[Q] System I/O Speeds - Samsung Mesmerize

I have been looking at the system I/O speeds on my phone and running Antutu benchmark and it shows my system I/O at really low marks at 50-65. Ive seen scores as high as 150+ and i was wanting to know how to do that please to speed my system up.

If you use the OTB kernel there is an option within Voltage Control to switch schedulers, you may see some speed increase there but probably not enough to make a big difference.
Most of the I/O scores you see (quadrant) are bloated scores and are not accurate benchmarks

Ive messed with the schedulers and didnt see any difference. And i dont use quadrant anymore bc i found a better benchmark app called antutu.

Honestly I use lindpack for benchmarks. It measures MFLOPs and from the info I can find that is the measure of the processor power. It is the same method used to test the worlds supercomputers. Before OTB I would get about 13 MFLOPs. After OTB I get about 16MFLOPs. Hope this helps ya.

[Q] Quadrant Scores for the 7 Plus?

Hi guys,
I have a Galaxy Tab 7 Plus 6210 (WiFi only) and I'm getting Quadrant Scores mostly close to 3250. Meanwhile a lot of the reviews I've read online report 3600 to 3800.
Should I be worried?
Maybe off topic but I think people should stop using quadrant. It's really old.
The CPU part it does not work well with multicore and for the GPU part almost all tests reach FPS limitation set by ROM. So the score of it cannot really differentiate performance now.
It's also WAY too sensitive to I/O tweaks - disabling per-file write syncs gives you 600+ points on Quadrant which is insane.
Similarly, there were hacks (like the Stagefright hacks) that would cause Quadrant scores to skyrocket (I think people were figuring out how to hit 3000+ on Captivates) but would make real-world usage of the device utter crap.
I know of Quadrant's shortcomings - but my theory is that for two devices that haven't had any significant modifications to them, the score should be similar (no matter how flawed Quadrant itself may be to tweaking)
not too shabby for stock, hangs at I/O 2of 4.
That app is useless imho... rebooting my Tab bumped it 600 points
try AnTuTu benchmark. I got a score of 6030 with v6 Supercharger and KAK tweak.

[Q] Overclocking and FPS

Since Imnuts' latest kernel release and nitro's eclipse I've been none stop playing with my phone just like the day I got it. Anyways, I've overclocked the cpu to 1.3ghz. Very stable and no issues with stability. However I been using Quadrant to monitor changes I make and the impact it has on the phone. It seems to me when I overclock (any frequency) my FPS on my 2D drop way low and the 3D also drops. This significantly reduces the score of quadrant. I know quadrant doesn't mean anything but FPS difference means something. Also, upon investigating, I found if I change the govenor it also has an impact on the FPS. What is happening here and why?
thanks for any input!
I have actually noticed this also. Very curious.

This is how I found the best settings with the best performance. Set you governor to "on demand" and set frequency starting at 1100 then run quadrant, the first graphic is wall paper (yellow) appeared, look at the FPS, it should read above 20 (like 22, 23 or more), it's safe to increase your frequency to the next level. When you see the pfs in the wall paper scrolling drop below or fluctuate below 20 then the previous frequency is the highest you can use or max you can use. Once you done with this you can set the governor to anything you like, but I found that on demand is safe and save battery the best, since it's only use high frequency when needed. Min frequency I set to 200. try to run at least 3 times before move on to a new setting. Also I kill all running apps before running the test. In a normal situation you should be some where around 1200mhz and quadrant should be around 2100-2200. If you have a premium silicon chips, you can see higher frequency and quadrant score. Additonal setting for undervolting, try to decrease every frequency voltage by -25 then try -50 see which one is better for your phone. IMO, I think -25 is slight more stable. I also found that on demand is as good as kickass setting. Good luck.

Try 1.2ghz with on demand setting.

Actually interactive, conservative, smartass, and powersave are better at battery saving, and smartass and interactive are also better at raising the freq when needed.

My phone survive at 1400 freg with on demand but not with any other settings.
With Tegrak Overclock Ultimate with Interactive X governor, I am 1.252 GHz at 1.285 volts. Minimum scaling at 200 Mhz.
I am stable at 1.3 with 1.33 volts, so I decided to drop the voltage down to 1.285 and clocks down to 1.252 GHz. I didn't think that 48 Mhz was worth .45 volts.
My Quadrant score after 5 runs @ 1.252 GHz is 2649.
If you want "accurate" numbers in quadrant, you should only run with it set to a min/max speed that are the same. For some reason, Performance doesn't lock the CPU to the max clock speed, possibly due to adding in more steps. So if min=max for the clock speed, then run quadrant, you will get more consistent numbers. If you leave min and max separate, the governor may step up at different points (or down), causing inconsistent results.

No argument here, right on!
Thanks all for the responses. @Imnuts thanks for the insight. I set the min to 1400mhz (same as the max) and set the govener to performance. I received the highest FPS ever and received a score of 3112. By far the highest yet. 1400MHz is set to -75 mV. 1300, 1200 mhz are disabled and all others are -100mV and up. I'm not sure if it is really stable but it works without any restarts of FC. I guess this test kinda proves quadrant isn't a true test of the performance of your phone.
also, does our phone have a fps cap?

[Q] Infusion coreA kernel may has some problems with GPU in zeus

I`m running zeus 5.2,everything is good.thank you dman!
but i notice some questions:
If you choose the governor ondemond,there is olny 50fps in game or neocore test,it is a little bit lag.But high cpu and IO score in quadrant(3300)
then you change the governor to perfrmence or conservative or interactiveX
you`ll get 56fps in game and neocore,the game runs quite good,but cpu and io score is lower in quadrant ( 2100 point)
I wonder what`s wrong with this problem?It someting wrong thunderbolt or kernel ?
thank you for your help.
neocore and quadrant are a joke. besides that kernel is no longer supported as all the old kernel devs left and there hasnt been any new source code to build from.
file system scores on quadrant are laughable, infact dont pay any attention to quadrant if you can help it, miui and a tweaks script can get you near 5000, that doesnt mean you increased capabilities by 5 times over stock.
if you want a file system benchmark then i dont know what to tell you, i dont know of any good ones. if you want a cpu benchmark then use chainfire bench. if you want a gpu bechmark use one that can actually bog down the gpu. neocore isnt enough of a challenge for anything with a modern gpu, thats for old snapdragon phones (nexus 1, incredible, evo....) or low level phone. the kernel limits the fps to about 56 fps, the reason the different governors show lower is that the thresholds and logic is different so it doesnt step you up as aggresively. being 6 fps off the cap doesnt show a deficientcy nessessarily, it might just be some lag in the step up or a high threshold for step up. or there may be a slight issue with that governor on that kernel.
Dani,thank you for your answer
I`m totally agree what you said that neocore and quadrant are a joke ^0^
I dont care the score but because i`m a noob,so I was curious with some something strange.
you could feel the different between 50fps with 56fps in some games, such as Dungeon hunter2 or bcakstab HD,but not in doodle jump :)
maybe those kernel is no longer supported,and problems will not be solved,so I only hope that some new kernels come out soon .LoL

Cheating on benchmarks

Why do people really care so much about benchmarks. i just seen something about Samsung devices cheating the most. specs and benchmarks don't mean anything. Also doesn't the CPU Governor control the CPU clock speed. So When you're running an intensive app it ramps up the speed And then lowers the speed when its not needed to save battery? Also if your running a custom kernel ans set it to max performance it would tell you if the stock kernels cheat. i am just sick of seeing all this stuff about cheating on benchmarks
Is not because of the benchmark, is because they cheat.

Yes brother.
Benchmark is really just gives you an approx range whwre your phone stand and its stability and other things.
But some developers use GPU for rendering and for smooth so in that case the Benchmark is low
As it is calculated on the basis if CPU Performance.
And
Some of the custom kernel have auto configuration of the CPU oc.
That helps the phone to get perfectly stable whichout adjusting.
And battery life of android.

Yes,
Actually it's not Cheating juat a small eroor or manipulation.
But some are really Good and Check perfect if your GPU Rendering is OFF

I am confused how they cheat. Do they benchmark it with a benchmark app then published inflated results or do they bump up their cpu when benchmark app is detected to increase their score similar to overclocking in rooted phone.

there's a quadrant cheat i found on playstore upping my quadrant score by 1000 points

[RESEARCH] Overclock on Qcom useless due to screened SoC's

Some weeks ago @Quarx told me that he tried to overclock his MotoG. At a first look it works. The system is stable and cpuinfo apps show 1.9GHZ.
BUT: there isn't any performance change. Then I checked it on my device(Xiaomi Mi2) - exactly the same result.
I watched a video about Nexus4 overclock: https://www.youtube.com/watch?v=96hsPe-JH2M
As you can see there isn't any change, too(the minor differences are just random).
Then Quarx found a very interesting commit in MotoG's kernel log:
https://github.com/Quarx2k/kernel-moto-g/commit/ed82c3f26ec4a7ab39a436647643bdaf71dcb67a
The message tells us, that QCOM devices normally are "screened" which basically means, that if your max freq is 1.2GHZ, it doesn't matter what you change in the kernel source. it will always be 1.2GHZ even if it shows 100GHZ because the SoC is limiting that.
There are some older SoC's with adreno 2xx which seem to be overclockable without any problems.
But all new SoCs seem to be screened which prevents overclocking.
Some more tests of other devices and SoC's would be helpful.
I'd recommend you get a buttload of single-thread Linpack benchmarks at different frequencies and do some statistical analysis. Maybe make a Google Form where you can input Device, Frequency, and MFLOPS
Linpack because it's exclusively CPU, doesn't vary much between devices of the same model, and scales nicely with frequency.

I think Linpack isn't reliable enough because it's completed too fast. For me it takes 1-2s to complete and the result variate's very much.
Sth like Antutu(only the CPU score) with performance governor and maybe even on a clean install would be better.

So how we can really test it? test in game to see if FPS get more high? I really dont believe that is just a placebo effect, in my kernel with 1.5Ghz I really feel the speed and will test when i finish the OC of 1.8Ghz.

well I only said that linpack looks unreliable. Antutu or other cpu intensive benchmarks should work just fine. Just ignore gpu benchmarks, because the gpu is definitely overclockable.
