Terrible I/O - TF700t

Got it for 4 days now. Terrible speeds when downloading content not because of the WiFi but the storage.
It is very difficult to use any torrent client as the whole tablet stalls. Very difficult to install big games as MC3.
Tried both default and rooted, changed the IO scheduler - no big difference. Copying files from PC takes a LOT of time as well. Seq read 17 MB/s , seq write 4 MB/s ...
The really bad thing is that the whole tablet becomes unusable - even the mouse pointer does not work when there is a long IO operation going on.
Any thoughts since the problem is not solved for the whole Transformer family?

Try plugging a USB disk to your dock or use the SD card. Works faster for me.

Some benchmarks ..

I'm getting similar results in the benchmarks mostly, so let's consider it a standard for the Infinity
I would be worried, however, about 0.5 MB/ write speed! If you get it constantly and even with sio scheduler, I would definitely consider having the device replaced on warranty terms. Something like 10x that speed could be considered a (lower end of) standard on TF700.

Try different (benchmarking) programs however. Androbench has been said to give false results on some devices.
I've done a simple test using SD Card Tester now (500MB test file), in balanced mode it's somewhere near 8 MB/s write* and 18MB/s read for the internal storage on average, and 5 MB/s W + 17 MB/s R for the microSD card (AFAIR the best results were for the full-size SD card, something about 15/30, but I'm without the dock at the very moment).
Hope this helps.
* it starts with 17, but then decreases because of the numerous lags (happening all the time when writing bigger files on the Infinity, sadly)

Ah, and don't compare it to phones
See http://www.androidpolice.com/2012/0...hmark-11-modern-devices-compared-in-13-tests/ as reference point (originally posted by shinzz).

Noticed this major problem as well.
Basically it can be triggered by uploading lots of files using wifi to the tf700 running airdroid. Then using the stock music player it will lag like hell...
Then again, if you run airdroid on another android device and the launch a internet browser (either stock or dolphin) connect to that device running airdroid, basically becomes totally slow but this maybe caused by the browser itself....
Not to mention the kernel constantly clocks the processor in range 100MHz - 500GHz this further, push I/O to even more constrained.

The CPU speeds can be changed by using different CPU governor. In my opinion the default "interactive" governor actually performs pretty well (performance/battery life).

It has been referenced in several other threads that, indeed, the I/O of the TF700T is absolutely abysmal. That 500 kB/s is really, really low, though. I have the lags all the time, and several movies files have stopped playing many times during my (long) commute viewing tries... I really hope that custom ROMs can better this by a fair margin. though I don't know to what extent it has been the case with the Prime's similar issues. Gotta go and nose around in the AndroWook thread a bit...

Full-size SD card in the dock: 20 MB/s write (worth noticing it actually started with 45 MB/s, which is the card's limit, so the lags take in again), 12 MB/s read, same test, pretty weird, as I got 30 MB/s read there before.
With 2GB file I got 15-16 MB/s write & 10 MB/s read on SD, not sure why reading speed dropped that much, but I think I tested it on NTFS a few days before and now it's re-formatted to FAT32.
Edit: So I've just tried the last test with NTFS-formatted SD card and it showed 16/10, so no clue why it dropped this much since my earlier test a few days ago!

I didn't format my card as it came pre-formatted. I'm going to empty it and format it in device and see if that helps. (The card that has been in my SGS2 for about a year performs very badly.... no, let me rephrase that... doesn't perform at all in the TF700T. Let's see if we can get it to shine a bit.

Don't you think somehow caching is involved as the file copying goes steady and then stalls and seems to stop for a whileand then goes again. As if a buffer fills in and one has to wait for it to be persisted in the storage?

The trouble is that during this the tablet is totally unresponsive.... At least mine ....the problem is not with the speed but the fact that the tablet is overwhelmed with IO and one cannot do anything else....

Yes, I do think it has to do with (shared?) caching, and yes, the most frustrating aspect of it all is that the damn thing just hangs up sometimes.

Mine doesn't lag when downloading or anything... but updates will fix the many small problems

I have two questions
1) Why isn't ASUS bombarding us with promises that they are looking into it, in an attempt to retain market share?
2) What are the chances of this being hardware related, and thus never getting fixed?

1) They're probably quite busy with the Nexus at the moment. Furthermore, seeing that the Prime suffers from very much alike I/O issues that haven't been fixed as far as I have been able to find out, they probably don't care as much as we would like.
2) No one can tell at the moment, but let's keep our fingers crossed that it is software-related and thus fixable by either ASUS -- eventually -- or by custom ROMs. It seems that some custom ROMs for the Prime have significantly improved on its I/O (e.g., AndroWook).

but can a software update fix the camera clicking issue. i would guess that has to do with the hardware.

Possible Solution
If the I/O errors are linked to the minfree then I think the v6 SuperCharger could help. I have posted a link in the Infinity Development thread since it can also be embedded into a ROM.

On the SGS2, the standard camera app makes the shutter sound as well. That has been modded out by several developers over there, so I guess it is possible.

Could anyone please follow ganja's lead as well and report back in here? Either it's wishful thinking or it does indeed help quite a bit. I suspect I'm just going crazy, since I did get a few errors in the script's execution -- I have been unable to correct all of them, but maybe some people more knowledgeable than me can see if this actually works (and what the fixes, if at all necessary would be).
The installation tutorial referenced in the thread ganja linked to in his other post is a nice guide to have. Again, seeking in video and such seems to be a lot snappier (almost instantly). Opening QuickPic (a gallery app) in a folder with HD wallpapers is really fast (I had never opened that particular folder before, so it had to render all thumbnails).
I'm not sure if I'm just losing my mind and seeing ghosts. I'll hold off on that judgment for now.
Thanks, ganja!

http://en.wikipedia.org/wiki/Linux_kernel#History
Now here's the catch why would Asus uses a such old kernel revision while there are latest and current and stable versions available.
Since 2.6 has been a deprecated branch and it is no longer being developed why has Asus create a hassle for its own brand name, why would Asus put a old kernel which the base code was release in Dec/2003. And to quote from wiki...
17 December 2003 - Linux 2.6.0 was released (5,929,913 lines of code).

Why would Asus created a Tablet which features current H/W designs and still uses the old 2.6 deprecated / unsupported kernel???!
This is what puzzles me.
If you do a bit of research you will find this email from Linus himself stating that the old branch is ___in THE PAST___.
Quote again...
As of 2012, the Linux 3.2 release had 14,998,651 lines of code

This email was back in 2011 ...
https://lkml.org/lkml/2011/7/21/455
So what has Asus being doing was designing the HW along with the Linux kernel through out the past several years and came up with this solution ?? Would rather amazes its customers.
Anyways what I'm trying to get the message across is that Asus should have being kept up with technology and bit of quality control and the design.
Edit:
Also this kernel would be insecure and should be exploitable...
Nevertheless a device based on 2.6 would be suspect-able to security risks.

Is this tablet really this slow and buggy? Worth rooting?

I just bought this device as a toy and a test as a computer tablet. I found it to be slow and buggy. I do notice that in browsing heavy pages like the real facebook page it IS faster than my Galaxy Note 1 but in almost everything else, the Note is faster and snappier. I have disabled lots of apps, resett it, no change. So my question, I guess this one is really worth rooting and installing a good rom Im used to the Cyanogen to my phones, is Cyanogen working good for this tablet?
Im still marveled by the quality of the screen, I dont think I ever have seen such a good screen! If I just now could get it working somewhat near as good as my Note 1 I will be a happy panda
Thanx in advance peeps

My experience is that it is NOT slow and buggy.
I could compare it with an iPad3 last week and I think they are very close.
You can't compare it with a note because due to the much higher resolution the gpu has to do so much more computing. That is why the nexus7 is faster than the tf700 due to it's smaller screen AND resolution

I'm on stock rom with browser2ram and force2gpu enabled. My table is very fast. Just remember before you flash a new rom, just do factory reset(data wipe 3 times). Also root is good (allow you to install rooted app like Titinium backup, SetcPU etc..), but don't unlock unless absolutely necessary (void your warranty), or you have time or like to play with custom rom.

Ok, sounds like I will root it then and try to tweak it, Im not satisfied with the speed with it sofar. Its seems stable now after I resetted it, before the reset, it crasched 2-10 times a day. My idea was that since the GPU and CPU is older in the Note, The Tegra 3 would be able to handle the FullHD resolution but it doesnt seem to .. I definatly want a ROM without the garbage crap
I plan to use it to write alot on, can you recommend a good office app? Or a browser that google docs work good with
Is games running good for you?? The new demanding ones I tried before resetting was really slow and laggy.
Thanx for the replys, I hope I get this baby running smoother

Yes, all games, videos, pictures, and documents and apps are function normally. There are 3 most popular office apps:
1. Documents to go (this can view google docs also. Paid version only)
2. Kingsoft office
3. Polaris office (currently polaris has a bug with fonts).
My stock browser can view google docs fine. I think stock browser is the best in my opinion (have tried boat, chrome, mozilla etc...)

The Infinity's performance is not CPU bound and is not due to the higher res. It's I/O limited. The CPU is plenty fast enough. As soon as the memory config requires the system to start hitting the /sdcard memory, the system will be subject to random stuttering/pausing because the sdcard memory is the cheapest, slowest, crappiest flash RAM ASUS could find.
This is why stuff like browser2ram is seen as a huge boost for people that do a lot of browsing and it is also why the stuttering varies from user to user/session to session since the RAM situation in the system varies from config to config and moment to moment during use. Some users who's config has a lot of free DRAM and do not frequently use stuff that hits the sdcard partition hard, see almost no performance issues with the tablet.

I really don't want to go thru all this, but if I want to keep chipping away trying to find a better Android experience then so be it.
Pain in the ass...

Thanx for the info! That was my biggest thoughts about the Infinity, "is the RAM enough?" and it isnt but then Ill just have to multitask less and try to tweak it. And perhaps dont install multipicture wallpaper.. but thats one of the things that I love about my Note
buhoitr: thanx for the suggestions, Ill try them and see
What rom would you suggest for getting the most out of the Infinity?

Hmmm, I've found mine to be quick and virtually bug-free, but then again I didn't buy it as a toy.

A little tweaking and I wouldn't call it slow. Even stock its a solid piece of equipment.
Apply data2sd mod built for CleanROM 2 after installing the ROM. You'll need a fast sd card.
Research the threads. The blob for data2sd for that ROM was just posted today.

I own both the Infinity and the Acer a700 and after the a700 got JB earlier today, I will say that the Infinity lags more than the a700 (and I was very happy with the Infinity). Colour me shocked.

The only time I really ever experience any lag or sluggishness is when browsing. I will be rooting once there is a method discovered for Jelly Bean on the Infinity. I'd really like to give browser2ram a shot. I've heard it does wonders for browsing.

Before i say thing, I will list the important things about my tablet - C7 model, Has been repaired for speaker issues & Jelly bean 4.1.1. I'd say TF700T is a powerful device, It lacks the software for it. I use to notice quiet a bit of lag on ICS but after upgraded to Jelly bean, It's faster than ever! I would even compare it to iPad 3:laugh: I'm running Stock Jelly bean with a bit of removing apps here and there.

I you guys would read the Development section (read the newer threads, please) you would see that CleanROM2.2 has pretty much completely eliminated the lag and i/o issues. It's reason enough to root and unlock. This tablet is a beast when it is allowed to begin to reach its full potential.

[Q] To Data2SD or not to Data2SD...

I have read a lot of the I/O bottleneck problems about the TF700, and using Data2SD is the best alternative the development has to offer to solve this.
The question I have of concern is whether I should do this now or later? I have gotten myself a new replacement of the TF700, and successfully rooted, unlocked, and Inherited the Clean ROM Inheritance. Doing this is something I'm not sure I want to do now considering the internal is still running pretty okay right now.
If I do wait it out and then decide to do this, would it be too late? I'm just wondering would I get optimal speed of performance once utilize the Data2SD after the degradation of the internal?
Thanks.

Personally I think CROMI with browser2ram resolves most io problems.

No, you can switch to it whenever you want in the future without any restrictions.

Sbdags and _that are much, much more knowledgeable than teeny me, but I also think CROMI currently solves most problems that the 700 had at launch time. Some I/O issue will remain under the surface, but it's been fair sailing so far for me (admittedly, I did not have that much issue with it anyway ).
I tried getting data2sd to work -- curiosity finally won over cautiousness -- but I could not, for the love of all that is holy, get it work properly, at least not in the first six tries. Minitool ruined my microSD card, although Gparted was able to recover it. <phew> I then proceeded to install data2sd. Although apparently correctly installed, I noticed very little benefit.
As I said, it could be speculated that my microSD card is screwy (I'm shopping around for a new Sandisk 32 or 64 GB Class 10), and I would have nothing to base a denial on. A better card might have shown a tremendous degree of improvement, making me use my 700 so intensely that I'd drain all available power from the one nuclear power station in the Netherlands, making it melt-down all the way to China, making them retaliate, thus ending the world a few days late.
I doubt the latter, however, and will stick with CROMI as it is. Just great.

I use my tabby for the internet. Mail, youtube, browsing. Clean Rom and browser2ram has eliminated my io troubles. In fact, i'm running CR 2.72 and haven't bothered to upgrade because i just don't feel the need.
Plenty of folks have had luck with data2sd. I was not one of them. With two different cards, i had similiar results. It wouldn't run reliably for more than an hour.

I still get lag when downloading apps in particular when its trying to install after it downloads. Also transition lag in opening apps is still there as well as scrolling though the recent app list but mainly when youre in the home screen or again while apps are installing. Games still lag as well from time to time. But games do open faster.
The only advantage I see with the data2sd is app opens slightly faster like heavy HD games. IMO data2sd is not a must if you're already running CROMI as it doesn't make a lot of difference.

I felt pretty newbie asking about what CROMI is when I didn't realize it stands for Clean ROM Inheritance. Not only that, but I also have Browser2RAM installed not too long ago.
Anyway, I really don't have any HD Games to boot into my tablet yet since I don't see a lot of choices offered in my interest. If doing data2sd really isn't of importance, then I guess my question is resolved. Thanks guys!

Seeder by lambgx02

As we are too well aware, the A700 isn't the quickest tablet around. A problem fixed quite largely by using the Cool One firmware and the Tegra OC kernel. But there is something else you could try; Seeder which has recently garnered quite some attention.

I couldn't notice too much difference in my short time using it. Launching and using Chrome might be a little quicker and Maps may be a little faster but some have reported large gains with it, so why not give it a shot? nb. It requires root. And do let us know here and in the original thread how its goes for you.
ps. Seeder seems to turn itself off after resetting the device so be sure to check if it is turned on.

I'm currently running IconiaN 2.4 and I installed Seeder a little while ago via CWM and tried a few things. Maps is definitely faster like most have said. I played a couple games and I found Edge and Edge Extended to be roughly the same, Pitfall is the same, Beach Buggy Blitz is the same, and so is Sword and Sworcery. TigerArcade (a Mame type emulator) runs WAAAY better now, not sure why, but it might be because the games I'm playing use a caching system to load on the emulator. I'm going to try Need for Speed Most Wanted as that ran like garbage last time I played it and I hope it may be slightly better this time around. Non gaming apps: Youtube is lot more responsive than it used to be, ES File Explorer seems faster as well, not 100% sure, Android Browser and Chrome both seem roughly the same but haven't done extensive testing. Lastly unlocking and hitting home from within apps is definitely smoother and faster like others have been saying.
My recommendation is to go ahead and give it a go as it seems like its worth it, plus if there are updates to it that make it any better you can just CWM those right over the current version with no need to wipe cache or data at all.:cyclops:

Thanks for recommending this. Will try.

why don't I have Zram/Zswap anymore?

It's been a while since I managed this stuff myself so I'm foggy on how to troubleshoot, but something along the lines of I don't have an /etc/fstab or it's empty so swapon is failing.
previously used FauxClock to manage this, unsure why it's not working like it used to.

well, to answer the question in the title.. because its pointless. zram/zswap is good for our old devices(like g1 or old school droid), with low ram. as thats what you are using the zram/zswap for, to increase ram. the nexus 5 has 2gb ram, i bet you will never run low on ram with a nexus 5. and if you think its a benefit to the nexus 5, then you are living in a placebo.
what happened to yours, i have no idea.

can you help me get it back?
I feel like a FauxClock update broke it.
What it was actually doing was a bit more complicated, virtualizing the diskspace (compressed, too) as a buffer layer on top of the flash. This improved random read and especially random write performance which helped with multitasking a LOT as resume from suspend in the app lifecycle was resuming from RAM, not from flash. This meant less hitching/FPS drops when bringing up android recents, as well as during animation/draws when switching to the other app
This is the only reason I want it. Simply as swap space, yes not necessary

that sounds what disabling fsync would do, help with random read and write. have you tried just disabling fsync? anyways, its your kernel that will have the zram feature, reflash it. if you have flashed/updated your rom, the kernel should be reflashed.

no fsync is totes different
current guess is no init.d script for the zram because restored fauxclock from titanium and enable/disable only modifies the script, relying on the script existing in the first place, and it doesn't because I didn't manually install it myself. Uninstalling and reinstalling fauxclock doesn't work though, it's like certain settings persist somewhere. It's always been a bit goofy like that, and I don't feel like wiping and installing just for the ZRAM at this moment. Currently waiting on someone to post their zram init.d script, or if anyone here sees this and wouldn't mind uploading it, much obliged.
another question: how can I low-level format the phone? IE not just wiping the partition, but actually checking for bad blocks and cutting them out of the flash table. I have another phone that I think needs that, but all the CWM and TWRP recoveries seem to just do wiping not complete formats.

init tasks are somewhere besides /etc/init.d now it looks like
if anyone else needs it, flashing completely stock image straight from google and then rooting got me what I needed. Unsure why the "stock rooted" zips people provided weren't good enough. oh well
