it "as far" because this only means you are not familar with it´s cons and lacks in multitasking. There is no doubt Microsoft wants you to still belive it´s a fully multitasking OS, but that´s not the case and a step backwards. At least in the mobile section.

But well this is quite off topic. So let us stop hijacking this thread. This can be discussed in an other thread.

Hey Pep, which version of this kernel that have u flashed?? CFS or BFS?? the normal or extreme version??

Actually i've already flashed the BFS normal version, but after that i encounter some FC issues with many of my apps.

I sure did follow the instruction correctly when i flashed it.

Do you mind to share the way you flash this kernel actually??

Thanks a lot Pep...:p
[Samsung Galaxy W I8150] pepoluan:
I see.

I think RemICS -- or, to be precise, a component of -- is not compatible with this kernel.

OR

Your hardware for some reasons became unstable when undervolted.

I use BFS Normal, not Extreme.

Here's how I in general flashed it last night:

1. Turn off the phone, remove the SD and copy everything in it to my PC.

2. Repartition the SD with my PC, making sure all partitions are aligned to 16MiB. I also took the time to create a second partition.

3. Copy the updatezips of CM9b3, GApps, and CastagnaIT to the root dir of the 1st partition. Only these 3 files were in my SD. No other dirs, no other files.

4. Boot into recovery, wipe data, cache, system, dalvik-cache, and internal SD

5. Flash CM9b3, flash GApps, reboot

6. Swap SD as soon as the Initial Setup process completes, reboot

7. Reboot again into recovery, flash CastagnaIT's kernel, fix permissions

8. Boot the phone. Let it rebuild all system apps.

9. Reboot into recovery, and fix permissions one more time

10. Boot the phone, and... done.

Yes, it's a modded kernel. And I think it's his priority to fix all incompatibilities with standard apps that runs well on unmodded kernel.

But additional mods or tweaks on top of a modded kernel? Why should he concern himself with those? After all, the mods/tweaks you added on top of his kernel is *not* his creation, and they are non-standard anyways.

My advice : Stay away from mods/tweaks that you don't know *exactly* what it's doing. Especially with a modded kernel.

hsdpda protocol is not from the kernel but it's from the rom itself

What you get?

1. More governors

2. More schedulers

3. Undervolted (if you flash the UV version)

4. Less battery consumption (due to the tweaked governors)

5. You can overclock or underclock your cpu frequencies

6. BFS schedulers (if you flash the BFS version) (users say that BFS schedulers works better in our single core cpu)

And for hsdpa is not depends from the kernel but it is from the base rom (cm9 b4) yes it is have a big performance thanks to sir arco for his works

Any suggestions?
[Samsung Galaxy W I8150] 2g11:
No offence but that doesn't answer the question, from those using the kernel, do the governors/schedulers actually improve the user experience compared to the unmodded B4 rom? Will the rom be almost completely lag free? Will I now get 2 days instead of 1 day on my battery? This is what I'm asking, I don't mean to offend anyone especially the kernel maker:)

[Samsung Galaxy W I8150] reddvilzz:
What? You asked what you get with this kernel that is the answer. :confused:. This is a different questions. I just answered what you asked though. But none taken :p

Nope you can't get 2 days battery if you using any of the kernel especially when you have 3g on. If you have 2g on without data yes you can get to 2 days battery

For me the costum kernel works flawlessly and smoothly better than the stock that is my opinion after using it till now.

Don't hesitate pressing the "thanks" button :D
[Samsung Galaxy W I8150] pepoluan:
No offense taken :)

A completely Lag-Free experience is probably impossible with the W, since (1) it's single-core, so an out-of-control process can still lock up the CPU, and (2) the RAM is so low, sooner or later an app (games, usually) will force a purge of portions of the Android framework, portions that several minutes afterwards will be needed by the app, and the system slows to a crawl trying to juggle which modules should be swapped out to provide space for the needed portion.

HOWEVER

With proper tuning of OOM adj values + right selection of governor, lag-events are significantly reduced, since when the aforementioned thrashing occurs, the combination of BFS Scheduler + correct governor will drive the CPU at MaxFreq, allowing a (relatively) rapid reorganization of memory (compared to the performance experience of 'standard' CM9 kernel).

tl;dr : Yes, I *greatly* enjoy the real improvements CITK brought to CM9b4 :cool:
