[Galaxy Tab 10.1 General] jokeyrhyme:
Android is an OS within an OS: a Java VM running on Linux. I think this is why it has taken so long for the abstraction layers in between to mature to the point where it is reliable to use hardware acceleration for everything. Because of these extra layers, I doubt it will ever be possible to truly eliminate all latency from Android (without dumping the JVM).

The hardware of the Galaxy Nexus is not revolutionary in any sense. The CPUs and GPU are quite old. The fact that ICS performs so well on it is a good indicator that the OS has seen major optimisations and improvements. I think we can expect better UI responsiveness across the board on any ICS device, but I would be pleasantly surprised if it was as smooth as iOS.

Ever since the NDK, it has been technically feasible to build an OpenGL browser engine with almost the same performance as Mobile Safari. However, as Android already includes an unaccelerated version of WebKit, third-parties have never been bothered to produce such a browser. I'm glad the built-in WebKit engine has seen some drastic performance improvements (although the HTML5 support is still poor).

I only recieve lag when i put on a live wallpaper , but not on my upcoming ROM ;D
[Galaxy Tab 10.1 General] Sighx:
If you think about what you would have on your android homescreen and what you would have on the ipad.. THE IPAD ONLY HAS ICONS.... If they cannot make that smooth.. they're hopeless..ANDROID on the other hand.. has widgets and weather etc etc .. of course there can't be COMPLETE smoothness.

I have a Galaxy Nexus. While scrolling is 'smoother' is many areas (i.e. scrolling through contacts is smooth), the UI is not consistently fluid and smooth throughout the entire OS (i.e. 27 messages in an SMS thread and it struggles to scroll - very jerky and stuttery).

I have created a video here (unfortunately low frame-rate doesn't really show how bad the problem is):

And here's the (as official as it gets) explanation from a Google employee:

https://plus.google.com/105051985738280261832/posts/2FXDCz8x93s

I bought into the marketing BS and lying reviewers who claimed the Galaxy Nexus was 'lag free'. I feel so cheated. Wish I had done my homework instead of being an early adopter.
[Galaxy Tab 10.1 General] varsas:
I guess I can understand why you're disappointed but if at present a device needs to effectively 'pause all processing' to allow for a lag free UI then I'd rather Google continued working hard to improve efficiency; what's the point of a 'multi-tasking' OS if it isn't multi-tasking.
[Galaxy Tab 10.1 General] bigbrovar:
Here is my 2 cent on the whole hardware acceleration smoothness lag free issue. I own a galaxy s2 and a galaxy tab 8.9. while android 2.3 flies on my sgs2 without single lag everything is so snappy same can not be said of my galaxy tab. Before now I use to blame honeycomb for the laggy problems on my galaxy tab (its becomes really obvious when swiping between screens and doing a screen rotation) until my colleague got a galaxy tab 7 plus which uses an exynos chip (instead of tegra2 that comes with the 8.9) The performance difference between the 7+ and the 8.9 is like night and day. the former is so smooth and snappy I rarely notice any lag whether during screen rotation or while swiping across the home screen. This got me doing search which revealed that most of the lags experienced on many honeycomb tablets are infact as a result of the hardware limitation of the nvidia tegra2 chip (which is not as powerful as nvidia would have us believe) even though tegra2 can handle some very power 3D games it struggles when it comes to some 2D tasks. for example it is not capable of screen rotation be passes that to the CPU which is responsible for the slight lag when rotating the screen.

Can ICS fix this problems? For the most part, I hope the nvidia guys really work on releasing a driver which might perhaps work round the issue and produce a smoother experience. However I won't be placing my bet on that happening anytime soon.

For those interested in discussions by android developers on perceive android lag when compared to IOS and WP7 .. google plus post. Very educative and talks about the problems and what could be done to fix it. https://plus.google.com/104142377567758692050/posts/9YE1jRzfb5N

Google's answer is to wait for faster CPUs with more cores. I don't think they want to fix the issue, it's too difficult. The result: a 3 year old iphone is smoother than dual-core Android handsets.

As you can see from my video, I too own a Galaxy S2. While it is 'smooth', it's not perfect. Scrolling in contacts, for example, it jittery. It does ok, but when it comes to a heading or something it has to render in the ListView, it stutters. The stutter, while subtle, is still very noticeable (especially for those coming from the iDevice world). The best way to describe it on the S2 is it's not "consistently smooth". To me it kind of feels slippery and erratic (although scrolling in the browser is fantastic, even with embedded Flash videos).
[Galaxy Tab 10.1 General] BarryH_GEG:
Teg 2 was the first of the dual-cores. When it was the only dual-core, people marveled at it. As Qualcomm, TI, and Samsung released competitive chips it became apparent Teg 2 was inferior. Until 3.2, it was the only chip HC supported which is why all the 10.1 tablets originally used it. So here we are again. The Teg 3 is out as the only quad-core. People are marveling at it. While Nvidia may have gotten their act together, I'm willing to bet newer quad-cores from the other manufacturers will surpass it. My next tablet and phone won't be Nvidia powered.
[Galaxy Tab 10.1 General] xManMythLegend:
The answer is no. The reasons outlined above.

It'll take a complete overhaul of how things are coded apparently.
[Galaxy Tab 10.1 General] emuneee:
I never marveled at the Tegra 2, because even at the time the first dual core phone and tablet debuted (LG Optimus 2x + Xoom), it was almost (or was over) a year old.

I think the Tegra 3 is more capable at taking on its competitors than its Tegra 2 relative was taking on its counterparts.
[Galaxy Tab 10.1 General] slaman:
I'm running that ROM on my Tab, and the lag is quite evident...even compared to this phone.

Running v8 of task650. It is very smooth for me but having said that the ipad2 is still smoother and this is becuase once it detects a touch it stops evrything and dedicates all resources to services the UI unlile android where UI is run as a normal priority. Android can get there soon as someone modifies a bit of the code
[Galaxy Tab 10.1 General] raqball:
Then I have a magical Tab because I have little to no lag.....

The iPad comments are hilarious... Someone already stated the obvious, the iPad is a tad smoother because you can't do anythin with it and it simply needs to process icons....LOL..

Also whoever said that iOS runs better because Apple spends months testing it.... LOLOLOLOLOL.... Now that comment really made me laugh for several reasons.....

The iPad with is mega 512MB of RAM is faster because it only needs to process pre-cached icons.... Jailbreak it to add features and enter more lag than if left stock....

iPad = ease of use and simplicity <<<< Android = options and customizations.....
[Galaxy Tab 10.1 General] PookiePrancer:
I too have a magical one. Only time, even with stock HC, I ever noticed any lag at all was swiping between home screens with a live wallpaper running (oddly enough, tapping one edge of the screen or the other to go to the next Page is fast and smooth). No clue what the deal with live wallpapers is, but other than that, everything is smooth.

And yeah, a jailbroken iOS device: massive battery drain, and depending on what other cool apps you load up, massive lag. So I'll take a static wallpaper and the power to do what I want any day over a walled garden.
[Galaxy Tab 10.1 General] awakatanka:
I had a ipad2 and a 10.1v and still have a iphone 3gs and a desire with a beta ics rom. Ipad is a bit faster but if you only use icons and no widget on the galaxy then it is smooth to. The android browser just sucks a bit and the may replace it with chrome. The iphone lose from my desire with a beta ics. That one is already smoother then 2.3 that was on it. Yes i expect less lag with ics and much more power to the user then you have on a ipad/iphone.

Dropped the ipad2 because i couldn't do with it what i want without jaibreaking it and dropped the 10.1v because samsung support just sucks. ( no offical updates, stock is still 3.0 )

So i'm looking for a new tablet and dunno wich one to buy
[Galaxy Tab 10.1 General] jtdc:
The Android and Apple products have different user markets. No one here can never ever say that their android is more smoother than ipad. Dream on to Jellybean on 6-core(?)... Heck, even the much touted quad-core transformer can't beat the year old ipad2 on this lagginess issue. Some posts even compare to the 3 yr old 3GS!

But then the android tab is designed for a lot more capabilities and customizability. It just boils down to which market segment do you belong.

I can't agree more with the statement above. On "ANY ROM" on "Honeycomb"... and that pretty much majority of things running on Android 3.x Tabs today, all using the crappy tegra2. I'm curious though to assess the Exynos powered Galaxy Tab 7+ superior performance though.

Does it mean you'd prefer the 4S more than the Gnex?

Same here. My delighted experience on the Galaxy Tab 7 on PowerVR SGX540 tells a lot. That same GPU is used by later devices and even the latest Gnex and still delivers. The apple camp used it on their devices and is the king of butter. Even the upcoming Playstation Vita use it. Does that tell us something about others (cough nvidia, cough adreno...)

Sadly, ICS is not the cure. Look for feedbacks of Gnex-ICS owners in terms of UI or vs apples, in which ICS is even optimized onto OMAP CPU with a GPU powering the years old original Galaxy S/Galaxy Tab 7. Few links I read,

[Galaxy Tab 10.1 General] siggehandf:
Android will never have the same smooth scrolling and animations and scrolling as ios. So, if you value smooth scrolling and animations, stick with apple. Its simply the way operating system works. Iphone will drop everything its doing to help you scrol and in that sense it will never be really good at multitasking. Android value you finger movement as high as loading and updating the pictures on the webpage your browsing.

Get over the whole lag crap, its not lag, it is just the way things work. More powerful cpus can help minimize it, but it will never be like Ios.

I am not bothered by it, my desktop computer acts the same way...
[Galaxy Tab 10.1 General] mark.m.moran:
Guys, with Task v8.0 what speed is it running at? Is it OC to 1.4GHz??
[Galaxy Tab 10.1 General] Isilmalith:
Actually, I tend to disagree. Since I upgraded to a SSD, my Windows Computer just flies. Should try a Multitouchdisplay to test scrolling though, you can't compare it to mousescrolling :/

Windows 8 Dev Preview is another example of this. Buttersmooth, ultra responsive. And this is a full blown OS!

@Thread

It seems as the lag-problem is deeply rooted within the OS, a compromise to enable other things - I'm a bit disappointed by that, but I hope it will improve over time. I'm really looking forward to the first ICS Roms. Maybe it really HAS seen some performance increasements and optimizations. I'm pretty content now with ADW Launcher EX + Task Galaxy ROM, it does a good job for me - But faster and smoother is always welcome, as I am the kind of person that gets pissed of about slow apps/systems :D

@mark.m.moran

I think it is OC if you'd like to, as it uses Pershoots Kernel?
[Galaxy Tab 10.1 General] mark.m.moran:
Cheers mate. I love it so far. Maybe I should download SetCPU and see what frequency it's set at....
[Galaxy Tab 10.1 General] jtdc:
actually it feels to me much of the bad rep of this lag thing is just exacerbated by the tegra2/honeycomb combo. how come on even my underclocked arc running crappy adreno 205 and gingerbread, i don't feel this inferiority complex against ios?
[Galaxy Tab 10.1 General] roland0fgilead:
My Gtab 10.1 may not scroll as smoothly as iOS, but using that as your sole reason for choosing one tablet over another is completely asinine. I choose Android for what I perceive to be a superior user experience over iOS, and the fact that I can customize it to my liking. You can go on and on about what devices have a superior architecture but the bottom line is that you buy what suits you, and the Tab 10.1 suits me - and the majority of this forum - just fine.
[Galaxy Tab 10.1 General] raqball:
I agree 100%...

The iPad is a tad faster and smoother but its not night and day like some claim (and loose all credibility doing so)...

It boils down to what the user wants:

4:3 or 16:9 screen

Customization or simplicity

Market or App Store (mainly driven by what smartphone they own)

Flash support or not

Stereo or Mono sound

Both the iPad and the Tab are awesome Tablets and one can't really go wrong by choosing either... I had an iPad2 and sold it for the Tab because I quickly became very bored with iOS but that's me..

I rarely, if ever use portrait mode so the 16:9 works better for me...

[Galaxy Tab 10.1 General] siggehandf:
Got my Nexus phone yesterday and that is without a doubt, the smoothest Android experience i've ever had. But, that is also one sweet ass phone, really. If the galaxy tab can reach anywhere near that kind of performance. Then it will be almost completely lag free. There are still some minor lag now and then when you open up something for the first time and it has to load a lot of images and so on.
[Galaxy Tab 10.1 General] crecsky:
I don't have any lag issues on my device. I know that for some reason on touchwiz you have to hold your finger on the homescreen so the menu pops up and change the tab you're on from live wallpapers to more and my jerkiness disappeared.

Also, I'm using ADWex with a 4D vertical launcher and I don't have any problems. But I also don't load my tablet with a tonne of widgets, although I've got a bunch of apps on it after the 10 beeeeeeelion sale.
[Galaxy Tab 10.1 General] zerong:
Good question :-)
[Galaxy Tab 10.1 General] fransarj:
the reason why iOS will ALWAYS be smoother is because the UI thread is given priority. For instance in the browser, whenever you touch the screen and scroll, the OS stops doing everything and focuses responding to your inputs. With android, it tries to BOTH load the page AND process your inputs.

here's a good read explained by a guy who interned at google:

The reason Android is laggy:

[General Questions and Answers] :
Does anyone still use an OQO Model 2? If so, how would you rate the performance in comparison to say, a Galaxy Tab 10.1? By performance, I mean, browser performance, things like netflix, etc. I am very intrigued by the OQO and I am thinking about losing the tablets and going to a Model 02.
[General Questions and Answers] oqoman:
I have had an OQO 02 for a few years, and cannot fathom the thought of parting with it. These days I only use it as a "bedside" computer with 15" TV/Monitor, Full sized keyboard and mouse, using the OQO dock w/dvd r/cdr rw. I have in the past used it as my primary computer w/a triple monitor setup and a host of other "proof of concept" projects including using it as a mobile voip platform.

A few things to consider:

It would NOT be a good substitute for a tablet. Screen is too small. But can you put that tablet in your pocket?

The screen is not capacitive ie: "touch". It is proprietary Wacom - needs a Wacom pen to use for screen input.

If you decide to get one, only get the 1.5 ghz model, the 1.6 ghz model has, well, bad motherboards.

It has a noisy fan.

It has an underwhelming VIA CPU with only 1 meg RAM - I call it the "chugger" as in the "The little engine that could".

On the brighter side, Windows 7 works best with it and it should work even better with 8! I have only used Win8 Preview on it and it works fine - but I couldn't do an "upgrade" (loading previous drivers from existing Win7) because it says not enough memory, <1 meg. A full, fresh, install worked fine. I will wait for Win 8 RC0 to arrive before I commit.

The machine is very durable - I am hard on my equipment and the OQO has fared very well through my abuse.

Batteries are hard to find, although available with search - at the moment I am having two batteries recondtioned/fixed locally. They are available on ebay (used), also.

Finally, the OQO is a niche product. You have to want the very small form factor with full Windows OS (or Linux/Mac) to appreciate it.

See OQOTalk and OQOasis for the best information.

Hope this helps!

Hi OQOman,

Thanks for replying! You have really given me a lot to think about. Of you wouldn't mind, could you tell me, is $300 a fair price for a model two with the specs you described? I have found several on eBay, but it seems most don't actually have the Wacom digitizer. I really want to try to load an older version of illustrator (maybe CS or cs3). Any thoughts?

Thanks

[General Questions and Answers] oqoman:
$300 seems to be a fair price. Be sure to get the pen. It's a $30 (when new) accessory.

I would look at Oqotalk and Oqoasis forums for the oqo 02 and accessories. Those two forums are the "Bible" for OQO. I wouldn't buy anything until I had read those boards.

Adobe should run on it. Remember it is only 1 meg RAM - but owners have used it.

All OQO 02 have the Wacom (inductive) screens.

OQO-2 resurrection

Hi, a few months ago I 'inherited' an OQO-2 along with a CD/DVD 'dock' and power-supply. It came without any manuals. The battery was about to explode, so I removed it and soldered the leads in the empty battery-housing to allow the power-adapter to run the computer. It's been up and running for a few months with an Ubuntu LinUx installed by the previous owner. Unfortunately it seems that I cannot set the screen resolution properly(it only allows for 640x480) and so I am never able to see the lower- and right-third of my screen. This makes it hard to do much of anything!

I've connected an external monitor to the dock, but I cannot get the computer to switch to it. Is there a specific keystroke-sequence required to switch to the external?

I've also attempted to install Windows 7 via CD/DVD. When I power-on the computer it'll access the CD/DVD, but it always returns to loading Ubuntu without allowing me to install Windows. Do I need to set the CD/DVD to 'boot' or to 'first-boot' in BIOS? If so, how do I access BIOS?
