I've been trying this patch (manually, not the complete script), but I have found this actually slows down the folio. There is a reason why flash-based devices don't have a swap. When writing large blocks to swap, the system will stutter heavily. The slow flash disk of the folio will not help in this. My test shows it is actually slowing down quite a bit.
Even with the low RAM of the folio, it is still faster to just start/restart an app than to swap it away in a swapfile (resulting in 1secs of stutter) and then getting it back anyway from disk.
ZRAM is something similar. Tough here I can understand some improved use cases, but:
- you take away precious RAM
- then you swap out programs and compress them (uses a lot of CPU)
- if you swap the program in again, you need to decompress. Granted, the decompress might be a little faster than restarting the app.
- because of the lower useable memory, programs do have an higher chance than before to be compressed (vs killed without ZRAM), so decompression (with ZRAM) statistically will happen more than restarting (without ZRAM), making the gains of ZRAM point 3 less.
- I don't think this works correctly with huge processes (e.g. browser), and will just see that less RAM is available, and will not swap out parts because the whole memory region is still in use (best case, it will continuously swap in & out parts, making it again slower)
I'm not completely trowing out ZRAM, as it is still beneficial with some workload combinations (I think a large collection of small apps is the most optimal case)

I successfully ran V6 SUPERCHARGER using the terminal emulator in Cm7. Had to switch to Hackers keyboard to type the command sh V6* which starts the script from the root of sd card. I used the first v6 script posted and was very conservative to avoid any boot loops. i am benchmarking system and running some favorite apps to see if it is a winner or not. So far system booting faster and seems real snappy! There is a CM7 and CM9 version but I would DEFINITELY have a backup sd card ready and know your way in ADB in case something goes wrong. Remember to eject/ reinsert your card if you cant access your sd.

So far no problems. Gui is faster, internet is faster, games and apps load faster. Very good hack.
Videos
BE WARNED! it seems the sacrifice you make for a faster deaktop is slightly broken Ducati hardware acceleration. I am not sure if it is just an issue with .flv,s or affects other media types. The Youtube videos sometimes refuse ro play in HD but will play in HD if you dwselect HD with an occasional hickup. Not sure if it is the way this rom accesses Ducati and the way this script modifies memory management.
Interesting. Ill take a look at the source and see if theres any special tweaks to be made.

Thank you. It would br a good find for our community and would put us on par with the other Xda developer sites.
Moved To General
As the OP contains no development, this should be in the General section
It uses fairly moderate values for the tweaks, I can verify that not only does it not brick the tablet, but the tweaks it can apply actually work. I've noticed about a 20% improvement in memory management, along with i/o improvements (which is weird, though I assume it's due to the memory tweaks and overall improved system response).
On the flip side, it has by far the most annoying, frustrating attempt at a text UI that I've ever encountered, using literally about a hundred separate sleep functions. Still, cool find.

I am using it now as well..But it's not so snappy like a regular netbook..is it possible to make it more speedy ? or is it because of my Slow SDCARD ? Class 10 makes any difference ?
Hi.
I use Ubuntop 1.1.0 too, and with Nottachtrix and Faux kernel, it's fast enough for normal use.
Even faster with Faux Kernel 1.45GHz, but high battery drain
If you want it any faster, you'll have to overclock your phone. Faux's 1.45 makes it run pretty good, but in turn drains the battery faster. Remember, this is still a phone.
Definitely Ubuntop!
I have attached a screen of the multitasking i once had on my lapdock. Ubuntop is a fantastic mod, it allows use of synaptic and other linux applications without the need to install all of the various mods to do it. It also removes some of the bloat from the webtop, which makes it run faster.
Another notable feature is the ability to mount an NTFS formatted drive, I have connected my 250gb external drive with an NTFS and a FAT partition on it and it could see and read/write both partitions.
It also has two different themes, UbuntopLX and Webtop+
And an install script for the basic programs that most people want. It is a huge improvement over the stock experience.

Is it possible to underclock the Phone when using it Normally (Undocked from lapock) & then overclock it manually when docking to the lapdock.. & what are the constrains ? I mean my Atrix heats up very quickly on stock kernel.. will it be a problem to run the webtop @1.45 GHZ ? esp. the heat generation ?

I use system tuner to limit memory usage, auto kill set to aggressive. It occasionally still tells me im low on memory, but you just have to close apps when this happens.

HOw is it that you managed to install anything at all on the Ubuntop mod? All it ever did was throw errors at me about... not having GNOME or something, about missing keys (which I tried to remedy) and in the end, the WiFi on the webtop commit suicide before I could fix anything. Now, the WiFi works in mobile mode (even in the mobile window it works) but FireFox refuses to connect. So now I can't install anything from online. And additionally, it constantly complains about not having permission to DO anything, when I KNOW I'm rooted. Super user (su, as it is named) is in /bin and everything. What gives?
If it helps, I'm running Nottachtrix 1.3.1 and used webtop2sd 1.1.0
Because, right now, your phone sounds preeetty sweet. A functional webtop would be the perfect thing for school work.
Hello fellows, anyone is using swap2cache script to improve your SK17 perfomance. Would you recommend using it?
Thanks in advance.
Considered all that's out there about how andorid manages ram i have never really seen the point.
Android will open processes and activities for as much free ram as it has, and when you need to run something it just closes all useless activities and cached programs if necessary. Enebling swap2cache will just give your device more space to occupy with "junk" which will be sitting there eating up on battery life and performance...In my personal experience i find it to be more useful on older devices which had limited ram, 512 is enough to run most stuf out there (there's a discussion on android genral about makin 2gb which concludes that for now it's quite useless..) plus it's only adding 64mb extra...it's not going to be that big a change.
I tested it personally, and my rom (also using miui) without swap2cache usually has 400-420mb of used space before doing a system dump, with swap 2cache enabled it was always full at max...
Not to mention sdcard life.... constant swapping on it, reduces lifespan obviously.
Also it's very much slower than system memory.
Sent from my ST15i
Hi Guys, thanks for the info I will try for myself and report it back.
Just to clarify swap2cache works in the internal partition /cache not in /sdcard so it is supposed to be faster.
Yeah you are right it works in the system partition but you may want to take a look at swap2zram as it works in the ram itself! Faster than system memory!
hit thanks if I've helped!

LoL! my bad. I wasn't even reading right. I was automatically thinkin' it was swap2sd -.-
EDiT:
Xkernel uses ZRAM by default...
Here is my experience, apparently this extra 64 mb only make a difference when you play heavy games like Asphalt 7, N64 emulator, Nova, etc.
Because without swap2cache when I played this games with the sixaxis controller app this one always closes in the middle of the game. However with swap2cache enabled I can play this games with the sixaxis app without problem :laugh:
Hope you find this information useful, if anyone is interested I'm attaching the script:
- Uncompress it and copy it in /etc/init.d/
- Set 777 permissions to script.
- reboot.
Gaming Mode Script
As you all know our phone with ICS update struggles in gaming even at games that don't use a lot of ram.
The constant restarting of services that were killed are simply drag every game to hell.
There are many apps in Play Store that are doing what my script does.
But the problem is that most facing a problem in closing the swap file and they just re-enabling it.
That's a problem because even with a class10 SD card the phone is a lot laggy with swap.
Programs need seconds to open and to go to homescreen sometimes needs even 5 seconds and more.
Here's the solution. A simple switchable Script that will give you the extra juice only when you want to game hard.
UPDATE:
Added swap in partitions.
Requirements:
Needs working Busybox and SU
Instructions:
1. Copy the script from inside the appropriate zip to /data or /system and make the permissions to rwx-rwx-rwx (0777).
2. Use Script Manager or what you want,
and make a widget in your homescreen for easy access. Be sure to enable SU in options!
Also install SM widgets so you can set your script as a shorcut in homescreen. That way Smanager will not take any RAM.
3. Tap the widget and after it's done close SManager and you are ready to rumble and enjoy lag-free games.
4. After you are done, press once again the widget and the swap file will be removed. Enjoy your phone back to it's lag free condition.
swaponoff.zip for swap in a file
swappartonoff.zip for partitioned swap
Config:
You can change preferences by editing the script. DON'T use notepad! it will break the unix encoding that it's needed for the script busybox commands.
SWAP_FILE: Where to save the swap file.
SWAP_SIZE: Swap file size in MB. Default is 128MB
SWAPPINESS_OPTION: How much to swap. Default is 10, to avoid unnecessary swapping.
For partitions chage SWAP_PART="/dev/block/mmcblk0p3" Change 3 to what your swap partition number is
Notice:
That will give you lag free games only. Using swap always on will make your phone laggy in general usage.
Also always close the swap file before connecting the phone to usb mass storage!!
Credits go to mrvek for his swap script, which I used as a base.
If you like it, please press thanks!
did this script need partition swap or not?
Can I ask why will a swap file increase gaming performance? If it does, why will it lag the phone during normal use? What's the difference?

The system can push te apps into swap. Without need of to kill them(before it kills tehm but they keep restarting afterwards so this is why some games lag) Some other games need alot of memory to even start. So when you have swap. the game can use all the 300mb ram(at least 30 are for frameworkcs, etc)
And CTCaer. I think you shall add that it srecommended to use swap partition. Its better ... at least for me

Nope. It makes use of your sd card. It mounts a certain file there.
A partition for swap was never needed. Also if you use for example noop i/o scheduler for sdcard, this will make the need for swap partition obselete. Because it will not prioritize the writing/read and will work like if you had 2 partitions in sd.

Well in ICS every library and framework and the default use of gpu make use of a lot ram. More ram than GB.
Most games need 60-120mb ram to play.
That makes android to kill services running, like widgets, homescreen, messengers and more to free ram.
The problem is that many of them the restarting almost immediately (like whatsapp) and others restart like normal when android sees that
there's free ram (like when you enter a menu in game, ram usage drops).
That creates an endless loop and make the games laggy and the worst of all makes the touchscreen unresponsive.
So the extra virtual ram helps so that these services remain open and not make an impact in your playing by restarting endlessly.
Android and in generally linux makes use of swap only for apps that are not needed.
That means that your game will be mainly in the real ram and will not lag.
In contradiction swap will make your phone laggy for general use because every time you open an app, another app or services will use the swap file (like homescreen).
So when you return to homescreen or to an app that is cached in swap, android will retrieve it from it to the main ram.
This will cause a delay to opening the map and a general lag feeling for 2-5 seconds (according to how much of it went to swap).
I even disabled zram for almost that reason (it takes cpu cycles), as i needed it for game before using swap only when gaming.
To sum it up,
only one thing I saw from using this script when gaming: ALL games now feel like i have gingerbread in my phone.
Only downside is that some gameloft games need a little more time to load, but when android gets done with swapping the unused services, it fades away.
Extra tip: Enable swap when using google maps. Same win like games
Whats the different with ram xpander apps
I used this apps and create 1020 Mb memory swap
This apps used my sd card for supporting the internal memory
And this minimize the force closed apps when we need a lot of ram to open hard apps

The only difference is that with my script you don't need an app and that app will take ram as it's always there.
And because some swap apps don't let you disable easily or even at all the swap.
The script is mostly for people that want to have extra virtual ram only when gaming or using google maps.
And btw if needed i can make a script like that for swap in partition.
So how to create it
Or i am just edit your script from 128 to 1000 Mb swap

But i have Next Launcher that gets 25-35mb ram and it's locked in ram. Beatiful widgets, switch pro widgets, contacts, whatsapp and more that are open and it never lags with or without zram.
Anyway if your rom needs more ram then this script is not good for the swap to be always on. Better stick to an app that will auto switch it off when mounting to mass storage and to auto start it at boot.

I uploaded a script for partitioned sd cards if you want.
But yeah that's how it's done.
With deadline and swap in scard, your kernel will prioritize the read/write to the sdcard between reading files for your game and read/writing for swap.
Noop will use 1st in read/write command -> will be the 1st out.
If you use a partition for swap and deadline, android will prioritize the read for your game only.
The scheduling of read writing for swap partition and together with the game will fall to SD Card. Which is like noop. 1st command in ->the 1st to be executed.
I hope i explained the main differences about swap on file or partition.
Install Ram Manager instead. lol

Well you can add physical ram to a phone, you can flash a kernel or bootloader that reallocates some ram, but this is device specific and often takes some very intelligent programmers to make this happen.
The other way is to use virtual ram in the form of a swap partition, this will use sdcard or internal data or whatever partition you make work, function as ram, but it is slower than real ram and depending on how you use your device may make it slower altogether. I believe this is the method of increasing ram that you did, the easiest way to see if it worked is to open a terminal emulator and type
free
The final way is with compcache or zram, both squash ram and has a similar caveat to using swap as it may make things worse.
A few Google or xda searches should explain this a bit more than I have
