Does anyone know what the difference between the various CPU governors and I/O schedules are? The recommendations I see vary a bit, but there's never any explanation, beyond "this is what I use, seems good". Thanks!

For Motorolas, you have to add MotoHotPlug and/or HotPlug governors, which seem to be similar to Interactive, albeit even more aggressive rampup of speed.
For grins, I'll run 3D mark / ice storm (regular) with the various Governors. Here's the results thus far:
CM10.1.2
Hotplug: 1926
Interactive: 1721
OnDemand: 1711
When I have time I'll run it in Icarus / stock and see if it makes a difference.
After getting a little annoyed at the runty, poorly mapped-out, scratchy thicket of real and imagined performance tweaks, I decided to embark on a semi-long term project to determine what's real and what's "zomg mega-booster performance pills".
First project was to evaluate existing performance options on stock CM10 for actual gains using experimental design. (tl;dr: for those geeky enough to want to know, it was a main effects only d-optimal design with 32 design points for the 16 parameters listed, including several lack-of-fit and pure-error replicates. I could go on, but do you really want me to?). I ended up with a list of 16 parameters all together, from the Developer Options and Performance settings, based on their showing up in various performance tweaks discussions.
The main challenge was finding a way to measure actual performance instead of perception. I settled on several benchmarking tools: Antutu, Quadrant, SQL Benchmark, and Chainfire's benchmarking app. One of the parameters being tested ("don't keep activities") actually breaks Antutu at the graphics testing step, so I'm not reporting anything from Antutu.
All told, out of the 16 parameters tested, only 9 showed any kind of effect whatsoever, and combining best settings for all 9 simultaneously, total performance only boosted by ~20%, of which fully half was due to switching max speed from 1000 to 1100. this means the other 8 settings combined for a total boost of ~10%, meaning individually they're peanuts. The remaining 7 settings that showed no effect are only so much fluff and unlikely to do a thing for you performance-wise.
Results are summarized below for your reading/teeth-gnashing pleasure:
Max Speed (1000 versus 1100): Very clear, notable difference between the two settings on all benchmarks. This is the expected result, about 10% improvement in all benchmarks on average. Recommendation: set max speed at 1100.
Governor (convservative vs interactive vs ondemand): This only had any impact on Quadrant benchmark, no other benchmarks appeared to care. In Quadrant, conservative was the worst overall, while interactive provided an ~ 5% boost and ondemand gave ~6% boost. Recommendation: use ondemand.
Scheduler (BFQ, CFQ, noop, deadline): I don't know what schedulers do or the differences between these settings, but the only place they had any effect at all was in the SQL benchmark. There were clear differences here though: BFQ was by far the worst. CFQ and deadline were about the same with a 17% increase in SQL activity performance. noop was the best with ~ 20% increase in SQL activity performance. Recommendation: use noop. [update: some have reported stability issues with noop. If thus us the case for you, CFQ would be the next best choice]
Zram (disabled, 18% default, 26%): Zram effects only showed up in Chainfire's benchmark app, specifically for Java activities. Default 18% setting performed worst but disabled setting wasn't significantly different. 26% setting gave a 4% boost, but again, only for the java-specific benchmark. Recommmendation: use 26% setting.
16-bit transparency (off or on): Turning on the 16-bit transparency setting gave a smallish 3% boost to Chainfire's java benchmark. It did not have a measureable effect anywhere else, and I did not visually see any differences anywhere during testing. Recommendation: turn on 16-bit transparency.
Kernel same-page merge (off or on): This had a *negative* effect when turned on, resulting in a 1% performance hit on Chainfire's native benchmark. It did not have any measurable effect anywhere else. Recommendation: Keep off.
Don't keep activities (off or on): This was very problematic: it provided a distinct improvement in quadrant score (+8%) when turned on, but behaved poorly with other apps (Antutu being one). Since it didn't seem to help anywhere else outside of Quadrant and didnt' play well with others, recommendation is to keep off:
The following list are the settings that had no measureable impact anywhere. Any attempt to claim they have "zomg" status should be summarily whipped with placebo pills, or else they should let me know the exact details in which they supposedly work and I can test.
Placebo hall of shame:
Surface improvement (since it had no effect anywhere, why not just set it on banding/blur and have the best pictures?)
Background process limit
Disable HW overlays
Force GPU setting
Any of the animation scale settings (although they look snappier at lower settings, so it at least *feels* faster)
minimum speed (seriously? people think this has an effect? keep at 300 for best battery life)
Allow purging of assets
Hope you like this, y'all! Let me know if there's any other mad-scientist experiments you'd like to see.
Nicely done. How many times did you run each test? Or perhaps the results were very consistent.
FYI; regarding the governor, scheduler and the like, you may want to have a look at this thread;

I think gives your tests / results some perspective as well.

Thanks for the link. Very informative.
How familiar are you with factorial designs? All parameters were tested simultaneously in such a way that their individual effects can be partitioned out mathematically. That's what allows me to test all those settings with just 32 runs and still get solid estimates of their effects, and more importantly, the amount of variation around them (a requirement for distinguishing real effects from noise).
I suggest googling "factorial design of experiments" if you're interested.

Re: [CM10] NC Performance (and) Placebos
Good suggestions. Before trying these third party tweaks would be good to know a few things from actual users:
Has anyone tried any combinations of these tweaks simultaneously? If yes, did they all play well together? If no, details please!
Some of these appear to have device specific settings, can anyone share settings being used on the NC?
I intend to sandbox these, as i have little desire to use then in real life just yet. Can anyone confirm that if i restore my current setup, the restore process will clean out whatever settings these tweaks out in place?
Speaking for all scientists, thank you kindly!

Have only used V6, from my experiences, restoring a Nandroid or flashing a new nightly will clean out everything it changes other than the files you store on the SDcard. This post details how I set it up http://forum.xda-developers.com/showpost.php?p=34991382&postcount=1234
I never really noticed a huge performance boost from V6, it did reduce the lag that was in the Beta's and early nightlies, mostly seemed to keep memory available and avoid the lag issued in the early builds. Have not used for the last few weeks since performance has improved on the newer builds.

Thank you!
Thank you for your measured and logical approach and recommendations! It is appreciated. I have experimented a little with the third party tweaks and haven't found any that fascinating, honestly.
When I install CM10.1, I also flash a script I made to customize to my preference and delete stuff I don't use like language modules, ringtones, quicksearch, boot animation, etc to free up some RAM. Between that and killing memory hungry apps when I'm done, my old Nook is still holding on reasonably well.

Got to tell you, your suggestions on settings are paying off. My nook is smooooooth. Is working ok there is sometime that lag liittle bit, but my p3113 also doing the same. I will stay with this 0120 nightly for a while with your settings on perfomance. .

I'm surprised that zram enabled IMPROVED things. So between disabled, 18%, and 26% (no idea what default really is without digging in the code), 26% was the best option?
Interesting. I thought zram would improve multitasking (maintaining background activities) at the expense of potential slowdowns (compressed swap to ramdisk).

It might have that effect, but wasn't apparent in the benchmarks i used. It could be that a different benchmark is needed to detect it, or it could be the negative effects are too small to be measurable compared to the normal "noise" of operation.
Any ideas how we could measure this more explicitly, if there is any interest?

Good question, I'd think it'd require some way to switch activities around and somehow measure their switch rates, but the environment would be quite difficult to keep consistent.
BTW thanks for the scientific work on this stuff, MUCH better than "OMG THIS TURNED MY TABLET INTO A UNICORN" posts we see a lot on tech forums.

Since it would help most when memory is low (like it ever isn't), running two memory hogs simultaneously should show an effect if there is one. A custom memory-hog app built under two different names, perhaps?
I have a shell script that creates a swapfile and enables its use that would also be well tested this way, since zram creates an in-memory swapfile. I was never able to see any tangible results except for the output of "free", so I don't use it anymore, and haven't tried it under CM10.1.

I am using the latest Arrrghhhs anykernel along with ROM toolbox pro to underclock my min clock speed to 96MHz and overclock my max clock speed to 1890MHz. Im using ondemand as my cpu governor and row as my i/o scheduler. I have the option to overvolt and undervolt using ROM toolbox as well. I did some searching but cannot find any info specific to the Atrix HD. I was just curious if anyone has tinkered with this much and if so what have you found to be the best clock speeds/governor/scheduler/voltage combination. I've never really heard anything about overvolting, what if any benefits can come from this? Also what is the most you have been able to undervolt with causing a bootloop or other issues? On my old S3 I had a app that would test if your settings were stable by running different processes to put a heavy load on the device. You could run it as long as you wanted but I had learned if it reported no errors after 10 mins it was usually pretty stable at those settings. I cannot remember the name of the program and searching turned up nothing, I was hoping someone knew of it or knew of one that does the same thing. Thanks in advance for any help!
Guys.. With every Android since the 2.x, you could activate the "Developers Options" and activate an option called "Show CPU usage".
"The numbers show the average load of the CPU in different time intervals. From left to right: last minute/last five minutes/last fifteen minutes"
My doubt: When I install any CM13 ROM (now I'm with Exodus) on my S5 (G900M), the load, after some minutes, are always near 10. Now I'm staring at it, with many apps installed (whatsapp, facebook, uber, maps, messenger, firefox, mx player, es file explorer, foursquare, traceroute, wifi analyzer, gmail, imo, os monitor, tinder, fing, poweramp, mindroid, remote desktop, 99, youtube, andsmb, diskusage, soundhound, photos, dropbox, goseek, instagram, juicessh, google now, picsplay, speedtest, skype, swiftkey, stabilitytest... just to name some...) and it's 11.32 / 14.37 / 23.11
Now the problem: whenever I install Boeffla Kernel or CrazyKernel, the load is ALWAYS higher.. always nearing 20. With default options, or trying to tweak the cpu options in both kernels.. and the bigger problem is that I SENSE that. The phone seems to RUNS SLOWER.
ps: If you LOCK your device (or let it lock by the timeout), this "load" value will raise because the cpu will also run slower.. it doesn't mean it's working more, just that more work is queued to the cpu, as it doesn't NEED to work on it (because it's locked/screen turned off, etc)
Hi,
I guess everyone will have that. So the poll is quite useless.
The reason for it, as I tracked down:
Two governors (intellimm and slim) are adding overhead to the system, even when they are not used.
Why? I do not know, as I am not the developer of these governors.
But for a test, I removed them from beta11 and compiled it as a beta11test1 version, attached here.
Let me know if removal of these governors lowers the cpu utilization for you down to stock levels almost.

Wow that was fast. I'm testing right now and yes, the CPU load is *finally* down to ~11 like it were with vanilla CM13 kernel (which I think is what Exodus uses).
Still I get a little lag here and there mostly when "loading" stuff (like when clicking in a group chat on whatsapp, which needs to open a huge .db to display the history.. I think).....
But nice work.. I wonder what more could be optimized.. it's strange to a vanilla kernel be snappier than a custom .. given the experience you have..
Thanks

I am not sure vanilla stock kernel is more snappy. I feel it is the other way round personally. But this is about expectations and perception. Also it is about what is important for one. A custom kernel gives you many other goodies that might of course compromise in other areas. Nothing is for free.
And I personally prefer some other features over pure performance.
But well, that's it. I will not do more, having in mind the s5 kernel is only my #5 kernel in terms of priority. Sorry.

Hi everyone, this is a guide based on my personal tests, which I have the pleasure to share with the whole community, for experienced users and not. Regardless of whether you prefer to use a MIUI stock or a custom ROMs, these are a series of tricks, Tweaks, passages, let's call them what we want, to get the maximum in terms of battery life, without sacrificing performance. First of all, we talk mainly to have the better experience for MIUI and PRINCIPALLY for ROOTED users, and custom ROMs too. No rooted users cannot expect miracles because there are modifications that mainly affect the entire operating system. I also hoped to find the Holy Grail, but unfortunately it still hasn't happened.
Anyway,: If you want to use a MIUI (preferably GLOBAL, I will explain later why this is the case); the first thing I recommend in addition to a backup (just in case), it's a pretty safe Debloat using the complete Saki tool:
https://saki-eu.github.io/XiaomiADBFastbootTools/
After giving our device a nice cleanup from Bloatware (obviously you choose which ones to remove or not, personally I removed almost all of them leaving only Gallery, Phone and Messages without any problem), the best part comes, and that is to apply all the settings for a better user experience in every aspect. The MIUI is obviously not optimized as a custom ROM, so we should do it ourselves. Personally I am a root user, so first of all I flashed Evira Kernel and Magisk (with which I am wonderfully) and put modules that I personally recommend: LKT (or others similar modules), Syconfig Patcher (they are the ones that interest us), but of course the appearance rooting is optional.
But back to optimization; for each application that we will install, we will have to configure its type of activity in the background based on how much you want the app to act in the background. For example, the "MIUI Calculator" app, which I almost never use, will have set "limit app functions", otherwise applications that we will use more often will suffice "MIUI optimization", such as "Youtube", and what more important, for apps for which notification is essential (such as Whatsapp or Gmail), remove the limitations.
But it's not over. Write in the settings menu "change system settings", then a list will open with all the apps we have installed. Clicking on one of them, a menu will open, where clicking on "battery and performance", we will choose whether to put the limitations in the background or not, same speech as before, limit everything that is not necessary, inverse speech obviously goes for app important to us (gmail whats etc), which we will leave free to act in the background.
Still in the "battery and performance" menu, click on "battery optimization" and optimize everything you can, except as usual, the apps you don't want to be limited as in the previous two steps.
Now we can activate the "Battery saving" mode, which will obviously work on the whole system, except for all the apps that we have NOT optimized before. They will absolutely not be touched. (A nice break of *** optimize the MIUI , Doh!)
Remember that at the beginning of the guide I told you "better to focus on the global rather than the ROM developer?" well, using a third-party tool like Kernel auditor (personally I use EX Kernel Manager with which I am wonderfully), in the dashboard the developer rom had higher CPU peaks than the Global.Il that involved higher consumption. And it is a tool like this "Ex Kernel Manager etc" that we will now configure.
Step 1 Configure the Governor.
The mode and the speed with which the processor passes from the maximum frequency to the minimum one is regulated by the so-called * "Governor"
There are more than 100 different types of Governor for kernel, more or less different; but not all Governors are present in the Kernels. In case you are using Evira Kernel, my advice is to set the CPU to the "Alucardsched" Governor which offers an excellent compromise between performance and battery life.
EDIT: Recently tested zzmove gov with Evira Kernel: little performance is lost compared to alucardsched, but the battery benefits. Personally i have chosen profile 3 (ybatex).
Step 2 I / O scheduler
It is precisely a program in the form of an algorithm which, given a set of requests for access to a resource, establishes a temporal order for the execution of such requests, privileging those that respect certain parameters, so as to optimize the access to this resource and thus allow the completion of the desired service / instruction or process. In this case, I recommend setting it to noop or Zen, for an approach closer to the battery.
In the GPU section, if you don't use particularly heavy games, (personally I play every now and then in clash royale and I don't have any kind of lag at all) you can also set up your own governor here, setting one like Powersave, but in any case this is completely subjective .
Once everything is set up, all that remains is to talk about the last aspect,
the Doze.
Originally introduced with Android Marshmallow, it allows applications and various activities in the background to "sleep" when the device is screen off. Of course over time it has been increasingly perfect, which is why: In a Stock MIUI you can afford to download Naptime, Servicely or Greenify if you want (personally I use Nap & Serv) to enhance Doze or hibernation as in the case of Greenify (excluding as always the apps we want to be in the whitelist).
IMPORTANT: different words must be made for Custom ROMs, which being already optimized, and having a definitely more effective Doze than the basic stock, DO NOT NEED third-party apps like Naptime or Greenify. In this case, even setting everything as the guide, notifications will not arrive when the screen is off, except when you unlock the device.
so as far as custom ROMs are concerned, you just need to limit the apps as in the guide, leave in the background those you don't want to be touched, and always remove the optimization for these "important" apps, I always repeat "whatsapp gmail etc". In this way you will be able to activate energy saving quietly, the apps you prefer will not be touched, and you already have a Doze optimized like the rest of the system. The only thing that applies to Custom ROMs, is always to set the Governors as described above.
That's all at last :fingers-crossed:.
Attached here are my screenshots, with 8 hours of SOT, DIVIDED IN THREE DAYS, so sometimes the phone was idle as during the night or at work. With these configurations, in a single day, or in a day and a half, you will easily arrive even at 10 hours of SOT and maybe even beyond. I hope you fell asleep while reading, but I wanted to make a guide (even if long), to explain to those who may not be very practical, some things that can always be useful. A simple "thanks" is always welcome!
Greetings .:good:
Two more things: for more battery saving, u can disable automatic sync in settings menu (so sync when u want), and probably after some rebooting, it is possible that the governors will reset itself to the default one. So I suggest you check it out.
Really thanks for your concern about battery life stuff, and yup indeed on custom ROMs sometimes we can get up to 10hrs SoT without any mod or even a custom kernel (my experience)!
I'm looking forward to see how long the battery will last when we get Android Q update from MI..

Thank you very much! If I am not mistaken, beyond the various new functions, the "Extreme battery savings" will return. With an adequate optimization, as above (also to be as clear as possible with any type of user), we hope to see many beautiful new performances :fingers-crossed::fingers-crossed:

Thanks for the guide, with it you cleared some doubts that I had, I just have a question, for battery/performace Anxiety can be better than Zen? For what I read the past days is an optimized version of Maple wich gives good balance between battery and performance.

Thanks bro; Zen and Anxiety are so similar as they are also different. Each I/O scheduler we choose can be the most indicated according to what we do with our device. Let me clarify: Anxiety is better in term of battery saving comparing with Maple, "It prioritizes reads over writes but tends to starve writes more".
Zen is based on noop and deadline, very stable and have a great balance, for this reason i choose it. But as mentioned there are no schedulers better than others. But better according to our needs. My advice is to try them both, and see how you are in your daily use of the device :fingers-crossed::fingers-crossed:

Battery life is not the only thing I look for. Stock rom batter life is good enough after debloat in many crapps using saki. Stability, functionalities, security.. overall stock rom is the way to go for me at the moment. Did you mention restricting permission on apps?
Welp, after playing Free Fire for 1:20:00 and PUBG for 4:00:00, a little Browsing, my battery usage was of 76%, I don't use LKT because last time I try it my wifi started working weird, only use Snaptime. Evira 2.2.
:good:
I would like to know what do you think about zzmove governor that was added in Evira 2.3. Thanks.
I tried to use your settings but at reboot all configuration change to interactive or schedutil for CPU, msm-adreno-tz for GPU e anxiety for Scheduler I/O. I guess there are some conflicts with LTK.... I don't kwow how you have 8 hours of screen on your device...

Mate, if u read with more attention, i wrote about it in my second post..
Just reconfig Governor already. It could be happen, is normal
Im going to test darknesssched with zen without sysconfig patcher (Had mobile data connection issues), alucardsched give me a little lag in PUBG, when I use darknesssched that dont happen, zzmoove dont convince me, it is based in conservative and hasnt been updated since 2015, for what I know cpu governors schedutil based are more "smart".

Yep
Hm, i am locked...and have no kernels installed. And I'm not planing to do it.
Did restrictions and debloat and this is what I get.
Since I am on 10.3.5. my battery is weaker..
On 10.2.7 I had 2 sims with lousy signal, and I was having about 7,8 h of sot and same use.
Now before this tweaks I was hardly getting 5h in 24h
Yesterday I had weaker use then ussual but still, this isn't very good..but I think it is better.
I dont like this 10.3.5.
