According to this link, the upcoming Epic 4G has an I/O benchmark that is much higher than Vibrant (and therefore the similarly handicapped Captivate and international and Bell Galaxy S i9000). I started wondering whether this is due to actual hardware differences, or if there have been tweaks incorporated into the firmware that are helping. Then I found an Epic 4G system dump here. I haven't personally downloaded the dump from that link, because even if I did, I wouldn't know how to find anything. Could someone with more ability study this dump and possibly learn something useful for us?
I have also heard reports that Epic 4G has a GPS that works well. This is less of an issue for me personally, as I am on JH2, and find my GPS adequate for the occassional use I have put it through. This is another area that might be worth looking at.
Edit:
alternate Epic 4G dump download location
Interesting to say the least. Wonder if they dumped RFS or if they just figured out how to optimize it. The hardware differences between the devices shouldn't be significant enough to show that big of an I/O difference.
Who knows, maybe this indicates that Samsung has an idea what's going on with the performance issues and will eventually filter it down to the SGSs variants

QFT .................
I am going to go ahead and download the system dump zip file for archiving purposes. I'll probably put it up at an alternate download location, once I have it.
I'm not 100% sure on this but I think the Epic's total internal memory is NAND (1GB) unlike the other phones that use an internal SD card. Much different memory transfer speeds.
Thats why the one lag fix works so well, it copies data/data to the internal NAND.
I am already running the gps fix from the dump(haven't tested it yet). There is no lag fix as far as I can tell. The epic gets 850+ in quadrant. If it had a lag fix it would get a lot higher score.
I believe derek4484 is right on the 1gig of NAND. I just checked it out on a review site.

Yeah doublechecked derek too... it appears it comes with 1GB ROM only, all other storage is via microSD.
False alarm =P Samsung didn't fix or optimize anything, they just used a cheaper, more shortsighted method to avoid having to give up their precious RFS
Those test results are questionable. You can click on the link under the graph and compare other phones. They have Droid X edging out SGS in linpack: SGS- high 7's; X- low 8's.

I dont think they are right either. If the phone had that fast of a file system it would kill in quadrant. The epic has been reported to only get 850+ in quadrant.
Unless you're actually running an epic, the GPS fixes out there only dump the GPS files, so it wouldn't do anything to indicate the speed of the actual Epic in terms of file system performance =P
why would they let sprint have the nicest version of the galaxy s ugh -___-

No I am saying people with epics have tested them with quadrant and are getting 850+. I cant see it getting so high scores from laptopmag.com under the file sytem benchmarks but only get 850+ in quadrant. laptopmag.com says the droid x file system benchmarks the same but it gets over 1200 in quadrant with slower cpu and gpu.

Unless youre comparing the same phone. Especially when one with lag vs one without it get the same score. Even though quadrant isn't the best thing to use you can still use it to show an improvement after a fix or a mod from the base number. So his question was why do the phones get the exact same score but one has lag.

Quadrant only tests throughput bandwidth not latency, etc. The internal NAND may be just as fast in terms of MB/s but it could have lower latency or other charecterists that Quadrant does not test.
So I've been messing around with different roms and kernels for the past few weeks and finally settled on CM6 6.1.1, and the snap 7.6 bfs kernel, for stability and speed. I turned on the turbo mode with snap, OC'd to 1152mhz (freezes at 1192), killed all apps, and ran quadrant.
[Picture of a 2330 benchmark screencap was supposed to go here, but I don't have eight post haha]
I know thats pretty good, my scores average from 2100-2350, but I'm looking to make it even quicker. What can I do?
Thanks!

Benchmark scores don't matter. I don't even check them anymore. Wether I get a 1400 or 2200 its still gonna dial a number at the same speed. Im not playing call of duty on my phone or anything. I want efficiency.
A benchmark does not actually show how fast your phone is....
Cyanogen himself stated this.
quadrant scores =/= to your phone being 'fast'.
But if you care about synthetic benchmarks then you could trick your file system into giving you quadrant scores in the 3000+ range.
by the way thanks for posting this in the relevant subsection of the evo forum dedicated to development this will absolutely further the development of android.
Yeah man, don't worry about benches. If you want to brag about how high it is just PhotoShop it. It's all about smoothness and real world performance/battery life for me. Just find what setup works best on your phone
Edit: and this goes in the q and a section

Also keep in mind that the EVO's Snapdragon CPU was never a problem, it's still competitive even with the newer CPUs (with the exception of the upcoming A9's both single and especially dual core). Most of the "hacks" that raise the Quandrant score over 2000 are just that, hacks. They manipulate the other tests (non-CPU specific ones) to raise the score and make you think that you've just achieved some kind of new level of performance when in fact you'll see pretty much no difference.
Over clocking will help a little but like I said the problem isn't the CPU; a lot of the lag you may see on the EVO is because of the GPU. Nobody has figured out out how to overclock the GPU so over clocking the CPU will make no difference with the GPU. There have been some improvements in the drivers and if you're running CM or MIUI, you already have them. Gingerbread slightly improves some of the core graphics in Android so you'll see a boost over pre-Gingerbread Android but I think what we should all be waiting on is for the new Adreno 200 GPU drivers that Google will release when the OTA 2.3 update for the N1 drops. It wont magically make our EVO's into Nexus S' or anything but I wouldn't be surprised to see a noticeable boost in performance.
Oddly enough, I'd rather have the transition animations that come with some of the custom ROMs, even if they take longer. They provide a much more "fluid" experience. I don't like the jarring, speed-driven, animation-free transitions that come with stock ROMs, because they lack polish. As soon as I saw videos of those animations, I was in love. LOL. Seriously though, lag and lack of animations (which consequently actually help hide lag and load times) are the two things I see holding back the polish of Android. Just as an example (not trying start a flame war here, people), look at the animation when going from portrait to landscape in iOS. Then look at Android's lack thereof. THAT is what Android needs-to actually FEEL faster, not necessarily BE faster. So try something like that if you want the phone to feel more fluid instead of just achieving raw benchmark speed. Again, just my opinion (kind of sad that I feel the need to put that disclaimer in every post lately).

Ok so ive rooted this toy, flashed the 1.2ghz kernal and ran quadrant on it. I hit anywhere from 1080 to 1180. Have setcpu on demand at 800 min and 1200 max so why on earth is my rooted nook color running android 2.1 and a flashed 1100mhz kernal hitting wayyyy higher scores? (Around 1280) doesnt seem logical at all. Specially cause this is an actual tablet and thats just a rooted e reader. Did I do something wrong?

Quadrant is a bad benchmark. It weights i/o far too heavily.
The Tabs RFS filesystems bring its Quadrant score way below where it should be, though in actual use it's very fast.
If you move to EXT4, your Quadrant scores will shoot up by around 80%.
Regards,
Dave
O sweet love of mary. 80% you say. Ok ive seen some posts redarding this ext4 thingymabob. Ill check it out. So if im understanding you correctly by changing to this my tab will perform even better than it does now? Or ill just see a genaric increase on this quadrant test that really means nothing? Sorry im noobish lol
Sent from my SCH-I800 using XDA App
Well, my tab is currently on ext4 and my quadrant scores completely destroys my rfs score taken earlier.
However, that said, i don't really feel any performance improvements except the satisfaction knowing that my toy is now on an open and faster file system as opposed to a propriatory and slower one ;-)

Quadrant scores aren't as accurate as people think you know...
Sent from zombie infested Gingerbread.
There's an app called OCLF that will transparently add an EXT4 area on the RFS filesystem without needing to convert the whole thing to EXT4, giving you EXT4 IO performance in an easily installable and reversible way. Probably your best choice for trying it out. Otherwise, for the complete conversion, you could try this Modaco ROM/Kernel, which includes a complete conversion to EXT4.
As far as performance differences go, it makes a huge (10x) difference to the Quadrant IO score (measured before and after figures), but no measurable difference to actual performance (measured real-world usage figures). Some people claim to notice a subjective difference, but I never did.
Im using the modaco rom and kernel with ext4.
And it does make a huge difference. I get around 1800 in quadrant now.

hi,
please be aware that the modaco kernel (rfs/ext4) will not work on CDMA Tabs.
from modaco kernel thread
This kernel is ONLY tested on a UK Galaxy Tab. It MAY work on other GSM Tabs, it almost certainly WON'T work on a CDMA Tab. If you have a non UK Tab and want to test (and know how to flash back to a regular version), then go ahead and report your results. At your own risk.

That's the point!
It makes a huge difference in Quadrant, which is a synthetic benchmark, but far, far less difference in real world usage - hence it is a crap benchmark!
Pre-EXT4 my Tab would pull around 1000 in Quadrant, whereas my Desire HD would pull around 1800. However in real usage, they seem to perform pretty much the same which is not too surprising as they are similarly specified. On EXT4, my Tab pulls around 1800 now, but still performs much like my DHD.
I so wish people would stop bandying about Quadrant scores because they are meaningless.
Regards,
Dave
If you look at the scores in quadrant , they are split by colour so you can see how good the graphics capabilities are for example and compare to other phones. The colour codes are at the bottom of quadrant by the way
Linpack is a better benchmark. Not perfect, but better
Not really - Linpack only tests floating point performance.

Taking Quadrant scores aside, when I made the switch from CF-Root to the Ext4 MCK, I really did notice a huge improvement in real world usage. I'm not sure if it is really because of the change in file system, but nevertheless thats the only big thing present in that kernel aside from CWM.
Everything said make sense and seems to be valid but let me share my experience.
I have Samsung Galaxy Vibrant and T-mobile Tab. Now both are using EXT4 file system and have fully functional recovery allowing for flashing straight from the phone.
Both now have Quanrant score around 1700-1800 and run very smothly.
Is I/O speed important? I think it is very important because task switching requires reading of huge chuncks of memory. Until read operation completed the user is essencially suspended. Multitasking is the major distinction of Android and lags associated with the tasks switching might be the most noticeable issue since its used so much. Converting of the RFS file system to EXT4 practically reduced lags to unnoticeable level. I don't need any better.
Another critical area for I/O is playing video and especially capturing HD video. The latter works only if I set internal storage and shut down all tasks.
This is work in progress but it seems it reached level of usability when most critical bugs eliminated.
It should be noted that the Tab is flashed with Rotohammer KM2 v1 ROM and Paul Obrien's kernel on a top. The kernel contains scripts converting the file system and flashing recovery. This combination works well, no issues so far.
Well I decided to give it a try and after install my quadrant is 2556 and linpack is 16.865 mflops at 1200mhz. Good scores but just numbers. I do however believe im seeing a bit of snap that I didnt have before when accessing my library. Still really unsure if this is a good thing as im not sure if I can use apps to sd anymore so I may uninstall at some point in the future but thanks to all you who helped the old man out. Atm im quite happy

hi. i have seen people here saying that "Benchmarks prove nothing" and even one of the Senior member saying so.
but what i have experienced after using Note and switching between different ROMS like Rocket Rom v22 and v23, Midnote, CheckRom and Stunner Rom, i have found that Yes the Benchmarks Do matter a lot in terms of just explaining how your phone will perform.
i mean i ran the bencmarks on all of these Roms and i used them all for about 4 to 5 days each, and i found that not all of these give equal results and not all of these are equal.
the Check rom performed the worst among all of these Roms. by the time i installed it, my phone started giving me issues. like the battery issue. whenever i connected the phone to the data cable and either connect to my pc or laptop or even the charger, there would a screen popup saying, battery removed! i did everything i could do to fix this issue but all in vain.
well the best Rom in terms of performance is the Rocket Rom. rocket rom gave me the highest scores and i found it to be the most stable Rom.
Midnote was ok rom. it gave me really good benchmark scores but there were lots of force closes.
i really dont want to talk about the CheckRom. it gave me the lowest scores and it proved to be the most buggy rom i have used, and then came the battery removed issue.
Surprisingly i, the ICS Stunner Rom was the Rom which gave me around 110000 score in the Browser mark in the native browser, but for the rest of the benchmarks it gave me normal scores.
so in my point of view the best rom for note for now is the Rocket rom, but if u want buttery smooth UI and 199% smoothness, go for the ICS Stunner. but the payoff is that u loose the SNote and the screen capture capability which i really love about my note.

Hardly proved! Far from it.
Benchmarks *can* give you an indication of performance, but *nothing* is better than simply trying out different ROMs and making your own objective decision.

Benchmarking could be slightly usefull when comparing different roms though optimalizations that are specifically made to reduce boottime, remove lag or whatever might not show up in te scores.
Using benchmarks to compare phones is definately useless, for example because Android forces you to run apps in the native phone resolution. The Note runs at 1280x800 which means any phone with a similar GPU but lower resolution like the standard 800x480 could synthetically outperform the Note.
Just to throw another point in there I know it can be easily disputed but take for example iOS and windows phone.
Windows phones are limited to single core and they still run smoothly due to optimization.
the latest iPhone 4s has a dual core A5s @ 800mhz, yet it still runs smoothly.
As mentioned above in the thread the only real way is to try out the phone for yourself.
Dude, it's obvious you're no scientist. You haven't proved anything trying to connect benchmark scores with stability and force closes. The only thing a benchmark could indicate is possibly smoothness. It's all about you simply trying different ROMs and finding one that is subjectively working best for you.
Sent from my superior GT-N7000 using Tapatalk
Benchmarks generally test specific capabilities of hardware: arithmetic calculations, GPU performance, etc.
That being the case they are a good yard stick for how the HARDWARE of different devices compare in terms of performance for the most part. Although software and the OS do obviously play their part, the tests are generally targeted at exercising specific aspects of the 'computer' rather than the overall OS.
OS performance is another, much more complex, aspect that benchmarks struggle to cater for. Small changes in benchmark scores between different ROMs is unlikely to tell us much. Somebody who reviews those ROMs and give a fair summary of the overall performance, stability, etc is a much better guide (like the OP, in this case - after a fashion!)
Check Rom is '****ty'?
What utter claptrap. Only proves you have no idea about how to set your phone up properly.
As for the battery issue, really? I've been running checkrom on 3 notes(mine,my wifes and my dads) and never had fcs, battery issues.

Benchmarks don't prove a ****. But I do it every time I try out a new kernel and waste 5 precious minutes of my life.
By the way, calling Checkrom ****ty was insult of all checkrom devs and ultimately an insult of xda itself, we are here because of all these devs.
You simply could have said it had lowest benchmarks or even it was sub par.
May I hope that next time you will carry general code of conduct and keep your ****ty opinions within your skull ?

probably but not necessarily, correlation does not mean causation,
each benchmark result is moreless the weighted average of few or more individual test results - now let's take Quadrant, which is (was?) heavily biased towards 3D graphics performance - how much is that representative of ROM performance under typical (non-gaming) phone usage?
PS.
Benchmarks may matter. Size matters more.

One thing apple got google and its oem beats. Dont fking look at the hardware and benchmark. Look at the user experience. Not saying ios and iphone is great for the folks who like to tinker. But for a dual core 800mhz iphone4 or ipad2 it sure runs a lot smoother than a note with stock touchwiz or some other launcher. Afterall u r using ur device, ur own judgement should tell u how good the device is not some program score. And there will always room for hardware improvement, but can the software follows? How many app is actually utilizing multi core process?

I got with Antutu benchamrk with stock rom and stock kernel about 6900 score
but it was so laggy and battery sucks. atm using Chrack´s rom extra small + speedmod v10 and its perfect no lags good battery life smooth but the benchmark sucked got like 4500. So benchmarks aren't the way to chose a rom otherwise there is no need to test and share experience with people

You don't know what you've been missing! This is for locked bootloaders so flash it with xrecovery. For unlocked bootloaders flash baseband .71 with flashtool first which also gives you the stock kernel. Then you can flash this kernel through recovery.

There is no such thing as a "Best kernel"! it grealty depends on what rom you're using, which settings you apply, ram, number of apps, cpu frequencies, governors and i/o scheduler. It also greatly differs per phone!!!!!
This one doesnt work on jaf rom!
It makes my phone to stuck at bootscreen!
And after flashing back to dooms kernel,everything is lagging,so i had to restore a backup!really a great kernel!
After flashing this My phone speed is like flashing the new Adreno ICS Driver its really slow
OK OK OK
I know benchmarks don't mean anything to you guys.

Man. I thought that would spark a reaction.

benchmarks are basically useless to the end user. fun to compare but dont think about it too much. a benchmark like quadrant can show a low score based on one area of poor performance but there is no guarantee that that will cause a bottleneck for data. it can also generate a high score based on one area and there is no proof that it is benificial. for instance we use voodoo lagfix that increases filesystem io according to the method quadrant usses to measure it by a fairly significant amount. it has never been proven to reduce hesitation of the phone outside of perception of the user, it is a good mod and i dont knock it im just trying to be objective. the thing is that data goes throught many componants and is held in ram and cached on the cpu, as long as the useage is light the file system performance is barely an issue because there are several systems that act as buffers, only when processing long sets of data uninterupted will the certain speeds become a bottleneck.
for a good analogy it is like drinking through a straw vs drinking through a hose vs drinking through a 1ft diameter pipe. the straw may slow the speed you can drink while the hose will not, but the pipe can supply much more water yet it is of no benifit to the person drinking because he can only drink so fast.
add cacheing into the analogy and it is like filling a glass through a straw a pipe and a hose. the glass can supply the person drinking as fast as they need it, but only holds so much liquid, it is enough in for on person but if several people want to drink (multi tasking or heavy usage) the staw will be a bottle neck, the hose will not and the pipe though overkill may make things marginally faster. now if there is alot of caheing it may be more like filling buckets and then the pipe may help but only when there is an enormous amount of data being used and in that case it needs to be processed just as fast, this is when the cpu can become a bottle neck.
it is very difficult to write a benchmark that can take this into account so it is hard to tell the usefullness of the data the benchmark gives you without reading the results of the individual tests it performs and making judgment calls.
we can increase our benchmark scores for filesystem by changing the filesystem to ext4, and even better by going with nilfs or nilfs2. we can increase sequencial reads by increasing readahead but that reduces random performance and waists resources. it all becomes a big balancing act and the end results can vary.
there are also ways to change the ram timing, the dalvik cache heap size, alter the ram disks, we can make the rom smaller and remove stock apps that are not needed, turn off background services that use resources, change polling frequencies to save resources, change governors to ramp up faster, alter and compile drivers for more efficient use of hardware, and a long list of other things. some work extremely well, some don't. some will make the phone snappier and have no effect on benchmarks, some will greatly increase benchmarks and not the feel of the phone.

:highfive:
Check out the 2d and 3d on the bottom of the top screen shot. I challenge you to get that good on both of them with any other kernel on our old x10.

No Comment... don't feel offended.. but
Did you read anything from the text Jeffrey posted?
You, well not you, but any good Dev can tweak a kernel and rom, to be good in Benchmarks.. while the general User Experience just plain sucks..
And to be honest, almost every ICS Rom with a somewhat decent optimized Kernel, has more 2D and 3D points than your screenshot.. i don't even need to post proof. it's a fact, even with the Xperia X10.
And there is no such thing as a best kernel...
Depending on the user, every Kernel has it dis-/advantages..
And thats why i think it's good for your ROM to support multiple Kernels, a thing many dev's are still missing, because when you have multiple Kernels, every user can use the Kernel best suited for his needs.

Ya, I read it. I haven't tryed ics yet cause i use my phone as my internet connection. OK thats fine. I don't really care if not anyone else uses this kernel but as for me its the best one I've ever had. Peace

Totally agree with this post
