Hello all!
Just upgraded my wife from the MyTouch 3G Slide to the G2 as she has to have a keyboard and we were on our 5th replacement Slide. So, as she is not the geek that I am, she will not be constantly flashing new ROMs and such. However, I am going to at least install the latest CM and I am looking for kernel suggestions. I already have root, s-off, new hboot, and all that, I'm just waiting for CM7 to finish downloading.
I started using Android with the G1 and constantly updating Radios, as well as ROMs and I currently use a Samsung Vibrant running a TeamWhiskey ROM. It's stable as anything, I like the theme, and CM7 still has some broken stuff on the Vibrant. I'm glad to see that Eugene recently picked up a G2 as he made some bad ass kernels and ROMs for the Vibrant.
So, let's here those kernel recommendations and why you recommend them.
Thanks!
Well am currently using mexdroidmod and their kernel is pretty awesome because its fast and stable. My best advice is to test the diffrent kernel and read through the tread, see what people say about it. All the kernels I have tried are all awesome so you should try them

pershoot's kernel. great batt life and OCing
Umaro's kernel has been rock solid for me and has tons of features as well. You can OC all the way to 1.9 Ghz if you so please and it has smartass.
well considering your wife isn't much of a techie.. i say you should go with pershoots kernel because he's always releasing updates and i've never had a problem with any of them. the battery life is excellent if you use the right radio (.17 and .30 have been good to me), but you need to experiment with this though. the phone runs beautifully, just make sure you use superwipe+ to format/wipe so you don't end up with gps issues like many people have had, good luck!
I've run umaro, eugene, pershoot, flippy, pyro, etc etc... aaand I've decided that the provided kernel is pretty much good to go. yeah, there are some little trinkety things with a few of the above kernels that the standard CM7 kernel doesn't support... but honestly, they're worthless to a user who just wants to turn the phone on and have it work.
set her up with the stock kernel @ 245-1017 (I haven't found a reason yet to ditch the ondemand governor, it seems to work best with CM7) and a vanilla gingerbread launcher and she'll be blown away.. that's my $.02
Like said above, CM kernel is great. I've tried most or even all available kernels for CM and finaly decided to stick with original one. It's stable and supports OC (up to 1.5GHz) "out of box", so really, I see no single reason to use the other ones.

I'm also thinking about changing the kernal, but only for smartass. Does smartass offer that much of an increase on battery life or anything else? Also, when you OC, do you use SetCPU or just CyanogenMod Settings?

not at all pooping on any of the guys who swear by smartass/other governors, but the change in battery life is almost unnoticable for me.. the change in performance however can be pretty apparent.
here's my problem with "battery saving" governors:
in order to save battery, these governors are supposed to be more intelligent about which frequencies they select once a task is called... well, that's all well and dandy, but the problem is that the majority of battery-hogging apps (ie streaming music/video, gaming, browsing for a long time, being on the phone, etc) are still going to be battery hogs with or without a fancy governor. the governor isn't capable of making an app that needs a lot of processing power run well at a lower frequency, it can only try to be more selective about which frequencies it uses in order to attempt to save battery life.
additionally, most people use their phones like this: phone is idle (ie screen off), and a call arrives. call ends, phone is back to idle. texting a few people, back to idle. playing a game for 15 minutes, back to idle.
is it really logical to assume that these short bursts of activity are going to benefit at all from a fancy shmancy governor? I doubt it.
I still swear by ondemand or interactive (both work well for me) thru built-in settings if possible (ie cyanogen performance settings). second choice would be setcpu with no profiles (unless you're overclocking heavily, then you should at least have a temp warning profile). at this point, screen-off profiles don't do a damn bit of good, because pretty much every kernel we have for the vision is going to scale down during inactivity.

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,

which kernel out there is the best right now? in battery life and speed
theres only one that fits best battery and fastest.. trinity kernel.
I like Trinity but Motley also did very well for me.

speed..
Ill say motley. I tried trinity kernel. Its good. But I getbetter performance,stability, and battery life with motley. All these battery screen shots really mean nothing. Why? Because none show real heavy use. I can easily get the same stats or better with light to moderate use. Show me some stats showing 8-10+ hrs of screen on time. With some heavy app or game usge. Anyone can use device for a few hours. Then leave it in deep sleep and show the same or better stats.
I've tried all the kernels out so far. They are all good. Its a matter of personal preference of features you want. Some pack things others don't. MOTLEY 'S ATM is the only linaro based kernel. So its using new additions/components. Better optimized. Benchmarks are cool but its real world performance that matters most.
I'm running stock rom with motley latest linaro based kernel with Zram, then CPU overclock @ 1.624ghz and gpu overclock @ 520mhz. I'm also undervolted -75mV across the board. So my temps stay low. Which equates to my device running at a higher performance speed longer.
The best thing about stock rom is I can measly flash different kernels and not have to worry about flashing a rom and setting my apps n all THST all over again. I can flash a kernel with no wipes and be good. Plus stock rom is the most stable ATM. Can't lie though, I am anxious to flash some roms. THST paranoid Android one looks really good. Along with the pure linaro based rom. That's the great thing about choices.
Its not a matter of who has the best kernel. Its more about what you looking for in features and personalizing your device to cater to our needs.
Asking who has the best kernel is like asking who is the best developer on xda. I don't think that's fair to the developers as they ALL work hard on roms or kernels. Forget the popularity contests.
THEY ALL THE BEST lol. Some are just more seasoned than others. Which is OK. I love the fact we have variety of things to choose from. I've been impressed with trinity kernel, based on scores I've been seeing. But I'm also impressed with faux kernel and its a more straight forward one with lots of new Linux commits and additions. All the kernels have a personality of their own. I love the fact that twrp makes it very easy n simple to try out any kernel I want for nexus7. No matter who makes it. Every developer has its followers. You also have people who like to try out different setups.
Choice is a good thing! That's what I love about Android.
I've got to say for me trinity is the best kernel for the Nexus 7, updated daily and great communication with the dev makes this an awesome kernel. The trinity toolbox app is the icing on the cake.

1. trinity kernel has been using linaro since april of 2011, on the nexus s, the gnex, and now the nexus 7.
2. zram is a placibo. theres nothing there
3. stock rom is good, but i prefer a pure aosp build. no, they are not the same.
4. and the last two paragraphs are the absolute truth.
5. really, you should try them all, let your device tell you which kernel it likes the best

Thing with zram is, its not for getting higher benchmark scores or immediate performance. Its more so for heavy multitasking. Is been proven to help. The placebo is on people who think its supposed to provide some immediate result. If someone is a heavy multitasker on their device, then zram would benefit them. If you not much of a multitasker, then zram will show no Bendix for you.
You are right though, about trying out different kernels and such. Pure aosp rom sounds good. I just hate having to reset up my apps n stuff. I know titanium good for that but me personally, I'm waiting for roms to mature more and have most things, of not everything working. All roms so far seem to have something not working yet. Which is fine. Nature of the beast.
I think I might give trinity kernel another try. I did buy the tkt app. But never used it in conjunction with the kernel. I bought it just for the automatic script it runs..lol plus to show support. I heard tkt app works best with trinity kernel plus allows you to tweak features only in trinity kernel.
Ill download the latest build Trinity has and see what's up. Performance and better battery life is always a good thing. Its gpu is overclocked to 520mhz also?
Trinity HANDS DOWN its been 3 hours on sleep and ITS still at 100%! + the ridiculous speed along with the power saving features. I may be new to the Nexus 7 scene but this is hands down to godly .

Thing with zram is, its not for getting higher benchmark scores or immediate performance. Its more so for heavy multitasking. Is been proven to help. The placebo is on people who think its supposed to provide some immediate result. If someone is a heavy multitasker on their device, then zram would benefit them.

im not sure if gpus oc...but when u underclock..theres absolutely no performance difference..and saves battery too! 102mhz-1100mhz on demand/deadline..god like battery life. 4 hours screen time...still 45% left...shouldve been more if i didnt flash roms in between battery life. also under clocked, gta 3 and cs portable runs great and smooth still.
thanks to simms, I tried out trinity again. I flashed the latest builds. ran some benchmarks. for some reason, my device doesn't like the highest speed on benchmarks. it kept rebooting during them. so I stayed at 1.5ghz. governor I used was performance and on demand. for scheduler I ran with deadline. i forced cpu online and put fysnc on faster, thanks to TKT app. on quadrant, I was more concerned with seeing if I could achieve those crazy high I/O scores. which I did. my overall score was good but I've gotten higher on motley. it could be higher on this kernel if I get the 1.6ghz+ speed to stick. I was more impressed with my rl sqlite benchmark test. scored 18 seconds overall. which blows away the competition.
so I'm impressed with latest version of kernel. definitely better than the older build I ran of it from before. some things I've noticed though. where is the ability to undervolt at? no option in tkt app and the voltages tab disappeared from system tuner. also, this build gpu isn't overclocked. or might be better for me to say its definitely not running at 520mhz. I could tell this by the fps from quadrant. its running 59-60fps. on motley with 520mhz gpu I get 70-80+fps. just some things I noticed. not necessarily drawbacks. kernel runs very good. just got to figure how to make higher speed stick. since I can't seem to adjust voltages on this build, I can't increase voltage or undervolt it. if this can be done on trinity kernel, let me know how. its not showing voltages in tkt app or system tuner.
overall very good kernel. will run it for a while to see how battery life is. I will likely underclock it like above poster mentioned for best battery life. I noticed nexus 7 still runs great underclocked. no lag.,no matter what kernel I'm using.
I've attached screenshots of my benches on latest trinity overclocked @ 1.5ghz. I know my device can take 1.6ghz cuz on motley I can run the speed fine, even through benches. so have to see why its not taking on trinity kernel. maybe voltage needs to be increased.
so it doesnt matter if trinity is still in experimental? its that good? i guess ill try that one out

there are more features that are going to be added, theyre being added all the time. ask gnex owners how the options grew(same app btw, different devices running trinity see different features in the app. so you purchase it once, and use it on multi devices. btw, voltage adjustment will be added, remember how new development is on the n7. also, if other developers added the options into their kernels, theyed be able to use those features with their kernels

thats just trinitys method of rotating the kernels.. starts off in experimental(every kernel is tested to boot and run before it every appears here), then it graduates to prerelease if it makes the cut, and then if you guys like it it makes its way to release. its just that trinity development is so new here that there isnt a prerelease yet

I've underclocked mines to 1.1ghz also. battery doesn't want to budge from 100% so far..lol. it's barley sipping battery. the UI and browser is fluid n smooth at this underclock. which is a good thing. the real test will come once I play nova3 shortly. if it plays lag free on this lower speed then underclocking is a winner. I set my governor to interactive though. you get better battery life than ondemand. using deadline also. with fsync set to faster.

I understand nexus 7 is still infancy, developement wise. its cool. just wondering if those features were included since the option disappeared. I could undervolt or increase voltage on motley kernel. the tkt app would let me do it on THST kernel as the section shows for it. but I like using system tuner for undervolting when I was on motleys kernel. can't wait to see what new features get added. plus once I get my new phone, hopefully there'll be a trinity kernel out for it so I can use tkt app with it. the build is very good.

Interesting, 70-80fps, more than the panel.
You were interested in battery in an earlier post, this is me feeling meh and couching most of Sunday.
EDIT: Yes, emailing, tapatalk, browsing for laptop and not finding any, reading news in Pulse and flipboard, tweetcaster and testing slice(s?), gtalk, not heavy usage obviously. Screen wasn't on unless The Seven was used though.

Expect no less.
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.

one question... how to REALLY TEST and compare a kernel?
sometimes adding and modding the phone with custom rom, kernel, greenify and other manual modded cpu governor etc...... it's almost IMPOSSIBLE to understand if the perfornance, or battery life is affected by a kernel or something else.
A person could obtain a bad battery life but the culprit could be ANYTHING.....
so IMHO the easiest way to compare a kernel is the numbers of features and OPTIONS that allows it.... something like how many governor, i/o schedulers , tcp algorithms, dt2w..... and so on... because a PERFECT kernel... could be perfect in some roms.... and worse on others.....
there are too many complications about the number of apps, which apps, to use greenify or naptime/forcedoze , and a possible incompatibility with a specific ROM with specific kernel.
after all........ maybe the simpler test is to keep the same configuration of the rom for at least 1 week, make a nandroid twrp backup, flash 1 kernel, keep it 1 week ( and see results), then restore twrp with stock kernel/rom , then flash the second one kernel, keep 1 week, then restore backup, test 3rd kernel.... and so on? making it sure NOTHING CHANGE, no greenify change... no gaggressive doze setting change....
it would be nice if other people would write here they combination of precise KERNEL + ROM used to achieve a great battery life and SOT.......
No doubt all these kernels are well tuned and devs are making them better & better every day. I always use RADON KERNEL and it works with every rom just perfect, never tried AGNI though, two days back I flashed ElementX and Franco kernel but I noticed two big cores are either going "offline" or shutting them off permanently. @franciscofranco replied those two cores were thermal throttled or something (may be....) but after RADON I didn't noticed that issue, all 6cores are back online . So for now I'm sticking with radon I'll flash FrancoKernel next week and see if thingd sorted out..
Most off all I think we kenzo users are blessed to have all these big names in development thread.
Why isn´t Lineage Os on the List (a.k.a Cyanogen Mod)
I certainly like Radon best . Save battery and not lose performance .
I don't like AGNi . Because it update too frequently sometimes and little waste battery .And that ,I don't like the AGNi Controller ,One reason :For users who use other languages, this apk is difficult to translate . But , I can't deny it is a good kernel .
About Other kernel , I did not use them for a long time . So I do not understand.

Battery and performance are undeniably affected by your kernel.
For example, the battery life on Nitrogen OS kernel is amazing, and the reason for that is, reduced performance. It's not slow, it's smooth really, but it's slower than Radon's balanced configuration.
And I think your argument that a kernel can be judged by the number of features, governors and schedulers it includes is wrong, because you don't need multiple governors or schedulers to get a good experience.
At one time, you'll only be using one, and that's why the stock configuration of the kernel matters.
I think every custom kernel has their advantages and disadvantages.
All we need to do is tuning it.
For example, I use Franco kernel and I changed the input boost ms for better responsive.
Or I use nitrogen kernel and tuning the governor for better performance.
However, I choose latest ex kernel manager app to tuning the kernel. It's more friendly ui and more reliable.
And the best thing is latest version of radon/franco/exkernel/nitrogen/agni has unified fp support.
