I/O & Disk Read/Write issues are caused by non-efficient software for those things.

I have some promising things i found out. I have more proof to show this disk I/O issue on prime is really a software issue that Asus could easily address if brought to their attention. which i will shortly after gathering info together. I came across a head to head battle of Prime vs. Acer510. It ended up a tie. that's really not my point of this though. The focus is memory & I/O differences. The performance battle of various benchmarks showed the Prime crushing the Acer510, by alot. Especially in the I/O scores. For example:

Quadrant: Overall MEM I/O

Acer510- 3755 3194 1042

Prime- 4175 2945 3928

Ok, in memory, The Acer edges out this prime but the difference is only 249 points. The bigger difference comes from where prime shines, at least in this benchmark, in I/O score. The Prime soars ahead of the Acer510 by 2,886 points difference.

Now just going based off scores, the prime I/O and disk read write speeds should be alot faster, right? well the site tested this in the real world. The test was both downloaded an app from the marketplace at the same time. The app was a game called Farmville Invasion. Once both started at the same exact time, The Acer510 finished downloading it a full 20 secs. faster than prime. same scenario in other things like google play music. the acer had it up and ready to run like 5secs. faster than prime.

The sites exact quote was " Of course, that's not to say the TF201 is slow by any means, just that the A510 does things more efficiently, despite being at a disadvantage on paper." Doing things more efficiently means software optimization since specs are almost virtually the same. both use ddr2 RAM and both have the same tegra3(although prime tegra3 seemed to score alot higher overall across benchmarks). the only main difference here is Acer firmware vs. Asus firmware. So Asus could easily address this software issue that's causing the real world slower I/O. something in the firmware is not coded right or something. Or needs to be done more efficiently. Because by the scores, Prime should be alot faster in real world I/O & disk read/write speeds. I don't know if the acer suffers from slowdowns while an app from the market is downloading. So Asus needs to work with Nvidia to address this and push a fix once n all for this. This has never really been a major issue brought up to them before. If i can help it, ill make sure they know about it.

Any thoughts or possible other causes?

@Rubuen That developer finished the custom build.prop that i told you about earlier. i have it but haven't tried it yet. i hear so many horror stories about people editing their build prop and bricking their prime. Only difference with this one is a well known developer made it so its more likely to work..lol
[Asus  Eee Pad Transformer Prime] RubenRybnik:
Nice write up, I've read others like it pointing to software. All in all that's good new for us. What has be worried is that Asus hasn't said anything about it. I can't believe they don't know about this, how would that be possible? I'm sure someone on their R&D team, or PR team, etc... have come across forums and threads like this, so why don't they come out and acknowledge it. My fear is that they know about it, and since they have the Infinity on the way, their going to throw us to the wind. The only hope here is that the Infinity and the Prime have similiar hardware and the fixes will translate to both devices. I don't know maybe they'll pull through and prove me wrong, would just like a little love from them, and a heads up to us all stating their working on it.

On other news, if you work up to trying out the build.prop let me know how it goes ;)
[Asus  Eee Pad Transformer Prime] demandarin:
I'm running the custom build prop now that the developer, I mentioned earlier, made for me using my original build prop. Added alot of lines for performance and battery improvement in there & moddifed some existing ones. so far so good. I can't even describe how much faster n fluid the scrolling in UI and browser is now. My prime was good n fast before but now its like super fluid..lol. there's a bunch of other tweaks in there also like increased JPEG quality, wifi connects faster, wifi scan decreased for improved battery life, dalvik VM cache increased. Basically general performance increases, faster scrolling, image quality improved, better deep sleep, wifi adjusted for faster connections and better battery life. tegra specific tweaks also. Too much to list..lol

I found several threads listing all the build prop tweaks and what they do. so I can cross reference what's in my new one with the ones available. so I know what they all do, which is a good thing. I was worried at first of bricking my prime trying it but its running great so far(knock on wood). Battery seems to drain alot slower now but will really test it later with a fresh full battery & see how long it lasts.

I think this thread will go a long way to letting asus know of the issue. There was many threads about gps issues and look what they did. For having this problem since the begining you would think this thread would be 100+ pages but it was only created recently.
[Asus  Eee Pad Transformer Prime] riyatch:
i think it was only recently because we had hope that it would improve with the past updates but actually it just seems to be getting worse with the updates. at least that has been my experience. such a shame because when the prime is running smoothly, its a joy to use.....too bad it just keeps getting worse as time goes on.
[Asus  Eee Pad Transformer Prime] sectachrome:
I am starting to consider getting an iPad because of this problem and the laggy/buggy browser in general. Fix this already, its absolutely ridiculous.
[Asus  Eee Pad Transformer Prime] Rytkonen:
Hopefully this gets fixed in the upcoming update which will be released soon. Otherwise I'll probably sell this when I get my SGS3.
[Asus  Eee Pad Transformer Prime] budtz:
I really like Android. I love my Galaxy Nexus - its so fast. I have been a very happy user of Asus products for many years. My Asus M6N laptop from 2004 is still going strong and the best investment I ever made.

But this TFP browser issue is unacceptable. It's really, for me any how, the main purpose of a tablet. To sit or lie on my couch and browse the web. I am so annoyed by the fact that this experience is so perfect on my parents ipad1/2/3. I really dislike Apple as a company, but is there really any alternative to biting the Apple and getting an ipad until someone can manage to turn a Tegra 3 quadcore "powerhouse" to something that can actually browse the web??

Can someone make a direct ipad2/tfp browsing experience comparison video and post it on the web somewhere?

Asus, are you listening?

[Asus  Eee Pad Transformer Prime] julien.me:
Well said monsieur.
[Asus  Eee Pad Transformer Prime] tangiers:
+1. I replaced my Xoom for this and yet I find this behaving as if it two steps backward to the Xoom. Browsing is intolerable and many other tasks just seem to lock up. My experience of the Tegra processor has been a very negative one.
[Asus  Eee Pad Transformer Prime] indie13:
The worst thing is that the TF101 is fine or at least 1000 times better at web browsing! I so wish i'd not "upgraded" to the TF201. I wonder if its tegra 3 related?

I so want to love the prime but i'm failing as the issues keep getting in the way of doing what what you want to do with it (and what it is designed to do, i.e.

browse!)
[Asus  Eee Pad Transformer Prime] Rytkonen:
I dont think so, because international One X does not lock up like this. It is probably just bad software. I was surprised how little attention this issue has got versus gps/wifi issues.
[Asus  Eee Pad Transformer Prime] RubenRybnik:
So if your main issue is with browsing only, you should know Asus is pursuing this and is already beta testing kernels to fix. I'd expect to see something soon from them with fixes, how good the fixes are I can't say.

That being said, I'm more perturbed my the overall slow disk IO then by the browsing issue in particular. Why does it sometimes 10x longer to uninstall an app on the Prime than my SGSII? Once that's fixed I'll be happy :)
[Asus  Eee Pad Transformer Prime] budtz:
True that. And if it really is due to abysmal disk IO I can't see software fix for it. I'm eagerly await the upcoming update - if this doesn't fix the browser ANRs I'm selling my TFP.
[Asus  Eee Pad Transformer Prime] RubenRybnik:
disk IO could certainly be a firmware issue, and I'm really hoping it is. I was like you, almost at the point of selling it. But running AOKP, adding some build.prop tweaks and using the V6SuperCharger script( check forums if you don't know ) really seems to help.

A good test that points to this being disk IO related. I use iSyncr Wifi to sync my iTunes( yes I know, I have no more Apple products, but haven't migrated to media monkey or anything yet ) playlists to the Prime. If I kick off a sync and let it run, while it's trying to sync songs, by Prime is pretty much useless, laggy, slow, ANRs in system, etc... If I do the same on my SGSII everything is perfectly fine while iSyncr works in the background.

This can also be seen when unzipping large files in the background, in case anyone was going to call me out on not eliminating anything with Wifi ;)
[Asus  Eee Pad Transformer Prime] budtz:
I have indeed been tempted to root my TFP to alleviate the symptoms. But then, I don't want to void my warranty to solve a problem that I suspect might be caused by lousy hardware... it's a bit of a predicament.

Yeah, I've noticed slow unzipping, slow application installation etc... compared to my Galaxy Nexus.
[Asus  Eee Pad Transformer Prime] banderos19:
Ive got a feeling that all our prime issues are software related.

Ive got virtuous prime stock kernel running, have had it for a while now, and have not changed anything in that respect, apart from installs of various apps, and patches like the agps patch and ez overclock

Now, i never did any thorough, and im mean THOROUGH tests when i first installed the virtuouse rom, but im pretty sure i would have noted the problems that i seem to be having now, im pretty sure i would have taken note, i.e. the odd reboot when using a browser, browser not loading pages and flash videos not loading everytime

Its a bit weird to be honest, since i havent changed anything major rom/kernel wise, so unless i have a stray app, which is unlikely, considering the chances that all us prime users have downloaded the exact same app which is causing this issue is unlikely.

Now a patch or a tweak, such as ez overclock or agps patch, would be a more likely culprit, but perhaps there is another issue, considering some prime users who are locked and using official stock rom and stock kernel obviously

Which leads me to something another user here said, and sorry i cant give creds to him, but for the life of me i cant remember where i read it

Basically, he was having similar issues with his rooted htc phone, similar enough for him to come on the forum and mention it at least, and aparently the devs working on it, if i remember rightly, found the issue to be the official frameworks on the official firmware, something about the frameworks "sale by date" running out, and im assuming needing to be renewed.

Now this to me would explain the reason why my Virtuous rom (and official roms and any other rom based on the official roms), seemed to be fine and dandy when first installed, but is now acting up, perhaps there was a "timed" problem which occured when certain frameworks all ran out at the same time.

Now this is all conjecture on my part, and frankly, im a noob with these things but it could be an avenue to pursue perhaps, then again if this is indeed the issue its likely asus is aware of it, and it might well be fixed already in their upcoming firmware.

I guess time will tell
[Asus  Eee Pad Transformer Prime] MRCANNADY:
From what i was told, the disk-write issues have also been addressed with the new update. The issue is how the system prioritizes it's resources when for example, using the browser and downloading songs in the background. The Prime is more than capable of multitasking just like the SGII or the HTC X, it's just the way the code was written for the device which oddly makes the Prime issue all CPU resources to the *bigger* job (e.g., downloads) and thus making the tablet lag when doing other things. i can not confirm that this issue has been fixed with 100% certainty, but if it's true than the new update will better handle thread priorities. We should also see much better speeds in browsing, game crashes have also reportedly been fixed (prior kernel issue) among other tweaks to the system, which includes improved battery life. We shall see sometime this week though :)

YOu won't lose warranty because of root!

You only lose your warranty if you unlock, you can root your device without voiding your warranty. There is a distinction between these terms. Google is your friend and so are the XDA forums. Peace, V :rolleyes:
[Asus  Eee Pad Transformer Prime] deathmaxster:
I have the same identical issue, with any browser and using other apps.

I have the same issue also when copy file or download some app from Play Store! Occasionally Asus Task manager crashes!!
[Asus  Eee Pad Transformer Prime] vatastala:
Exactly, I can confirm that the issue happens also after play store app download, during app installation the system is not available until installation finish.
[Asus  Eee Pad Transformer Prime] subomai:
I'm having the same problem with my prime and it is not just with the browser. Happens randoms with any app although happens more frequently with any of the browsers.

Seems to be tied to loading media rich pages which may be stressing the disk io

I've also tried copying files from the SD card on the dock to the internal storage and it slows things to a halt. Definitely seems disk write speed related. Also hoping the next FW upgrade can resolve if it is indeed a software issue.
[Asus  Eee Pad Transformer Prime] RubenRybnik:
This is exactly my point, the thread should be renamed or a new one created as I hope Asus isn't just thinking this is a browser issue. I send a message to Gary after he sent me the newest beta kernel( haven't tried the beta kernel as I haven't had the time to flash stock back on the Prime ) but never heard back from him. -Really- hoping Asus is approaching the issue the correct way.
[Asus  Eee Pad Transformer Prime] Smando:
same problem here Browser not responding with stock ROM and with Cyanogen..
[Asus  Eee Pad Transformer Prime] budtz:
If only I could get a TFP with a Galaxy Nexus inside....

Has anyone tried getting an RMA based on the terrible browser/IO performance?
[Asus  Eee Pad Transformer Prime] Tempie007:
same problems here ... realy slow io performance and sdcard writes lock up the system..

my girfriends galaxy s2 installs - and removes applications 10 times faster than the prime ....

not rom-related, aopk, gummy, stock; all have this problem!
[Asus  Eee Pad Transformer Prime] Rytkonen:
That does not sound very good.
[Asus  Eee Pad Transformer Prime] Peter Galbavy:
I'm pretty confident that this problem, and many others I am seeing, are related to the speed of the internal SD/flash and in this case browser caching. Trying to copy music to the internal SD (/mnt/sdcard/Music) runs as an stop-start-stop-start rate of some stupidly slow rate, especially when compared to my class 10 microSD card.

I wonder of this is a device driver issue rather than a hardware issue though?
[Asus  Eee Pad Transformer Prime] mdeblaz:
I have to agree with where this topic has gone. While typing this extremely slowly due to unbearable lag, i am downladong a large file for Modern Combat 3 (just noticed its available now for the prime). This isnt just a browser problem but an entire system issue... everything is lagging right now for no other reason than the download.

If it's not software but a hardware problem... writing to the disk, or something related to the wifi chip...then what can Asus do to fix this?
[Asus  Eee Pad Transformer Prime] airf0rce:
It is indeed system wide issue. Installing apps is even slower than on my two year old Galaxy S , which was pretty slow phone I/O wise to begin with. You can feel it while switching apps, copying stuff, and during the infamous browser not responding problem.

They're claiming that they fixed the application not responding issue with upcoming OTA, but we'll see. I really hope it's not HW problem, I really like my Prime apart from these annoying lock ups.
[HTC Sensation] furkey:
I've got a screen brightness issue with my sensation. I couldn't find if it because of a software issue or hardware issue. It's the 3rd time. I have started to consider it's happening because of the softwares i have installed. There had been nothing about 2 weeks. But I have installed some softwares 2 days ago and when i reboot the screen issue has started. Any ideas?
[HTC Sensation] furkey:
Here is the steps i followed:

It has started when i was using InsertCoin 5.1.4. I have tried lots of roms even the stock one but never happened. And I have returned to my original rom and did everything again. (s off, flashing recovery, rooting, supercid etc.) I have installed back InsertCoin 5.1.4.(And the firmware ofcourse) And the issue was solved. So what's the problem?
[HTC Sensation] el7145:
just out of curiosity, are you gonna mention what the screen issue is, or should we guess?
[HTC Sensation] furkey:
I can't see the screen outside. I mean the brightness level is too low. (Even when i set it as full brightness)
[HTC Sensation] doublehp:
When I set a picture for a contact in Gmail (computer), and/or different one in the contact editor of the phone, none of them are shown in the contact viewer.

I can see the photo set from computer in the contact EDITOR, but as soon as I save or cancel it, I don't have any photo left. Photos comes back when I start edition.

As result, I don't have any pic for any contact anywhere: phone book, chats ...

Sometimes I have a picture during phone calls, but it's not always the one I have set (it can be an old, and will stay the same even after edition).

How to get my contacts have a picture ?

Discussion thread, for touchpads.

I found a whitepaper in the Developer Zone on the sonyblog. From this I can find out that:

The touchpads act as a touchscreen, but they are not connected to anything.

The touchpad touch events are as follows:

AMOTION_EVENT_ACTION_DOWN (touchpad touched)

AMOTION_EVENT_ACTION_UP (touchpad untouched)

Touchpad is seen as a pointing device...
