[Info] Possible fix for I/O issues

Here's a nice thread about a possible solution for I/O issues/bottleneck.The topic is for the Transformer Prime but i guess the devs in here will also found interesting infos.

What issues? I don't experience any issues anymore with the .26 update. I am rooted and unlocked, but I haven't done anything to improve on that part. In .22 it was quite necessary, but ASUS has done a good job with .26.

It's been pretty OK since the update.
And I don't think that moving all data to an external microSD card is such a good idea, I'd rather depend on internal storage, I want my SD to be totally removable.
I'd like to know more about this SQL patch though, but they don't provide much info really.
BTW, there's a typo in your link (no colon after http).

I agree with you, my tablet also work quiet nice with .26 but if you look at the benchmarks the internal storage on our tablet is very slow compared with other old and new devices.
With the above kernel mode we could use external storage for /DATA and /CACHE partition and gain a substantial speed increase.

Ok, so this simply disables fsync, not something I'll be doing anytime soon, at least until the reboot issues are completely solved (I'll be happy with 30 days uptime).
Plus, this is not the greatest idea on a device that had some I/O issues, as it seems sync is even more needed with it.

I don't think the infinity needs an external SD card, it's fast enough and even scoring better than his prime with external SD card.
This is my stock infinity:

That's not really testing the part that fails horribly though. Where our storage performs miserably is random writes. It's around 40-50 IOPS and under 200kB/s. Absolutely ridiculous for a flagship device.
http://forum.xda-developers.com/showpost.php?p=29660695&postcount=25

I'm amazed that folks are happy with the performance on .26. It is better than .22 but performance is still pretty terrible for me compared to my other devices. If you guys use Browser2ram or disable fsync in sqlite you'll realize just how slow this thing still is. In my opinion, buying a fast microSD card(harder than you think for random access) and moving /data and /cache is the best option.

I am noticing pretty slow browsing, pages load terribly slowly. I've tried chrome, Firefox and built in browser. While I agree there has been some improvement, i still get pretty noticeable stutters in ICS.
I mean this tablet has pretty much the best specs on the market...quad core, clocked @ 1.6 and a gig of ram with a substantial internal hd. It would seem to me that there is still a lot of untapped horse power.
That said, early adopters of new technology should often expect some quirks at the beginning, i know i did. Asus has always been great about getting updates out fast for other hardware i have purchased.
I personally feel that with a little patience, we will not only get our fixes and jelly bean, but some great devs making new ROM'S that will really showcase the performance we can expect from this device.

But it's not getting better with the partition moving?! Haven't seen a single Androbench screenshot which shows a big improvement on random writes.

Thats what I misunderstood :silly: So when moving to a fast sd card won't help - maybe a software fix can help there to boost it up :fingers-crossed:

Im not complaining cause i fricking love this tablet but shouldnt these issues been caught during development and testing by Asus? I understand a few small issues may slip through but not something as glaring as some of the I/O problems. Did they not download and install an app while multitasking? lol. Dont get me wrong i am in no way bashing them and would still buy this tablet if i could do it over again.... I'm just not very familiar with the [email protected] process for something like this. Do they just accept a few flaws in order to bring it to market as soon as possible and work hard to push updates?

To be honest this is 1 million dollars question but only Asus (QA department maybe?) can answer. Anyway they already did a good job with the latest update and compared with previous firmwares the tablet is much better and the lag issue many users seems to be gone.
The bad part is the internal memory overall performance because imo that is just poor hardware quality and you don't expect to have such a poor hardware on a high-end device like that.
So if Asus doesn't prove the contrary (but i hope they do) this become a pure hw design flaw and there's not much we could do about it... we will have a nice "bottleneck" on this tablet.

The poor random I/O performance is not limited to the Infinity. The entire line of Transformer tablets is plagued with this issue. Most likely Asus is just making a poor choice when they choose their emmc chips. Part of the problem is that emmc is the same stuff that goes into a sdcard and sdcards are generally designed with fast sequential performance with little regard for IOPs and random performance since most sdcards end up in cameras where most files are 1MB+ in size and you're usually only writing one file at a time.

I think Dees_Troy is correct, we just don't really have a full fledged SSD controller in tablets yet
The controller is more like the first gen ssd controllers that we had for sdd hdds
I guess with software optimization by ordering as much as possible the access and maybe caching more in the normal ram it could be a bit better
But in the end i think it is just pure hardware, we don't have Marvel or Sandforge ssd level controllers yet in tablets, that would make a bit more expensive and power hungry i guess.

The sad part is my laptop HDD (not SSD) has 10 times Infinity's random write and one would expect more from a flash chip.

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.

Well,
I guess I'm going to do the downgrade to ICS .30\root\then try the rootkreeper deal back to Belly Jean.
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.
look at my I/O!

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.

Better than ever
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 Don't know why everyone is having problems with such a decent device.

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.

I think CleanROM 2.2 is the route I'm going to go too...that's if I can figure out how to do it without asking a bunch of dumbs**t questions.
Still reading about it in development.
I'm getting more and more disappointed with this TF700T each time I turn it on lately...
Did really dig it for a while...not anymore

Will i unlock? No...

Possible I/O lagfix (from nexus 7/OneX forums)

http://forum.xda-developers.com/showthread.php?t=2104326
Hi,
Saw this on reddit this morning, as no one's posted it yet I'd just like to offer it up as another potential lag-fixer.
The source of the problem is that internal storage is not properly TRIMmed when needed. You can find lots of information on XDA - http://forum.xda-developers.com/show....php?t=1971852 and http://forum.xda-developers.com/show....php?t=1929021 for example. It is also well-known fact that running fstrim Linux tool from time to time fixes the issue until internal memory runs out of free blocks. Other solutions like mounting with -discard or disabling fsync may be dangerous.
LagFix is a user-friendly implementation of fstrim utility. It allows you to select which partitions to trim (you should leave defaults unless you know what you are doing) and run the process easily.
Please note that fstrim output depends on kernel and device. It works fine unless you see errors. You might see big amounts of bytes, zero amount or repeating amount. All are fine! Read fstrim manual to understand why all these outputs are valid.
It is also advised to reboot your device after the TRIM process so that kernel could reinitialize block data.
App is free and is available in Play Market. Current version is 1.0.
P.S. If your ROM mounts /data with -discard then this app is NOT needed! Mounting with -discard causes brickbug on some devices, so I DO NOT advise using -discard.

I applied it on my rooted, locked tf700 and, well, nothing bad happened. I am on the .25 update, which I feel made overall app-opening a little smoother, so I can't tell if this makes any noticeable difference, but it certainly doesn't seem slower after applying it. The dev says that if you run androbench after applying the fix i/o read should be higher, if anyone could run a few benchmarks of before/after it would be appreciated! I've never really placed much faith in benchmarks so didn't bother doing it myself.
Hope this benefits someone!

I downloaded and installed it. Ran it, rebooted. It did trim, but the jury is still out on whether this actually helps or not. It's too freshly booted to really judge the effects properly, so I'll have it settle in and report back.
It didn't break my 700 -- that's a good thing to start with.

Yeah, I was reluctant to be the first one to try it on an infinity... But it worked out for the better, I think. Now I don't know if the .25 jb update or this is to thank for the better performance. It should hope up till the 4.2 update at least! Quite pleased with the .25 update

Just tried it. Could be my imagination, but my tablet seems snappier.

I am not convinced that it will have any effect: TF700's Hynix eNAND flash is eMMC 4.41 compliant, which does not have DISCARD command, the equivalent of SATA's TRIM command. The DISCARD command is supported in eMMC 4.51 compliant flash but I don't know if the Kingston flash in Nexus 7 is eMMC 4.51 compliant. Even if it does TRIM the TF700, probably it will have little effect if you have alot of free space left as it does not affect the garbage collection significantly. One would hope that TRIM should already be done dynamically within the file management software as it would reduce write amplification factor, hence improve write speed performance?

According to the spec, eMMC 4.41 supports TRIM - what's the difference between TRIM and DISCARD?
I read that eMMC 4.41 also supports "background operation" and "high priority interrupt" - these sound much more interesting related to lag than TRIM. Do you have any idea if these features are already used in the TF700's Linux kernel (or even at all in any kernel)?

faq in op link said:
Which devices are affected?
It is known by now, that Nexus S, Galaxy Nexus, Nexus 7, Nexus 4, Nexus 10 and HTC One X need regular trimming. It is also believed that all pre-ICS devices used different memory and they do NOT need it nor support it. Pre-ICS support will be dropped in version 1.2. Other 4.0+ devices? Well, test it! And report if it really helps - your device will be added to the list.
How to properly test it?
Use AndroBench app before using LagFix and after. You only need micro test. Look for Sequential Write values. Reading from memory is NOT affected, because reading does not involve writting and only writting triggers search party for free memory blocks.

For anyone looking for early confirmation of impact.
I think I'll give this a try. I have some hefty typing lag. I thought one of the first updates had gotten rid of it, but it came back, it was just temporarily relieved by the fresh reboot then. If it does help, it'll probably be a month before I confirm anything, just to avoid giving/having false hope . Thanks for posting op hope it works.
Edit, sorry, just noticed OP already mentioned androbench.
Edit 2: Saw no change in my androbench write speed. Sequential write was something over 5MB/s, random write was .15MB/s both before and after running it, and again after rebooting. lagfix claimed to have trimmed successfully. If anything, it felt more laggy for a while after running it. I'm an OS update or two behind FWIW, just installed Jelly Bean a month or so ago. I like to let everyone else test the updates before I install them. I'll probably run another bench this evening. :shrug:

fsTRIM = AWESOME fix - on CROMI, OCed kernel, fsync disabled
I just download the fsTRIM app and it worked with CROMI, OCed kernel, and fsync disabled. Will seem laggy right after runnng it, just reboot as soon as you do and things will be deffinitely running smoother and slightly faster now. Noticing less keyboard latency even as I type this out. I suggest trying it out.
UPDATE - Seriously try this **** out. Keyboard typing is radically smoother in browser, evernote, and google drive. Less latency between multi touch gestures ive set up in GMD Gesture Control as well. App opening is still instantaneous. Loading big web pages is definitely quicker. Will time boot and other things and update again soon.
Update - Opening large files and youtube is faster. large pdfs load faster. everything is really....snappy, and.....smooth.....best of both worlds. things were already pretty snappy and smooth with CROMI, didnt think they could get better but it has. I time everything as well to compare. I could barely time it after this fix as everything is basically instantaneous. Havent tried writing/moving large files on internal storage yet, will test soon, this is distracting me from my homework too much lol.

It works for me I can now download files and move them without having my tablet unusable until it's done.

What do you have on your device? Why is it running out of memory every 2 minutes? Any way, I see quite a bit difference in performance but your warranty is void because of an unlock of your bootloader. If I know that there is nothing wrong with the hardwares, I will go with the custom rom. It is just my two cents..

stutter and lag when scolling?
Slow switching between apps?
Browser not responding?
All very "normal" for stock, unfortunately.
I got fed up enough to unlock and flash CROMI (way back then...). "Major" doesn't even begin to describe the difference it made. It's like getting new device. Now running CROMi-X and I absolutely love this tablet now. It's the best tech purchase I ever made (after some improvements thanks to the dev community).

Make sure you are on the latest bootloader, make sure you don't have a slow sdcard in, do a full wipe of /data in the latest TWRP, flash CROMi-X or CROMBi-kk and profit

First, THANKS!!! for answer fast .
humm, i will try to don't use the sdcard, now i have Clokworkmod v6.0.4.4 installed and i will install the new CROMBi-kk (i always do a full wipe).
Thanks again.
EDIT:
I hate this tablet, full wipe, no sdcard, new crombi-kk, no apps, open de stock browser tap the navigator bar, try to write "www" (push all this leters in the keyboard), the tablet freeze 2-3 seconds and wrote just one "w".
In the first start (start configuration options) the tablet micro-freeze a lot.
I'm the only one to see that? i have shame to sell this tablet...

What's a " full wipe" for you?

It is not just you.
And yes it might be the worst tablet ever for that price.
I had the same issue and got it repaired, helped quite a lot to get a new mainboard.
Now it is at least usable.
Still can't compare it to my Nexus4 but at least I can browse the web

To be fair, I know this is a tough pill to swallow, but you should readjust your expectation a bit. By 2014's standard, any Tegra 3 tablets should be considered entry-level devices, so if you are expecting Nexus-like performance with 60 fps UI all the time, you will be sorely disappointed, regardless of ROMs you are on, simply because the tf700 has really slow internal storage. Having said that, running custom ROMs does make the tablet perform much better than stock and much more usable. You should just follow all the advice above and try all the ROMs/tweaks above to see if the performance of the tablet meets your expectation. If it doesn't, just sell it for a better device. The tf700 right now should be really cheap after all, I doubt that it cost you much to get your current tf700.

My tf101 just broke, really was good to me.
Saw this for $200, is it worth it?
Any other suggestions in this price range?
Gotta be 10".
I know it's old but that's OK. Gotta be faster than the 101 right?
I want to root for sure...
Thanks...

Is that including the dock? If it is, I'd say yeah - it's worth it.
If just the tablet - Newegg, Tiger Direct have the TF701 for $299
That's just 30% more for a much better tablet.

To be honest, I remember seeing quite a few people claiming that the tf101 is actually faster than the tf700 (stock vs stock comparison of course), in terms of UI rendering and general smoothness. I am sure if you Google around, you will find a few threads claiming the same thing.

Thanks

Sorry for the late recommendation, but you could try C-romiX rom with Data2SD modification. This improves the performance of the tf700 a lot! night and day difference.

OK

When i use Data2SD, all data go to the external microsd? if yes, my microsd is a HC 4, is too slow?
Thanks, Saludos!

Class 4 is probably too slow but some class 4 cards are quick! My recommendation is stay with a uhs-1 class 10 card if you can.
With data2sd the /data partition now resides and runs off the sd card

I can speak for Cromi X 5.4 (which is the official update released by asus but modified by sdbags) its based on android 4.2. It runs great on the tf700 with data2sd mod. Web browsing and download speeds were greatly improved using data2sd. You wont regret doing this. Remember that with this modification, all data will be stored on the SD card you are using (all pictures, music, videos, games, all will go here) so make sure you have a fast sd card with sufficient space. Internal memory will be used only as storage, so if you ran out of space on you external sdcard, you can trasnfer file to internal storage (you can a file manager to do this, I use ESexplorer or root explorer)

thanks
Guys, I buy a class 10 U-1 microsd, and yes, works better, but slow anyway. (CrombiKK + Data2SD)
Probably wrong wipes and the huge amounts of roms tested, installations and etc, are the problem.
Some Asks
- Rom2SD or Data2SD?
- How can i make a perfect installation? (some some tests left trash)
Thanks for all.

The slowest tablet I've ever used
[Deleted]

me too.
mine is a refurb. 5 second lags at least before it recognizes anything. strangely it flies in twrp mode.
my benchmark scores are around 5000 with cromi 5.4 where it should be 7500 from what I've seen.
always wiped when I flash.
I want to bin this thing.
I have a Toshiba thrive which kills this and my kindle hd fire creams them both. I really don't understand what the problem is.
ideas??

Hi, my 0,02$. After trial and error, and when I say trial, it's like, I've tryed every ROM and every tweak possible, I've come to a tweak combination that gives me pretty much reasonable performance on my TF700.
After full wipe, and low format the data partition, installed the Zombi-X KK ROM, with fsync and data journaling disabled, browser to RAM enabled. Then, installed the app "Resolution Changer" to adjust the screen resolution to 1280x800 at 160DPI (I know that I could have done that on the ROM setup, but I prefer to do it on the go inside the system, so I can try different combinations, and get back to 1080p resolution with ease, if I want it). I also use the fstrim app, with the memory triming scheduled 3 times a week. Et voilà! It's far from a perfect tablet experience (as it should be, for the its price) but it is much faster and better than stock ROM by far!
