This kernel has a considerable difference in i/o speed, I was scoring ~5600 with row & now I'm ~9400. both with fsync enabled. My question is how much was this part oc by, and approximately how much risk does this carry?
current setup
maxkern v4 rc2; cdromi 4.6.9; [email protected] these settings

It is a big jump from 5600 to 9400 in Quadrant. You are experiencing the I/O speed of FSync disable even though you had it enable during the Rom installation. I believed that Max's kernel has a feature which is called a "Dynamic FSync", hoped that is what he calls it. The FSync is disable during an active usage and enable when it is sleeping. To answer your questions, the CPU specification for the tf700t is 1.6GHz on all cores. For the risk, it is depend on how much heat is building up around your CPU. Most of the commercial components are rated around 85 degree Celsius. If it is exceeded the Absolute Temp Rating, it will fry. You can use a temp app to monitor your temperature on your average usages. I hoped that it helps. By looking at your score report, your temperature is at least around 50C or more because your CPU frequency is starting to drop lower than the actual setting. :fingers-crossed:
Thanks, I believe your right about fsync. Just opened trickster mod and disabled fsync to see what it would score in quadrant seeing how i/o is already peaking in the 9200+. My i/o speed with disabled fsync is ~5600 .... so off is on and on is off? That is not cool
Update
Reflashed with _thats kernel v4; i/o deadline; data2sd mod(64gb sandisc class 10); fsync enabled; [email protected] gov.preformance (for test)
~7000 i/o :good: quadrant score attached ~1400 increase w/ data2sd mod
disabled fsync and did second test i/o ~9700 so toggle works as expected
I've been enjoying cdromi w/ data2sd mod _thats kernel v2(&3 mod with cdromi updated), after testing maxkern v4rc2 for a couple days (runs nice) I flashed to _thats kernel v4 & new data2sd mod. My tablet was for lack of a better word ...****ty before unlocking and slapping on a custom rom. Thanks @sbdags & @_that for making my tablet smooth and enjoyable

Hey what are the best battery saving + good on performance settings for air kernel e. G governor and scheduler and btw I'm using slim ics 3.5 so is there any better kernel for battery saving.
P. S I'm running lion heart noop atm with 100/1200 and not too sure if it's killing batteries or not..

My suggestions:
use a lightweight, stockish kernel
---> slim ics is a fast, streamlined ROM and coupling it with a heavily modded kernel may only burden it with unnecessary overhead, so i recommend using stockish kernels like Franco's, _thalamus', or Pete's
play with the right governor-scheduler combo that works for you
---> if you're vent on using Air, you have to try out the different combinations that will work for you. Every phone is different and your phone has its quirks and strengths. When I used Air, I used a noop-lazy combo as this gives me the best battery life and performance when I need it, but this may not be true for you. So experiment and benchmark. This is what makes Android special: the power of choice and customizability.
Cheers!
go for the air kernel weekly 4.0
smartass v2 with noop scheduler and deep idle on .. works smooth and amazing battery life ..

What would you consider amazing battery life?
air 4.0 [Only Voodoo Colors (Original)]
with 400-1200mhz cpu freq ,deep idle on
smartassV2/ noop is not stable for my used.
have no reason, reboot random ...
try to ondemand dadeline
200-1000 cpu freq , deep idle off,
I think this is helpful

Your overclock isn't stable then.
It's a not a "per use" thing. It is just as stable as ondemand with deadline.
I had my best experience with
ondemand (lower the up threshold to ~85% via nstools, than it's smooth as butter)
200-1000 Deep Idle ON (ensure that deep idle works properly with TOP=OFF)
Deadline
I want to overclock my phone. I have doom kernel v14 installed. I installed no frill CPU on my phone. The min frequency I seleted was at 300 MHz (approx) and the max was 1.4 GHz (approx). Does this mean that the phone will automatically go between these values if I run a heavy app (eg GTA 3)? And what does the 'governor' and 'i/o schedular' mean and what does it do? My current settings are :
sio - I/o schedular
Performance - govenor
Min - 245
Max - 1.2 Ghz
Governor : Smartass v2
Mine is like this.
and what about the i/o scheduler? And what does govenor and i/o scheduler mean?
I'm also on Doomkernel v14 and my battery is draining so quicky. Its dropping 5% every 10minutes even when I'm using any light application. I have SetCPU and my sttings are Max 1401MHz and Min 134MHz with smartassV2 and deadline. Although speed is amazing but battery performance is terrible.

Performance governor is a "special" one in that it goes to the max. clock speed, and never uses the min., or any frequency in between. You can do that if you want to do benchmarking reliably, but I'm not sure it's good for battery life.
http://forum.xda-developers.com/showthread.php?t=1663809
^ That page explains all the governors, but from what I can tell from using Cool Tool onscreen system info app, "lagfree" on Doomkernel seems to be a higher performance governor like you'd expect from the name and not how he or she describes: it seems to scale down only quite slowly from a high clock, I'm guessing to eliminate any possible lag while scrolling the interface that might result if it scaled down quicker. And we don't have anything relating to multiple cores
Anyway, I think I saw you say you were on JokaWild as well. Looking at the Joka init.d scripts the SmartAssV2 parameters are tweaked towards performance and it comes as the default for the rom, so maybe try that as a more balanced option than Performance governor.
Another CPU governor and I/O scheduler mega-thread

I wondered as well if v14 was not as good as v13 3013 for battery life, but better for performance, but 5% in 10 minutes is a lot. Have you tried using the BetterBatteryStats app to find an explanation? Has it got better just through subsequent use / recharging?
Battery life really sucks on jokawild (actually in all CustomRoms).
I have mine like this (r800a):
-smartassv2/sio or bfq
-.62 stock rom with a couple of build.prop mods
-64 baseband
-juice defender
-brightness around 25%
-supercharger v6
My phone has been for like 4hr and still with 100%

Was it charging? That's impossible. I left my phone idle,lowest brightness and wifi off for about 30 minutes and it dropped to 96%.
I have deep sleep enabled,juice defender,

Well, it does depend some on the phone you are using as well as what kernel you are using. Kernels are complied from a variety of sources, with a plethora of options either baked in, or left out. Most kernels have features such as:
Speed tweaks
- Sysctl.conf / build.prop changes
- Overclocking
- Governors and I/O schedulers (How quickly the CPU scales to load, how the disk acts when reading)
- Ramdisk enhancements (Boot times, etc)
Battery enhancing tweaks
- Longer WiFi scan interval
- undervolting
- SBC
Features removed or added
- USB device support
- ext4 filesystem support
- color/contrast control
- App2SD
- Removal of debugging features
- HDMI out (if in place)
As far as Franco Vs Trinity, both remove the debug assets, but they differ in overclocking and that will be a huge deal in terms of battery life. The Trinity kernel overclocks both the CPU and GPU, at least on most of their kernels. This will give you more performance, but at a cost of battery life. The Franco kernel does not include undervolting either, which does save you power when the device is not being used, or not being used heavily.
I usually found that the Franco kernel gave me better battery life on my Evo 4G, but not every phone takes to a kernel the same way. Even if two of the same model of phone have the same kernel, one may work better than the other. You usually want to try a kernel for a day or two to let it settle in before you pass judgement on it.
Also, not kernel based per say, but one way to save battery in some situations and gain performance in others is to use a program like setcpu, or no frills cpu to make profiles that adjust the CPU governor and min/max clock speeds based on conditions.
Which CPU Governor is the best for battery/performance combo. Coz when I use hotplug with an overclocked kernel asphalt 7 lags, but if I use peformance as the governor everything is fine.
And also how do I add extra governors to my phone.
The best one is Hotplug.
Performance sets your CPU at the top frequency ALL THE TIME, maybe good for games, but a total waste of battery otherwise.
Extra governors: there are other in some custom kernels.
Just curious out there on what everybody is running their CPU frequency, governor, and such, Just looking to see all my options and how I can save battery and increase performance
You won't decide anything until you try. The freq and other settings are highly subjective. As per my usage, i can even survive on 1497Mhz and the phone would still feel buttery smooth, but i use 19xx Mhz step. GPU at 389Mhz. Using default SAOSP kernel with alucard governor + hotplug and the system is performing like a nexus device.
