[Q] ext4 advantages to the atrix - Atrix 4G Q&A, Help & Troubleshooting

So, everybody(somebody)((nobody)), explain to me the advantages of ext4 w/o journaling. I understand that write speeds for sd cards(?) is supposed to be better. My question is, where do we see the advantages? I ran an antutu benchmark on my phone and the write speeds were not the insane 150mb/s-ish write speed scores that Neutrino did when he posted that photo on his thread a while back, something more like a class 10 score IIRC. Anybody that can shed some light on this will receive my thanks!

Take a look at this post http://forum.xda-developers.com/showthread.php?t=1010807.
He explains well about boosting sd cards speed. You can do that by using Rom Toolbox which you can download in the Market. If you want to try it with Rom Toolbox, it's under Performance -> SD Boost and you'd like to change the default value, normally 128, to 1024 or 2048.

Everything just runs faster and smoother. You may not notice it, but if you revert back to a stock ROM, you will feel frustrated as it'll feel much slower/choppier.
And those insane write speeds were due to GT-S mod, not because of Ext4.

Ahh that was my blunder. Thanks for clarifying.

[Q] Benchmarks?

Does anyone feel like posting their benchmarks on the custom ROMs they are running? I know not every GTab will run the same but I would like to get a basic idea of what the hottest scores are. Thanks.
TNT Lite 4.3.x with stock kernel is ~40 fps (Nenamark) and ~2300 in Quadrant. On average.
There are definitely higher scores than that, with some of the other modded ROMs.
2200 with vegan 5.11 Benchmark Atuntu
Thank you guys for posting your benches. I had seen some one some where, posting that they get 60fps. Any one getting 60fps?
there is guide in dev forum where you can get up to 77fps, but the recomended is under 75.
You might mean the frame rate. The default is 50, but TNT Lite and gADAM up the frame rate to 60. At least one mod ups it to 77.
That's not really a benchmark, though - I assumed you meant something like Quadrant.
Im running caulkins rom and clemsyn's kernel #6. I'm averaging around 2400 on quadrant and 3000 on smartbench. The only thing faster on smartbench is overclocked xoom
It looks like most of the new ROMs run pretty fast. If i can get 2200-2500 in Quadrant I will be happy.
I get a little over 3000 qudrant

Are you bull****'n? 3000? i havent seen anyone say they are hitting the 3000 mark. I'd like to know what you're running too. Did you overclock? I dont think i want to overclock mine.

I have the same setup on my gtab... got 39.1 fps in nenamark, and 2399 in quadrant.
I just set my gtab up today so it doesn't have much on it yet.
There is a post in the development section by chengu that has a loopback fix that enhances read/write speeds on the internal SD. This makes the I/O part of quadrant way faster. I have posted on that thread vegan stock 10x average is 2500+. With the loopback fix its a 10x average of 3100 with peaks of 3333. So no its not BS but really how much do quadrant (or any other test) effect daily functionality.? It is great for bragging rights though, especially to xoomers.

Fyi: restart your tab 5 or six times, I know I sounds weird but it takes that many to streamline it completely. Let it stabilize after boot and then power down, wait 20 sectonds and and power on. It wil take up to six minutes on first boot and get less each time.
It uses boot time to write changes.
Have fun ;-)
loopback fix like others have said
Is there any down fall to using the loop back fix? Heat issues or failure? Why isnt anyone implementing this into their ROMs?
No adverse side effects that I have noticed. Most people have noticed a slight increese in playing video from internal memory and web browsing cashed sights. Read the thread its full of good info.

same with me, I'm using an 8gig card my friend got with his DX (pretty sure it's class 2 or legacy from before the class system). This tweak seems to have sped up my write speed by almost a full mbs/s and my read speeds have gone up even more,
4mb
For me: 16 gb ks >> 4mb>> 3.9 w>>18 r :d
I set my 8gb class 2 SD at 3456 & get this..
I'm running a Sandisk 32GB Class 2 (yup, you read that right). The SD Tool readings before the script is implemented seems to be fairly high, but they slack considerably after......
My readings are wild! Here's what I got, note that each time I run the test I use a task killer to clear running apps. Blue indicates readings prior to script implementations.
@128 - 7.7/11.9
@512 - 2.2/10.9; 2.9/11.7; 4.2/12.3; 5.7/12.3; 6.3/12.3; 6.2/12.1; 6.1/12.4
@1024 - 7.9/18.9; 6.4/12.3; 6.4/12.4; 5.3/12.3; 5.2/12.1; 2.5/12.1
@2048 - 7.8/19.8; 4.5/11.2; 8.1/11.4; 5.4/11.1; 2.2/11.7; 5.5/12.1

So.... I went with 5120....
This tweak is already applied in wolfbreak's ROM
I manage to set it till 3mb/s buffer, and latest version of sd tools( with improve and stability of testing speed version), had state my stock sd card (may be class 2-4?) had stable writing speed of 5mb/s (6mb max, but quite uncommon), and with 20mb/s reading speed, which looks more sense than previous diagnose than 3mb/s of writing speed and reading of FREAKING 50 mb/s of speed.
Overall, yes, it match the rumor, it "SLIGHTLY" improve the speed of SD card, but better than nothing ~hey!!!with the moded stock camera i and better writing speed of sd card, I manage get a better FPS on HD recoding, now i can throw my wvga out to my android.

[Q] Quadrant score

Hi there. Why am i getting only about 1000 quadrant score, while everyone getting somewhat like 1500 on the same roms?
Do i have a different hardware or what?
Different roms will get you different results. Gingerbread roms appear to run around 1000+ while Froyo roms run closer to 1300+. Run it a few times and you should get a better score. Quadrant doesn't really matter too much though. What's important is how the phone feels for you not what a graphic tells you.
Thanks for reply, but the problem is that i'm having different results than people on the same rom.
And does the quadrant score affects on how smooth the games are running?
Do you have a lot of apps installed on your internal memory? The "cleaner" the phone is the more optimized. Junk apps will definitely decrease performance. As for running games, quadrant doesn't affect how smooth your game is running but does show performance measures that could be related to efficiencies of your phone. Theoretically, the higher the quadrant score the better your phone will be at running your games.
What file system are you using...quadrant takes your free space for apps in score consideration..
If your using data2sd and have 2gb for internal(ext2,3,4) then quadrant is going to show a better score than those on rfs.

No, i have taken stats from fresh install, also tried different roms, but never got higher than 1000.

No, i am not using data2sd and i guess those people who get higher score than me not using it too.

Oh ok..
But my point was having lesser apps and having more. Internal space will increase the quadrant..
Sent from my GT-I5800 using Tapatalk
Which rom(s) are you using?
FYI - Fresh install of 2.1 will only get you around 500. JIT enabled gets you around 600+, removing additional junk apps will get you 700+. 2.2 Roms will get you over 1000+ easily. Z's Froyo beta 3 got me around 1500+. Others including Gingerbread hover around 900-1300.
I have tried CM7.0.3 J020c and trip's froyo.
In both roms my quadrant is about 1000, but for other people trip's rom giving them about 1400-1500.
I am on wolfbreaks rom..(as per my signature)
The only other thing i do is move all aps to the sd card that can be moved and leave the ones with widgets on my internal memory.
I average about 1450 to 1550 with my best score of 1609.
Run it a few times as well..
On J's rom I run around 900-1200. Never tried running quadrant on Trip's froyo but on his Arc rom I get around 1000-1250. Again, quadrant isn't that big of a deal. Your games will run fine on your phone. Remember, try to have more free internal memory and get rid of junk apps you don't need.
on wolfbreaks rom. i move all apps to the sd card (except widgets)
1300 - 1400
Okay, thank you, guys, quadrant isn't important, but it's kinda wierd that i'm having lower stats than other people.

Its not weird at all. Everyone has different apps and settings which affect benchmarks differently. Higher Quadrant scores don't neccessarily translate to better performance either so why does it matter. Also in order to get reliable scores in quadrant you need to run it twice in a row as the OS will kill apps and adjust as the test runs the first time and the second test is always higher and more consistent.

[Q] chulri´s root and slowdown

hi
sory for my poor english
i root my archos 101IT, 2.4.19+R/W chulri method, everythings is ok, except that i realized a slowdown in internal storage transfer rate.
i didnt remove android kernel to make some tests and to compare when i boot from android and from developer (root)
example
when i boot from android (not root) i took 20seg to load angry birds
when i boot from developer (root) i took 60seg to load angry birds
i did alots benchmarks, not problem with mem, cpu, 2d or 3d
but when bench the internal storage i got 4MB/s in read
when i boot from android (not root) i got 10MB/s
someone know why this happens?
thanxs
Please compare it also with the non-rw version, there is a tiny but maybe important difference implement compared to the +rw version.
bump?
Chulri, I to have a noticeable performance difference after I root. I don't really mind to much bc I'd rather have root. Would you like bench mark results or anything? I have an archos 70 hit.
Let me know.

i never really did any benches before on either stock or rooted.
i used a few different bench apps, all have better results with root EXCEPT for SDcard read. as you can see in the bench 'write' falls around 20-21 on both stock, and rooted.
read was averaging 21-22 on stock and only 6-10 on rooted.
i believe that could cause it to run slower.
what good are better bench results if the system has to wait on reading the disk...
As I asked before, could you please bench the non-rw vs. the +rw root version? Thank you.
I guess I know what's the problem and unfortunately there won't be a quick fix

[Q] What's everyone getting with Quadrant?

I'm debating on taking back my device due to getting such low stock Quadrant scores. Around 850 stock on average.
What's everyone else getting? Am I the only one with such low scores? I appreciate any feedback!
Benchmarks are worthless in general, Quadrant is incredibly worthless because it doesn't break down the scores and is EASILY gamed.
For example, disabling per-file fsync on an ext4 system gains you 600 points or so instantly.
Enabling Stagefright on Samsungs gets you 500-1000 points but breaks media playback.
I'm not talking about using mods at all though. I'm just saying I'm getting half of what I've seen as the average STOCK 1Ghz score for this device. My 800 @ 1Ghz vs. others 1600-ish @ 1GHz. I just want to know if anyone else is getting around my scores (800ish) without mods.
What other devices?
I get about 1300-1400 stock...
Hi,
I just ran it on my (US/rooted) SGP5, and got 947.
I noticed that on the comparison graph, there's Samsung Galaxy S, that had slightly lower number ...
Jim
P.S. FYI, I used Fast Boot, to kill all processes, just before running the Quadrant test. I'm not sure if that affected anything.
BTW, Quadrant gives HEAVY weighting to file I/O scores - so Voodoo Lagfix-enabled devices and native-ext4 ones will smoke RFS devices.

Hi,
Wow! Do you know how you got such scores? What have you done to your device (and what is it)?
As I posted, I just got 947 on my SGP5. It's stock, other than being rooted.
Jim
Entropy,
Your completely missing my point... Here it is again. "My SGP5 is getting around 850~average scores on Quadrant stock, as in, in the state it was when I took it out of the box. Reviewers and other owners of this device are getting much higher quadrant scores with their STOCK devices as well.
When I overclock to 1.3GHz, I get around 1400 average while other SGP5's get around 2k+ at 1.3GHz. I just want to see how many are also experiencing such low scores as I am.
As I said, many of the reviewers online say that the SGP5 gets around 1400-1600 with Quadrant without any modifications or rooting. I get around 850. Please stop with the "Well Quadrant isn't accurate because, if you mod it like this.. you get this", I'll say it again, My. Device. Is. Stock. It's not modified, I didn't do anything to it to boost the score or lower it.
You're missing my point.
Quadrant is unreliable and inconsistent as hell. It can vary by hundreds of points from run to run, it's easily gamed, it will do weird unpredictable things if you look at it the wrong way. Plain and simple, it sucks and its results are utterly and completely worthless.
You ARE benchmarking with the CPU governor set to performance, right? Benchmarks with the governor in play are even more worthless and variable.
I just saw 600 points difference between two runs with the same kernel - 992 once, 1619 the next.
I've gotten consistent bench marking results every time, consistently low, but consistant.... Do you own a SGP and can say this from experience or just because you have a similar Android device? I actually own a SGP5 and haven't seen the "992 once, 1619 next" at all... I've never gotten above 1619 or ever had a jump of more than 100 on the same frequency.
Unless your testing this for yourself on the device in question, please stop once again...
Yes, I own an SGP 5. I unboxed it last night. I actually ran Quadrant again, 1700 the next time around. Just more evidence that it's crappy and meaningless. Benchmarks in general suck, but Quadrant is especially bad. At least Antutu is fairly consistent AND breaks out scores by category.
It's consistent with every other device I've ever owned - run-to-run variances of a few hundred points.
Note that over time, your scores will go down on this device because RFS sucks and becomes slower as it's used, and as I said, I/O performance is weighted HEAVILY.
RFS sucking is a known problem with old Samsungs, that's why Voodoo Lagfix exists.
Returning a device based on Quadrant scores is stupid on an epic scale given what a horrifically worthless and inconsistent benchmark it is...
Around 1300.
Heh, anyways.
What's Voodoo lagfix? And RTS? If you don't mind me asking, not familiar with those two. And so far it performs pretty well @ 1.5GHz with 2000+ quad scores, downloading Antutu now.

RFS is ? File System - it's some special Samsung file system that just kinda sucks.
ext4 is the current standard Android filesystem format, which is MUCH better.
(think of it as being like NTFS vs FAT on a PC)
Voodoo Lagfix is a set of initramfs scripts that automatically convert RFS partitions to ext4, improving read/write performance a lot.
