Performance - Stock vs Custom - Galaxy Tab S Q&A, Help & Troubleshooting

So I have been testing a whole bunch of custom roms / Kernals on the Tab S 10.5 ( Wifi ) About now I have tried all the ones from here ( AOSP, AICP etc ) and no matter which I try the performance isn't as good as the stock Samsung ones. This confuses me ? They are bloated with Samsung junk, older builds and generally should be rubbish but here we are and performance simply isn't as good. Whilst the Antutu scores are higher the CM builds for instance simply aren't as fluid, pauses, stutters etc. As minor as they sometimes are annoyingly aren't there ( as much ) on the Samsung roms
In the end I stuck with the stock rom, debloated as much as I could and installed the Google Launcher from the market. It's a shame as I would love a stock experience but it's simply not as usable.
So, are we missing drivers etc ? There must be something in the stock roms which utilizes the CPU/GPU better. Any ideas ?

Those aosp/cm roms aint official at all, everything is just a port.

Well I don't know about stats, but the cm12 roms fly with no lag over stock.

[Q] AOSP ROMS as at Sept 2011

Hi all,
The Dev Forum seems to be pretty abundant with Sense-based ROMs at the moment, and I guess that's to be expected with 3.0 being everyone's new(ish) favourite thing, but not all of us are Sense fans and I just wanted to get people's opinions on the current state of play concerning AOSP ROMs and their latest versions, especially around battery life.
What have you used / are you using, and how do the current suite of AOSP ROMs compare with each other in terms of battery life (but other stuff as well)?
I'd love to hear about people's recent experiences.
Thanks.
This rom is the best aosp rom I've used yet. Blazing fast and amazing battery life.

I tried Gingerbeast, HydrogenMod, Hikari, CyanogenMod and Ginger S and I can't seem to get any of them to be 100% fully functional. I've had a problem with bluetooth not working, not being able to import contacts, the home button stops working, com.android.phone force closing, etc. I've full wiped, reinstalled, fixed permissions, etc, but I can't get any AOSP rom to work. Surely there must be a leak of the AOSP rom that HTC use before adding Sense and other HTC addons?
While AOSP roms are light wight and seem fast they will never compare to roms built off of sense roms. Why you ask. Look at the roms like CM7 and other AOSP roms, they have to use open source drivers that dont make full use of the hardware. Like wifi and blue tooth. Both lose 25% strength because of the Open Source drivers instead of using the drivers built for the Phone like the closed source HTC drivers.
Umm, apologies if I've confused myself out of sheer ignorance, but can't you just flash a custom kernel like Lordmod's excellent one, which DOES contain official DHD phone drivers?

Sense based kernels will not work on an AOSP roms
LM is a aosp kernel.
i don't see any problems with pretty much all of the AOSP kernels i have used (Most CM based ones, quite a few Miui Ones, and the default CM7). The Wifi and BT work, gaming is pretty good, and its also much less laggy (Sense based roms occasionally freeze for no reason. Its annoying with music playing)
The only thing i dislike about AOSP roms is the camera which doesnt have touch to focus video recording, but pretty much every other sense feature can be replaced by a free, custom app (LauncherPro is much better than rosie 3.0/.5, custom video players play more movies, etc.)
you could always flash a sense/rosie/app remover on top of a sense based rom

Unless you needed to connect to a spicific type of network or need BT to work a certain way you wouldn't notice it.

Yeah, not sure about that 25% statement, mate.
I've been running CM7 Nightlies or CM-based ROMS for a while now and, if anything, I've noticed a significant improvement in connectivity (in general) from what I previously experienced on Sense ROMs. I'm sure that Lord Clockan's excellent kernels have a lot to do with it, but anyway...
I suppose everyone's experience is different.
Hy,
I am also a HUGE fan of AOSP. Since I bought my DHD it had Sense for one day because I had no time to flash. I also spent some time comparing Sense vs. AOSP Roms, and can say that AOSP has better performance on my DHD then Sense and always used them with the kernel they come with.
Aosp all the way. My recommended roms:

Hmm Not sure that makes sense!

Some questions.

I was wondering if stock web browsering performance, is universal or about each Android version/Sense version? Like let me give you some examples, such as if you are running(on the HTC Incredible 2 of course) Android 2.3.4 with Sense 2.1(the stock ROM) or just regular Android 2.3.4 AOSP will the browsers on both of these different ROMs have different speed performance to load up pages(Using the regular browser that comes with the ROM). Another example would be how about the same thing but Sense 2.1 stock ROM on Android 2.3.4, VS a Sense 3.0/3.5 ROM on Android 2.3.5?
I haven't noticed any drastic difference. However, I've been using Dolphin browser since I got the phone (although I have very recently moved to the Chrome browser, which I'm not sure works on any Sense ROMs yet).
For me, the biggest performance issue is based solely on the strength of my connection, which should be the obvious contributing factor. But if it helps, I'm running the AOKP ROM and the stock browser seems to open quickly and load pages with ease.
I did some tests and found that the sense Rom stock is faster then the browser in CyanongenMod 7.
My two sense i have to agree with the previous poster, if your on wifi most roms/browsers are comparable. (though i dont like dolphin..)
Another consideration is whats included with the rom? Although obvious the less your running the better your browser app will preform.
You could try different radio / rom combinations to gain a better connection ..

CyanogenMod 10.1.3 - Best Kernel/ Rom??

I've tried out some great Roms such as , Resurrection Remix, Liquid Smooth, SlimKat and Cyanogenmod
But so far i only like CyanogenMod, v10.1.3 and whenever i upgrade to the next version 10.2.1 i feel as if it lost its smoothness and it has some lag every now and then and it sorta disappoints me.
I've been wondering , if you guys can help recommend me a Kernel to flash for this rom?
i'm looking for a kernel for this Rom specifically like or specific type
(Type1 )
Very Smooth or Fast
Great or Good Battery life,
(Type 2)
Mixed Somewhat Smooth and Somewhat Good Battery life
(Type 3)
Very Fast and Smooth , okay or below average Battery life.
i use my phone almost daily for just apps and some camera footage but i just want to know if theirs a good one that meets my asking.
also how do i flash a kernel? or well do i have flash the kernel before the rom in CWM or after i flash the rom then flash the kernel????
sorta n00b here
I've been also thinking....
I've been also thinking if theirs a CM ROM? or a different ROM , refering to like a muisic based phone or rom.
such as a Rom that include speaker tweaks or mods and make the sound better or the quality perfomance greater.
and during calls to make it louder or sound better aswell. but also including smooth and fast responsiveness. ive been noticing the FC or force closes in the other roms and sometimes my phone wouldnt wake up when i push the power button and that sorta grinded my gears.

Trying old Roms - Refreshing

I am just sharing my latest experience. I have a Galaxy S3 SGH-T999L and I have tried so many roms and love many of them. I tried a few different Lolipop roms and a couple of them worked really well with the exception of Open Camera freezing here and there. I then went back to a TW based rom that was very customizable and fun. The keyboard had a tine hickup that bugged me a bit, but I just had to replace it to have a great rom. I then decided to try some very old roms in the TW arena like Wicked. Cool rom, but that had a camera issue as well when I tried the KT kernel. The stock kernel may have been good for the camera though, but I didn't try it. I then decided to do AOKP and I almost forgot about them, because they stopped making roms for the S3. I loaded the rom and wow, a breath of fresh air. My battery lasts forever on that rom and a custom kernel. There are like no bells and whistles compared to Lolipop though. The dialer doesn't show pictures and stuff. It is simple, sleek, and fun. The best part is that everything works on the S3. The rom was very customizable for those times of course.
Here is what I am running if I didn't get my downloads mixed up:
- AOKP_d2tmo_jb-mr2_milestone-1
- 3.4.66-KT747-g1ded067
I can't believe this combo still soars without any problems
I keep everything simple though. I don't use things like FB messenger or Google Now launcher. I am keeping an eye on permissions and underclocking my processor a bit. Vanila music player doesn't use many resources and I was using others with my Loli roms.
Maybe I will run into an issue later down the road, but all is good for now. Have a great day! Just wanted to share.

Question AOSP based ROMS

hi there. any rom that is very good at gaming. tried many aosp based roms run the CODM and lack of graphics and very laggy.
All Vanilla Android Custom ROMs perform more or less the same.
But they're definitely better compared to MIUI.
If you're unsatisfied with AOSP ROMs, it might actually be your phone. ^^
