Could you please tell me about each governor and best one for havs kernels is smarTASS OK
Sent from my HTC Desire using XDA App
There is no best setting, it's all personal. Some people want there phone to be real snappy and some like longer battery. Depending on what you like there is a best setting.
Read this, for the governors except interactive and smartass.
Since it seems you want to put in minimum effort from your side, smartass is fine.
between ondemand and interactive I personally think ondemand responds faster (although I thought it was the other way around). but it varies from a) application/usage and b)kernel so there's no "best" setting per se. I havent tried other settings yet...

Can somebody tell me what the difference between smartass and savagedzen cpu governor?? i cant get a solid answer searching the net!
Thanks guys for the help!
savagedzen is more smartass'ier than smartass. stick with interactive on the gb kernel though as it is reported to be better performance and battery life and my personal choice
So what you are saying is scratch out smartass and savagedzen setting and stick with interactive??
sent from the bathroom...
conservative is the best for me, i have tried savagedzen settings and they're not that bad. try out the settings, and maybe you'll see which one you'll like the most.
I've been good with smartass but i'll definitely check out the others since you guys vouch for them. With froyo I got four days on my extended battery with ultimate juice. Now I get two.
I had the same question regarding smartass vs. SZ gov - I've been using smartass but I'll give interactive a try. Thanks!
I have googled it but they don't really explain much and only explain 4 or 5 of them. How about
Smartass
Smartassv2
Scary
Superbad
Greaselightning
Ondemandx
Minmax
And links or if you could just explain would be great. I wish setcpu would just give this information instead of making us just guess which one to choose.

Also I'm using ondemandx but I don't know the difference between it and ondemand

sorry to interrupt you... but what are governers??
Unfortunately I've never seen a comparison between those algorithms (which as far as I know adjust frequency and voltage depending on load). It would be nice to have a full comparison..
i have mine set to ondemand and i set my own voltages using incredicontrol. I'm at 1.7mhz and very stable.

Governors are:
AFAIK governors control how the processors change speed. When using the "On Demand" governor, the CPU will ramp up to the required speed quickly. When using the "Conservative" governor, the CPU will ramp up at a slower pace to conserve battery.
Well I would like to know about the new lag free governor found in cm7. That link above doesn't mention it.

Lagfree governor
'lagfree' - this driver is rather similar to the 'ondemand' governor both in its source code and its purpose, the difference is its optimization for better suitability in a battery powered environment. The frequency is gracefully increased and decreased rather than jumping to 100% when speed is required.
Took me 3 minutes to find it.

Hello...can you post your settings about cpu governor.now my defy is set from 2nd.init at smartass governor and I seems like it is using the higher frequency more time then on-demand governor. I have latest cm7 from quarx and 2 days is the max batt life, but using hsdpa quite often
Sent from my MB525 using XDA App
Well
2 days sounds good. OnDemand works better for me like 5%+ but you need to tweak all the levels after VSEL to see some differences. Try asking, searching for a thread where they tweak all the levels and it's reported to give a boost.
Here's a post I made a few weeks ago regarding the smartass governor:

i don't use Setvsel...i tweaked vsels from 2nd init.

Hey everybody, so I'm a pretty huge noob when it comes to performance settings. I only recently read through the Understanding CPU Governors thread, and I get that part pretty well. I just flash the new AOKP rom for Primo C, and decided to go with the Scary gov. What I don't understand is what the heck is the io scheduler, and how to use it. Also, what are some optimal min/max MHz settings for the One V?
I chose Scary for battery life, not so much for performance. I don't need a high performing phone, but I do want my battery to last those extra few hours. If someone could give me some feedback on how to use this stuff, I'd really appreciate it, so that I could quit asking every few months.
Thanks.
Min try not setting below 250mhz and max 1450 please dont oc it above that ur motherboard will fry...and if u want high performance install,a custom rom and kernel, if u oc.it u will get high performance but low battery....and vice versa....
Hope u understood click thanks if it helped,

The I/O scheduler is reponsible for how data is "transfered" from storage
This includes when it will be written back if dirty a.s.o
So it influences the I/O performance.
Actually the default deadline is a good choice to use

Ok im looking at kernels and im not going to ask "whats the best?" but im really not understanding the difference.
What im looking for is a kernel thats stable (that seems like all of them), one that allows under-clock/volting (and any other batter saving tricks) and one that will work well with my rom (XenonHD rc3) as most of the kernels seem to be using anyrom i dont think this is an issue.
i have been using the stock kernel then tinys kernel but im wondering if Zen or Air are going to serve me better?
Here is the order im looking at things
Stability
battery
speed
cosmetics
From what i can tell the governors dont seem to matter much as long as there are a few available (performance, interactive, conservative, power-saver) and the schedulers are even less important as they can handle normal use just fine. SIO or no-op or CFQ all work just fine for me. never tried FIFO but it seems kinda restrictive when multitasking
So from a development standpoint could someone explain whats so different in TINY, ZEN, and AIR i would much appreciate your input. They all seem to start from google source, are the compiled different?
Ok so i am trying Zen and i like that the CPU can be clocked lower. but im still not sure about whats best for me. A comparrison chart would be grand but i have no idea what to compare
The major differences between kernels are what kernel version they're compiled from, what modules are compiled into the kernel, which I/O schedulers are included, and which CPU governors are included. Depending on what the kernel dev has included, the kernel tends to run better or worse on specific devices. Unfortunately, it tends to vary quite a bit even within a single device line.
Zen is the best one I've found yet for my device. Others swear by Franco, Air, Trinity, etc. It's really a matter of trial and error on a device-by-device basis.
Finally, your statement about governors and schedulers not being that important is a bit wrong, in my opinion. Schedulers are definitely the lesser of the two, but depending on your usage, you can get a little bit of an I/O performance increase by using the "right" scheduler. The same thing goes for governors. A properly tweaked governor can save a bit of battery and/or boost your performance. Just like the kernels themselves, though, it would vary device-by-device and based on the user's usage type.
