Using ROMs: Performance increase?

I am considering using a custom ROM on the transformer, but is it worth it, I am mainly after performance increases. I see on a few that there are higher benchmark results, but does this actually translate into a real world speed increase?
I remember some custom ROMs for the original i9000 Galaxy S doubled the benchmark performance, but that was more down to "cheating" the benchmark than anything else, although it certainly was noticeable at times.
One of the slight criticisms I have of the TF101 is a slight amount of lag / lack of responsiveness occasionally - not a deal breaker, but if it can be improved then why not? Obviously not at the cost of stability though.
I think the SGS2 has spoiled me a bit here!

apparently there is a big increase (mostly from overclocking). i had the standard firmware for 3 days only, so I can't really tell, but one of my co-workers has a locked B70 and was wow-ed by my TF, the smoothness and speed of it.

Yes, I'm waiting too, to root it and put a cutom ROM on. I read, heard and saw the performance difference. Mainly from the overclock, but also thanks to kernel tweaks and stuff. So If you can root, do it

I've never been that keen on the idea of overclocking, as I prefer to have a bit of headroom, but I guess if it is safe and makes a big difference, then I would give it a shot. What would be a good middle ground for stability / speed ?

1.4 IMO is very stable and doesn't increase heat or use more battery but the real world performance is noticable. I have never run a benchmark so I can't give you any numbers. Just my normal use.

Cheers for the reply.
Is there any one ROM that stands out as being the best performing?

Contrary to what people think they all perform about the same. There is no source so everyone is building of the same stock rom. If you want the same look then go with Revolution. If you want a little tweaked then go with Prime (What I'm on). If you want the tweaks and a nice tools package then go with Revolver (What I was just running). All 3 devs are really responsive to problems
If you start from a clean base and don't restore any system data from other builds then they will all be fast. The real speed difference is in the kernel and those can be flashed seperately from the rom. Clemsyn is really putting out kernels this week. Some good. Some not so good. Go with whats right for you.
EDIT: I have actually installed all 3 roms in the last week and run them at stock and at 1.4 Ghz. They all performed exactly the same for me. They were all equally stable. I don't use benchmarks because they can be fudged.

I've used all three too. I notice huge improvements with webpage rendering. It's almost as fast as my laptop, where as before I avoided using the browser if possible. The ability to hide the status bar is a really nice addition to the latest version of revolver.
Edit: autorotate is also alot faster.

There is no such thing as an overclocking "middle ground" when dealing with mobile chipsets such as the Tegra. It's not like overclocking a desktop computer where the CPU will constantly run at the specified speed; mobile chipsets are pre-configured to utilize only as much power as necessary. For that reason I always ramp up my tablet to the max clock speed it can reliably handle, because then the governor will handle balancing between speed, stability, and battery life. My clock speed can range from 216Mhz to 1624Mhz, and on the interactive governor I can still achieve a good 8 hours of battery life from a single charge.
Of course that's not to say that you couldn't constantly run at 1624Mhz all the time, and I do sometimes lock it to that speed for games. But for much of the OS interaction, it's not necessary to run at full speed all the time, and you won't notice a difference even if it is locked at full speed. It just comes in handy every once in a while for things like loading apps, loading web pages, and playing games.

Overclocking Confusion!!

Finally figured out how to over clock my CPU/GPU on One X with CM11 KitKat rom. Bumped the CPU to 1809 (what I researched is stable) and GPU to 512. My Antutu benchmark score dropped from low 17k's to mid 13k?
Help please!! Could running Trickster Mod App interfere with Performance option in CM11....?

Trickster Mod isn't interfering with the performance, it just means your phone won't perform at its peak with those settings. Higher CPU/GPU clocks don't necessarily mean better performance, I've seen this through extensive personal testing. Dial the settings back to stock and increase the clock speed incrementally while testing after each increase, you'll reach a point where performance suffers, dial it back one notch and there you have your "peak" settings.
Unless you're doing some really hardcore gaming on your phone it's all pretty pointless. There's no advantage to overclocking in everyday use of the device other than to say it's overclocked, you just can't notice a difference, any noticed difference is more than likely a placebo. I actually underclock my CPU to 1242mhz to improve battery life and have zero negative response whosoever, no matter what I throw at it.

I agree with Tim here. I'm running cm11 on power saver mode, and it runs just fine. A little slow opening and closing apps, but buttery smooth for everything else.

Best CPU settings in Kernel Aduitor for good battery life

I am running MoKee with pretty decent battery life but am currently experimenting with reducing screen resolution and tweaking CPU & GPU settings (using Kernel Aduitor) to see if I can squeeze more out of a charge. Not really sure what the best settings are to maximise battery while keeping smooth everyday performance (I don't game or do any very heavy tasks or multitasking). I thought that it might be possible to get near SD625 stamina from the SD820 seeing as they are both built on the 14nm process, but the architecture is very different (ours has the quad-core big little set up with kryo, as opposed to the 625's octa-core A53 set up). At the moment I am trying it with the little cores left at default and the big cores max frequency down clocked by about 25%. I haven't changed the governors. I also down clocked the GPU max frequency a bit. Anyone have any advice regarding an optimal set up?

Not sure about the best settings but for sure I'm waiting for your feedback regarding this change and battery life. It should be improving it, but nobody knows how much.
Also I've noticed that in youtube if there is 720p or 1080p, the default setting is 720p (of course our screen is a multiple of 720p).
Are the pixels visible?

Couldn't see pixels with reduced screen resolution, even at 720p. Of course it's only rendering a lower resolution image then stretching it over the physical
1440p display. The result is just a softer image. Looks a bit strange, but 1080p wasn't too bad. However, didn't seem to have any effect on battery life and surprisingly at 720p I got a worse Antutu score than normal, so I have given up and returned to 2K.

I feel sorry for that I was really hoping for some way to increase the battery life a bit.

Hey guys... Today I found something interesting in our German Android forum. There's a group of people who are developing a great Rom for our device. It's just called the telegram Rom.
So the Rom will include scripts tweaks and a full working app for changing governors. So you will be able to get a much better battery life. The German guys talking about 20 to 30 percent extra power for our device.
The hole project behind this was founded here on xda but mainly developed for the Oneplus-3.
But in fact the whole workaround is working on any device that's running a SD820 processor.
Here is the link to the site
https://forum.xda-developers.com/oneplus-3/how-to/advanced-interactive-governor-tweaks-t3476589
So maybe you like to have a look. There are also complete explanations of how the SD820 works related to energy management and voltage at minimal and maximum clock speed!
I hope this can answer your questions.

Thanks for sharing Lizard82.
I follow the thread and use AKT... i am using the profile called Project Zhana & X.A.N.A v4.2. 14 hr sot is unheard of but I am getting close to 6hrs sot with xposed loaded which I am already impressed. It is is way better then what I used to get around 3 hrs sot. I am running revolution 21s rom which is very similar to EUI and not the most optimized rom with heavy battery drain. and I am happy that this phone finally has a good battery life. Appreciate Lizard82.

The sot really depends of what you do with the phone, and what apps run when the phone is on idle. I changed the resolution to 1080p but didn't notice any difference, so I went back to 1440p. There are tons of threads about kernel Adiutor, you won't have a hard time finding it

For best battery on Nougat I did this on Nexus 7.1 and AOSP 7.1 roms with BS kernel:
- Use rom that can use Black Screen kernel 2.1/2.2 or later
- Use kernel Adiutor to change CPU governor to impulse (or Darkness)
- Set value in Govenor tuneable (locate just under CPU Governor touch it to go inside to change value) : highspeed_freq to 307200, set Powersave_Bias to 1. I changed both BIG and LITTLE CPU core in kernel Adiutor.
- I think keep AKT profile on stock/unchange no need to set it is ok

Can somebody explain what I have observed?

Hi fellow S6 users! It seems like that I can only get great 3d gaming performance on marshmallow by flashing space x kernel. Hacker, nog33k, twisted and even arter kernel lags on 3d games such as real racing 3 and modern combat versus.
Even at the same cpu and gpu frequency, all of those custom and even stock kernel lags on gaming but not while on space x kernel.
I have also observed that smooth gaming experience can also be found in ressurection remix by @macs18max. FWIW, Lineage os by team nexus on the other hand, is very choppy in 3d games.
Can somebody explain why is this so?
(Please do note that all of my tests were done after allowing the device to cool down so we can cross out thermal throttling here)

Very obvious answer. Samsung makes their devices slower purposly just to make you buy the next gen even tho the old models are more than enough capable. You only can overclock the GPU with Kernel Auditor or app of this kind. Also you can "Turn on 4x MSAA" option i develower options menu.

Planned obsolescense seems to be the right answer I'm afraid. But the thing is that why can spaceX kernel be smooth in gaming at stock clocks mind you as to compare to other custom kernels which lags horrendously in gaming whatever the clockspeed you set the gpu or cpu. This laggy behavior in games can also be observed in stock kernel of marshmallow or nougat. It seems like the only exception (aside from marshmallow with spaceX kernel) is Resurrection Remix Rom by @macs18max which have excellent gaming performance!

Search logcats in the system buffer with
"SIOP_ARM_MAX"
"limitGPUFreq"
"limitCPUFreq"
after the phone slows down.
Is this it? SIOP_ARM_MAX as the reason looks more like power saving (low frequency, exits slowly after cooling).
First could be filtered with logcat -b system -s CustomFrequencyManagerService, others are random letters.
Search /system/framework/oat/arm/services.odex , might have a list of package names that are throttled differently.
Edit: could be about power saving, or people complaining that the device is hot or warm, or to try to prevent USB failure, or to try to prevent eMMC failure, or to try to prevent battery failure. Maybe not planned obsolescence because it's on the S8 too (but the hardware is better).

Kernel Comparison

Hi XDA community!
I was doing research in to the current custom kernels available for our phone. Pretty much every kernel developer advertises their kernel as having improved performance and battery. One of the problems I found is that it is quite difficult to compare the performance and battery of kernels without trying it out for a week or so. I thought for the benefit of not only myself (who doesn't have time to test every kernel), but for the community that it would be helpful to have a thread that compares kernels.
Each post being a short comparison of at least 2 kernels should be sufficient. Performance, battery life, conditions (e.g. ROM, heavy user? non-gamer? etc. ) and special features (that set it apart)of a kernel would be good ways to compare them. Perhaps a quick rundown of your current kernel and why it suits your needs best could be good as well.
This is not a thread to tell me what you think the best kernel is. I believe that all custom kernels have their merit being somewhere on the balance between battery life and performance + a few features and suiting different people based on their needs.

Gonna reply to this thread I made a while ago after a bit of testing. I think it would be a good starting point for anyone who is indecisive with kernels.
Today I thought I'd compare 2 kernels that I've been using a fair bit recently. Both are based on S7 edge firmware, but have counterparts for S8 ROMs. The disclaimer is that I didn't have time to try every version of the kernels, nor will I promise that my experience will be the same as yours.

They both sound pretty good, but it's the real life performance that matters right?
Versions used
I've used super stock 2.7.1 and 2.9 (the versions that came with superman ROM 2.6 and 2.7 respectively). 2.9 will be the one discussed today. I have found the performance quite similar between the 2 versions however.
I've used Notorious 1.9.1
Kernel Mods (that I used)
Both were kept very close to how the developers intended
I changed the to IO scheduler on Superstock to Zen
And I changed the internal IO scheduler on Notorious to Row, external to maple
Both I used Westwood TCP congestion control.
Both I kept with the stock governor (interactive)
no undervolt for notorious kernel
Conditions - my ROM and usage pattern
Superman ROM 2.7 with Magisk root
Debloated
Black theme, wallpaper and ui etc.
clock widget xperia running
Force doze with significant motion detector disabled
Greenify privileged mode (pretty much all social messaging apps greenified)
Magisk module to doze google play services
I turned off pretty much all the advanced features: smart alert, smart stay, don't turn on when dark etc.
Auto brightness on.
BT always on (connecting to car and smartwatch)
Location always on
4g, volte and viLTE on
WiFi off (I got plenty of data)
Charged to ~75% at night every day
Use was moderate. Involved BT audio on 15 minute drive to and from work. Variable tasks being done on phone: calls, texting, messaging (whatsapp, messenger lite), looking up internet, occasional remote desktop. 8-9hr day at work. Some messaging, calls, texting at home but less than at work.
No games on phone - I have a busy job and I have a PC, PS4 and WiiU.
Performance
Superstock has very good performance. Absolutely no lags. UI feels smooth and fluid. I don't game however.
Notorious feels smooth and snappy despite being quite underclocked. Developer sped up the boot animation fps. Maybe it's in my head (and therefore insignificant if any), but possibly a bit slower to start apps. No lags however. Again, I don't game on the phone.
Battery
Superstock
Very good battery. A fair bit better than stock. I could lose between 1-4% overnight (6-9hr sleep). Never bothered measuring SOT but the phone lost on average ~20-25% per day moderate use as outlined above.
Notorious
Excellent battery. On my off days, I found that notorious enters deep sleep faster than superstock leading to less idle drain. It also seems to drain battery slower when screen on. Would lose 1-3% over a 6-9hr sleep. Average day would use up about 12-17% battery moderate use as outlined above.
Special features
Superstock is a plain kernel that just works out of the box. Not many modding opportunities - can adjust clock speed within the stock range. No voltage change. Can use the 3 basic governors. conservative, interactive (stock), on demand. Can change IO scheduler and TCP congestion algorithm. Only notable feature is the safety net green. A few services disabled according to the developer, but that is about it.
Notorious is very customisable with mtweaks many governors to choose from (I only bother using interactive). Under/overvolt and under/overclock avaliable for CPUs. Under/overvolt and under/overclock available for GPU. Boeffla kernel wake lock blockers. IO scheduler change, TCP algorithm change. I changed very few settings, but it is also commonly undervolted. On the thread, people liked to use bluactive, impulse and relaxed governors rather than interactive. With Notorious, I found that undervolting didnt really increase battery life much and gave me the increased paranoia of silent corruption/ instability. I change the TCP and IO so that it theoretically optimises my user experience. Realistically, I found no difference compared to stock and it was more for my obssesive compulsive side.
Verdict
For a non-gamer like me who uses the phone for calling, messaging, internet, video, music notorious provides more than adequate performance with greater battery savings than superstock.
Superstock I'd imagine to have much greater performance under a big load. It was subjectively more responsive and faster when doing my low power tasks.
At the end if the day both were much better than stock for me in terms of battery. I'd say that Superstock would be more for performance and Notorious would be more for battery saving. Any questions or comments, ask away!

Hello,
Thank you for the very detailed review. :good:
May I ask how did you flash the notorius kernel ?
Did you installed the Superman ROM and then reflash the kernel over it ?
Thank you. :fingers-crossed:

Glad I'ts helping someone choose, cos I was very on and off abuot which one i wanted until i actually did the tests.
This is not the right forum to post this lol. This is meant to be about kernel reviews. The notorious kernel forum itself however isnt very clear.
It's just simply installing via twrp. dont forget to clear davlik/art cache after installation. Also, you need to flash root afterwards. I recommend you dont flash the root that the kernel comes with and to flash the root separately as there have been some bugs regarding that and also so that you can get the most up to date root.

Generally speaking this depends on the performance you need. If you can get your games to run sufficiently fast underclocked like on notorious, it will improve your battery life more just like it does in general. If it's too slow that way you'll have to see if super helps over stock. You could also try notorious and up the clock to more stock values but test out undervolting on it (as mentioned that does pose some risk) and see if your particular chip can be stable at a nice undervolt. Undervolting at high clocks can potentially save you a lot of battery life, but it depends on whether your chip is a "good" one or not.

Yep agreed => try games out on notorious. if they can work well on low clock speed, then keep it. Trying speeds between stock and notorious can work if the games are too laggy. Stock values may be necessary depending on what games you are using.
Undervolt may also help to improve performance while at lower clock speeds a less heat generated. Less voltage does also theoretically mean less power used. I have found the difference in battery life and heat with underclock to be quite insignificant. People calculate it to be 2-5% less power used. Given notorious already uses less than 1% per hour on average use for me. It means i'll be saving at best 5% of 1% so 0.02% per hour. Not much power saved and not worth in my opinion given the side effects.

The key is to undervolt during gaming, not idle. Undervolt can give exponentially more power savings at high clock speed. I agree it's not going to help for low clock speed and isn't usually worth the risk to corruption. With my Nokia N900 (back when you actually had to milk out all the MHz you could just to get 3D games on a phone, or in my case MAMEing arcades i could greatly increase gaming time when i dropped the volts for the highest CPU frequencies.
I appreciate your careful review of the two kernels. I'm still trying to figure out the ROM jungle for my new S7 Edge. Are these kernel and ROMs you are talking about snapdragon compatible or it this thread purely in exynos territory?

Agreed that the ~5% savings would translate to a greater amount of power saved during gaming in theory. I dont personally game on my phone, so your experience on this is better than mine haha.
I have the G935F. As far as I understand these kernels are for Exynos only. Good luck if you are searching for a good development scene with the snapdragon version. There are a few ROMs and Kernels i think. I have no idea about quality.
