As by the title, I get a low score on CleanROM 3.7 based on ICS 4.0.3. My result is just 1700. I haven't found any benchmark result based on this rom but I know that stock should get at least 2400-2600.
Has anybody benchmarked on CleanROM?
Why does it matter? Bragging rights, or pissing contest?
Actually the score doesn't really matter but I've noticed a slowdown after flashing CleanROM.
Haven't noticed any lag at all.
Have you benchmarked quadrant? Also, the slowdown is more noticeable when scrolling menus and some heavy designed websites.
I don't know why people bother with Quadrant, it doesn't work correctly on dual-core phones anyway.
Actually don't really bother on it. But, as I said started to be doubtful of some lags compared to the stock rom and I used quadrant just to create an idea if this was really the case.
By the way. Ver 2.0 is optimized for multicore phones.
Quadrant is a terrible benchmark.
Use Antutu.
Tryied Antutu and got 3387. Checked a bit around and found that a score of 5000-6000 should be normal.
Ok, rerun antutu after restarting the phone and got around 6200. What really bothers me is that even after killing all task and running any benchmark, I notice that scores are usually noticeable lower than on a first run after restarting. And more important, the phone is slower. Seems like services are still running and using available resources.
I use Advanced Task Killer by the way.

Don't ever, ever, ever use task killers on anything past Froyo.
They harm the phone and do not do anything, it's all placebo that it does.
There's countless threads about it.
Delete it.
Done. Thank's for informing. Now I'm asking myself why they are still some of the most downloaded apps on the market when 90% of Android are on GB and up.
Because a friend of friend told them long ago to get it.

Imo the only benches I care about are GPU benches. Quadrant is utter garbage, remove it and do yourself a favor. Nenamark 1 / Nenamark 2 for GPU benching is nice.
well, scrosler puts fastboot in his rom, which kills all running tasks that are not core.
Myself, I'll occasional open System panel app if the phone is acting up. Very occasionally.
On cleanrom I haven't noticed any slowdows.

So I've gotten anywhere between 2.5 to 5.1 MFLOPS using various ROMS and have yet to be able to notice something incredibly different.
710...768...806 - What does it matter? What program other than Linpack shows a sizable difference? Sure, maybe things open quicker? What am I missing here?
I read all this about achieving high MFLOPS and OC Kernels yet I still can't achieve smooth game play on 16 bit emulator on my phone with 5 MFLOPS.
MFLOPS mean jack when there is little way to observe the difference.

Linpack MFLOPS - measures the floating point performance of your phone.
710...768...806 - refers to CPU frequencies
increasing the CPU frequency should equate to better general-case performance, including things opening quicker as you mention, but also other types of general snappiness like moving between screens and so forth.
"I read all this about achieving high MFLOPS and OC Kernels yet I still can't achieve smooth game play on 16 bit emulator on my phone with 5 MFLOPS." - This may have less to do with the performance of your phone and more to do with the emulator itself. Emulation is a surprisingly CPU intensive operation, especially if the emulater isn't well written. Rather than looking a ton into overclocking and JIT, etc, maybe you ought to look for a better piece of software.
Yea,
I've tested most emulators. Wish there was an Atari emulator!
Thanks for the response.

Haha Awesome
it looks like to me that everyone is look at the wrong things.
for example:
I am running a Tom that is getting on a average of 4.9 mflops.
I get smoother screen changes....
streaming videos online is so much faster compared to a 3.0 mflop rom. ...
tubetube and other....... websites.
to me everything I do is faster...
I.don't play game on my phone so I don't know how that is.... but everythng else I do is very much faster.
I love high mflop roms...
I have notice about mflops is that it matters about the kernal that u use.
Isn't it true that the MSM7201 in our phones is already overclocked to get to 528mhz as it is? I see a lot of different places saying Qualcomm chips in general are just not worth overclocking... and since our chip is factory overclocked to begin with... just seems like we're pushing the already-pushed here. But the way this board goes crazy for overclocking... it's contradictory. I don't know what to think, cause I've run Linpack myself and gotten ~4.9 with JIT + OC versus ~2.5 without... but I'm with the OP on this one... only difference I'm seeing is my battery draining faster and my phone getting physically hotter.

I have OC and JIT and getting about 5.1 mflops and haven't had worse battery life or a hotter phone. It could be the battery I'm using but meh (got a replacement one that's 2000 mAh) but I got worse battery life on leak 2.1 than with the rom I'm using now that has OC, JIT, LWP, etc. I can go about 8 hours with heavy texting, moderate internet usage and my lwp's running and it only goes to about 65%
so OC and Jit don't make that big of a difference in gameplay?

What the OP and all the respondents are noting is frankly quite typical of what happens when performance tuning focuses on a single benchmark: the results obtained are essentially meaningless for different kinds of activities on the same device.
That's because there's a whole chain of dependencies that are specific to a given task, any number of which could become the rate-limiting factor; and a different task on the device will have a different set of dependencies and therefore different rate-limiting behaviors.
For instance, let's take writing to an SD card as an example: there's really no way that OC'ing will speed that up in a measurable way - because the CPU isn't the rate limiting factor.
That Linpack benchmark measures floating-point performance using a software library (as the Eris has no hardware FP capability). Most of the apps on the phone do very little FP work at all. But, it's not a bad test of CPU speed, because it performs no I/O. It also may not be very memory bandwidth intensive, either (if the problems it works on stays in the uP cache and there are few page faults).
OTOH, a game emulator needs to write to the graphics display (at a minimum) and possibly also do read I/O from flash.
Different task, different results. Sometimes things can be improved by hardware or firmware; sometimes the software itself needs to be improved.

Thanks for my laugh of the day on that one.
What I'm trying to get at is -
I should be able to play, at the basic level, Sonic or Mario - Without issues.
At the very least
I prefer roms over market games any day (Sonic, Mario, Zelda, DK-Country) and it cripples the phone, at least in my view, that I cannot enjoy the fruits of old games.
Although, I was able to find some old Atari games - which, thankfully, work without stuttering.
I am running Vegan 5.1.1, Clemsyn's Kernel v9
My quadrant scores seem low..my first run was a 1948, since then I have not achieved anything close to that (1600s), and definitely have not reached the 2400s that most with Vegan report.
I mean, I am not noticing any issues with my tablet's functionality, but I do not want it to be slower than it should be.
Any thoughts on why I am experiencing these low numbers?
Thanks in advance!
I have run quadrant a number of times since, and I am definitely hovering in the mid 1600s
I'm getting around 1900 on mine, and I'm running 2.3.3 one with Honeycomb elements. I haven't messed with the jit settings (that can help a lot). I'm also running ADWLauncher... since thats always running, that could be some of it. I'm not sure if mine is normal for the rom though.
If you aren't noticing anything negative from a low score, I wouldn't worry about it.
Well, I notice some lag occasionally in Dolphin, and in games after having run other apps for a while. I just have no prior experience with tablets to know if that is normal or not

That is true, everything I've read indicates that Quadrant scores in not necessarily an indicator of overall performance. That being said, my first scores were in the 2000+ range. I've heard that switching to ext4 would boost that even more.

I do notice this as well, running TNTlite 4.4.0, and I do get higher quadrant scoress, 2200+. I'm new to android, but I suspect that this is just how it is. (Like when Windows gets bogged down loading programs is a little slower)
The lag I experience isn't anything terrible, but it is there forsure, especially when the tab has just came out of sleep. Doesn't really bug me unless I am in a rush to finish that angry birds level before I get back to work.
Hm...so I guess I just won't worry about it too much. There has to be some reason though that my are 500-700 less than yours though. I just worry that there is a hardware issue with my tab, or some software leeching processing power

Are you making sure to exit those games, (hitting the back button till you get an exit dialog) or are you just switching to home? It may be that those games are still running in the background. Search for an appkiller in the market and that'll also help you turn off other unwanted services running in the background
I've run quadrant before and after exiting everything, no change. Averaging 1660.
edit: And yeah, when switching from one game to another (or anything memory intensive), I make sure to fully close the initial app
I just upgraded to 4.4.0 from 4.3.0.
I saw score of 2400 drop to 1600 also.
System works great.
I am getting 2300 on VEGAn 5.1.1 with stock kernel
Sent from my VEGAn-TAB-v1.0.0b5.1.1 using Tapatalk
Go into settings... apps... clear data for quadrant and rerun... I get 1600s sometimes but after I clear data I get 2300s. 2500s on Calkulins ROM.
Also vegan 5.1.1 with clemson v7 & I'm averaging 2300 or so. I installed the 3588 nvidia drivers update I found in the forum somewhere and it boosted my score. Then again they might be already included in rom or kernel and its a fluke my score went up.
I'm also running vegan 5.11 and im scoring 1900 - 2000 except i am noticing functionality problems. I'm using vtl lancher and when i go into the app drawer and swipe to the next page, it lags and ends up dragging an app icon to the home screen.
Hey what would cause my java scores to drop using cf bench..I'm not sure what its measuring but it seems to have cut in half for no reason ..I think its at 1800 when it was like 4k before ..this isower than stock
Btw I'm on viper and helicopters #1 kernel ..with this same combo I was getting an overall score of 8k so I'm not sure what has happened ..and its not just the score I can feel it using the phone.
You got an app that is a cpu hog maybe, it could be a number of things. Reboot your phone and then clear out all your tasks using an app like Fast Reboot, then run a quadrant. Also an app like system monitor can show you what apps are eating up cpu and battery. Hope this helps.
I just noticed I got the same set up as you as far as kernel and ROM, its got to be an app in the background cause I get no lag whatsoever and im only over clocked at 1.5 with the screen on.
Edit again: maybe your over clocked too much, I read that pushing it too high can create lag also and be counter productive. With me 1.5/on demand seems to be the "sweet spot" for battery/performance.

Thanks for the reply..let me explain exactly what happened.. I had the setup I told you for a few days and I was using setcpu to Oc..at that time I.was getting about 8 k cf bench score and the phone was fast besides the fact that setcpu was acting funny..then I set up the Oc daemon and set it to 1.8 just like I had it for setcpu. I really liked the daemon bc the phone was super fast..I then flashed an icon pack..at this point i was still getting high scores..I then tried flashing a theme and after that is.when my scores dropped significantly and i felt a little slowdown..so I.flashed back to just the ROM and kernel with no theme thinking that the theme was the issue. Unfortunately I'm getting the same low scores. The java score is very very low. I dont have many apps and i didn't even re install any apps besides the cf bench when I re benched it
Try viruses superwipe, that might help.
Will do
..should you wipe when flashing another kernel
If its just the kernel just wipe the cache and dalvik cache.
I did superwipe and my java score went up 1000 points..I'm at around
6500 ..right on par with the gs2..so its better but not as good as before..but I'm happy bc everything feels good..since your running same setup as me if u can do a cf bench and let me know what you score is appreciate it ..thanks for your help
So I installed SetCPU today. Been testing the kernels ability to work underclocked at the max of 918mhz. Also set the scaling to conservative. After a days use it's been as good as normal full speed, 1512mhz
The battery lasted throughout the day, compared to my first two days of stock settings with only 6 hours of good use.
I'll keep playing. Still want to do some testing and benchmarks to make sure it's not under performing. But at least at the user level it seems to react the same.no lag.
I did confirm the clock speed out side of SetCPU using system panel.

Don't bother using benchmarks to rate a phones performance that is a fatal error there. Benchmarks never effectively rate a phones performance. I just go by how smooth the phone runs and it does it run everything I throw at it. If so gg pz end of story.

Benchmarks do have a some good uses... while comparing different phone models with benchmarks can be iffy, it can give an overall insight, (things like graphics capabilities with very GPU extensive games) but in the end user experience and daily use are the real judges.
Where benchmarks can be of the most use, is when comparing changes to the same phone model.
E.G. Comparing performance impacts of AOSP vs Sense, overclocking and under-clocking, and de-sensing/bloat removal.
When used for these reasons, you can get a really good feel for how changes are affecting your device overall. Even then, benchmarks are not the be all end all, and user experience is still important. As you may introduce lag or other performance issues that do not show up in benchmarks.
Which temp root method are you using? Mine isn't staying rooted long enough for me to justify using setCPU at all...
The new version and the one that comes with the newest clean tool stays until reboot.

Please let us know what settings you use that work for you.
I generally stay temprooted unless I'm going to be away from a charger for a bit and need BT (since you can't turn BT back on after temproot). I wouldn't have SetCPU autostart on boot (since it won't ever be able to get root access immediately after boot).
Meanwhile, I also set it to conservative and will see what that accomplishes.
A kernel needs to support setcpu, stock kernels do not. You need to flash a custom kernel, so you need a development phone or s-off.
Sent from my ADR6400L using XDA App
This kernel apparently does work with SetCPU. I've confirmed using other cpu monitoring apps that the clock speed changes are capped.
I own 7 android phones, and have been rooting, overclocking, undervolting each and every single one of them (well one I still cant get rooted). I know when the cpu is under clocked and when it is not. Been doing these tweaks for 4 years now. If you use a tool like System Panel, at stock settings you can see the max cpu around 1500 on our little bad boy. When it peaks out the clock speed is shown. When you under clock it, then check again it won't go beyond the max cpu set in my testing I put a ceiling at 918mhz. System Panel reported full CPU usage (100%) at clock speed 918mhz. Typically with stock kernels, your absolutely right, changes to SetCPU do nothing at all to the real cpu. Which is confirmed, when I reboot and dont have root, if I attempt to use SetCPU and make the changes, System Panel reports 1500mhz (roughly) at full load regardless of what I set it to in SetCPU. If I did this to any of my other phones with stock kernels, you are correct it makes no difference as SystemPanel reports the stock max setting.
No I'm not being mean or aggressive, just saying. =-) And no don't believe me, but test it yourself and confirm or prove me wrong some other way and I admit error. Either way, half the fun is messing with the phone and trying to get it to do things it should not do.

In my view, the "benchmarks" would be an OK measurement if you were comparing apples to apples.
I tried running both Linpack and Quadrant on the very recently and dearly departed Incredible right after a fresh reboot and having charged the battery overnight...when the thing should have been at it's freshest.
I got wildly different scores each time I ran it after a reboot...knowing that on both programs the scores would improve the more times you ran the test.
It didn't seem to me that either program was a reliable indicator of what my phone was capable of. I didn't even trust them to tell me whether something I'd done...cleared cache or deleted bloatware...had any real effect.
It simply boils down to how the phone feels. That's not scientific, but it works for me.

Linpack and Quadrant are not reliable benchmarks. TBH I don't take any of the benchmarks seriously, they are more for entertainment for me. But to each their own right?
Yeah some of the benchmark apps are a bit unreliable to say the least...
If I use one, I try to use ones that Anandtech uses. I trust them to find the better benchmark tools.
So I overclocked my GSII to 1.6Ghz, and ran benchmarks and it was blazing fast. So what's the point of overclocking other than running benchmarks? I'd rather not have my processor running at 1.6Ghz all the time and draining battery power. I actually prefer underclocking to save power. So my question is - how else can I benefit from overclocking my device?

Well its obviously to have your device performance better. Honestly it's not really practical to run higher than 1.2 ghz though.

OP even if you crank it up to 1.6GHz, unless your isolating that step, your phones not using that clock speed unless your doing sh*t on your phone. It will increase how fast apps or menu's open navagating throughout the phone. Your making the CPU think faster so your phone ends up doing its tasks little and big ...faster

The benefits of overclocking you ask? Let me tell you just a few.
1. For every overclocked phone, one dollar is anonymously donated to poor and starving children, families, and college students across the world [citation needed].
2. Overclocking your phone emits a low frequency gamma wave inhibitor which in some cases, tested by prestigious scientists, has proven to protect you from harmful UV rays from the sun, nuclear fallout, increases neural synapse action in the brain, lowers bad cholesterol AND blood pressure, increases lifespan up to a minimum of three years, and is a natural antimicrobial agent that also interacts with your white blood cells to not only increase output and strength, but also breaks down the DNA rebuilding process by inhibiting protein synthesis in a wide variety of foreign microbes in your body.
3. Overclocking has been used to successfully treat sever depression, obesity, dementia, and AIDS.
4. With an overclocked phone, it's been observed waiting times for and inside elevators is severely decreased.
5. Bad driver? Accident prone? Overclocking has been shown to heighten driver awareness and overall skill.
6. It speeds up your phone on a day to day basis, with some, but not terribly noticeable battery drain [citation needed].
Sent from my SAMSUNG-SGH-I777 using xda premium
Overclocking is entertaining. But I'm running the Unnamed rom on my device and have it UNDER clocked to 800mhz. Crazy good battery life and zero lag.
Overclocking is pointless as it runs everything great already. I'm waiting to overclock until my phone is outdated and my contracts about to expire.
While its rather easy to do there really isn't any benefit to overclocking the SGSII. Yes, it'll run a little faster and your Angry Birds might run smoother (really? ), but it'll also mean a little more heat and more battery drain all to accomplish something you really won't be able to get any real advantage from.

For this phone, it's pretty much useless. The phone runs great without the faster clock speeds.
On the other hand, if it was a snapdragon processor, you'd need 1.5 GHz just to be marketable next to this phone (and 1.8GHz to perform as well in day to day usage.)

Most people overclock for a smoother/snappier experience. I notice that roughly 20% increase in scrolling/tabbing around. Also you can think of it like this:
1.4ghz will finish tasks faster then 1.2, that way taking less battery. You could also undervolt that 1.4 to 1.2 (1275mV), so your finishing tasks quicker while draining no more then stock.
I switch between 1.4 and 1.0 every other day it seems. 2 months later, still looking for the right one for me. 1.6 should only be for benchmarking imo, epeen.

It's not that simple.
There are dozens of bottlenecks in these devices (and any other computer), and 9 times out of 10, it's NOT the processor. Persistant storage, RAM, bus speeds, etc - all those things will ensure that a 10% bump in processor speed will NOT give you a 10% decrease in run time for a given typical application. In many cases, you'll see no speed increase at all, as it takes the same amount of time to flush to persistant storage no matter how fast the write cache fills.
I'm not suggesting that a person shouldn't O/C, but don't be surprised when going from 1200MHz to 1400MHz makes no visible difference other than the battery draining slightly quicker.
I know someone is going to respond that the processor will bump back down to a slower speed and therefore it runs at the higher speed for less time, etc. However, unless you have the governor set to poll for usage so often that the governer is driving your clocks up to max, it's not going to poll often enough to make much (if any) difference.
Think of it this way: We both own a mustang, but mine is a V6 at 220HP and yours is a V8 at 300HP. In theory, yours can accel faster and maintain a higher top speed. In reality, neither one of us can go faster than the car in front of us (but you'll burn more gas doing it.) (Of course, you'll have more fun in yours.)
I hope this helps with a very common misconception.
Take care

Very true. Also I am guessing in gaming, that OC will drain your battery quite well.
Consider I mostly do Web browsing on my phone (I need a tablet), 1.4 is a much better browser experience imo. Worth the 100mV.

Excellent analogy.

While for now Overclocking is mainly just done for fun im hoping that closer to my upgrade time that i will be overclocking for more actical reasons. That is the way it was for my Captivate. I enjoy trying to push my hardware to its limits. Ive gotten my GSII so far to a stable 1700mhz but i think i can squeak out a little more speed especially with the gpu down clocked a little. I run it at 1400MHZ Though with the gpu forced at 267mhz.
