Guys want to know your thoughts or any comments/suggestion it is safe to use this app?
How to use it in a right way??
Please send me a feedback for this..
Thanks and Godbless(^_^)

Im using a CM9 BETA 3 ROM with 16GB class 4 SD CARD
Sent from my GT-I8150 using xda app-developers app
It merely creates a swapfile, and enables it during boot.
If you're using CM9, you can make your own swapfile.
HOWEVER
you'll want, at the very least, a Class 6 SD Card. But I personally recommend to not use a swapfile unless you have a Class 10 SD Card.

you should use at aleast class 6, min write is 6mb. class 4 mean just 4mb
but ok, you can try it and decide yourself. just remember to lower your swappiness, because its maybe become not responsive if your swappiness too high (100 max). its depend on your card write speed.
i'm prefer use swapper2, its good, and its free :cyclops:
im suggest you should use swap partition instead, its easy, just use minitool partitian wizard home (just google it), if you use windows.
just split your current partition and make linux swap partition.
then put your swap partition path on swapper. usually on GT8150 is /dev/block/mmcblk1p2, or just try change that number, (i'm hard to identify in first time, but easy then after you found the right one).
everyone said if use ram swap will degrade you card life. but if i looks on my card box, its says lifetime guarantee, and i believe most of brand also give lifetime guarantee. thats mean your card will not die with usual use. except if its fell to water or physycally damage.
i'm using one from motorola back than, with linux os, and i'm always use swap. its almost 3year and my card still ok, until my phone cant breathe anymore :angel:
Actual,y I DON'T RECOMMEND Using Ram Expander App
IF You Like Gaming don't Use Cm9
use a custom GB, such as gaming rom
they are optimized for Good gaming experience

Hi pepoluan,
Is the default kernel for CM9 support linux swap partition or are you referring to swapfile that created in your sdcard fat partition (swapfile.swp)?
If this possible to support linux swap partition with a custom kernel, what kernel is it?
Thank you

Maybe because you doin sdcard benchmark while swapfile is on. sdcard is to busy writing while doing benchmark. I my opinion.

Create a swap file instead. Simpler, and you can rotate daily between several swap files, thus rotating the wear on the SD Card...

That well depends on the quality of the SD Card and how "swap-happy" you configure your kernel to be...
By rotating the wear, at least we're giving the MicroSD Controller a fighting chance to allocate spare blocks to the worn-out blocks. Some MicroSD Controllers provide device-wide spare blocks, so rotation is not necessary. Other Controllers provide 'zoned' spare blocks, thus we must rotate to ensure that there won't be too many blocks worn out in a zone.
And cheap MicroSD cards might have too few spare blocks, rendering a guaranteed short life...

What are the possibilities of using our 2gb of ddr program storage and re allocating it as system ram?
Even if it isn't pure flash (slow speed) I imagine it would be better then nothing, we could always store programs on the sdcard.

very good, this post actually explains how to make a swap file (on /cache which is fast nand!).
if you want a swap partition you could a) use part of the 2gb /data partition for a new swap partition which you create in a project-voodoo like manner -> not very easy to do as you would have to repartition /data before boot OR b) just make a 2nd partition on your external sd card to swap on. a lot of people (me included) actually did this with their htc magic.
but to be honest i don't think that you will gain any speed improvements with this, on the contrary your system will be slower an more laggy... i found swap even worse on the magic with ~90mb of user-available-ram. if you want to try it nevertheless, it think the swap file on /cache would be a good start!

you would have to repartition our external sd to have a second (linux swap) partition.
then use mkswap to set the partition up and after that call swapon. swapon has to be redone every time you restart but you could place it in a playlogos1 script to automate that.

Bad, bery bad idea, MoviNand is not in any way releated to DDR. It's waaaay slower.
Also, RAM is designed for virtually unlimited data read/write counts.
NAND memory is not.
What would be the benefit of using swap space? Nothing. Data is being read/written in filesystem in the end. No improvement in performance. (It could be seriously degraded).
This behavior is totally against Android core design principles. Android doesnt use swap because it doesnt need to. Programs not fitting into "RAM" are being closed with their state remembered. When program is re-launched it is loaded from filesystem and its state is being restored.
If we had "swap" space, it would become really messy. Just imagine:
System wants to close program X, resident in swap, it needs to:
- restore program from swap to RAM (talk about additional ram needed)
- close program, resulting writing state to FS.
i was talking about this sort of thing with Ryza and Voodoo guy they said it was too much work
i'm forward with the idea of using a Swap drive in RAM or external SD
to prevent over usage on the internal SD
This means external SD would need to be powered up at all times -> battery drain (it is present with APPS2SD - or whatever this name was)
Wuld this mean that we would have extra ram available for running apps...like SGS task manager will show more than 311Mb RAM ?
If this is the case then I am very interestied, since I don't care about speed so much. I just need to run an app that currently can not run due to out-off-memmory (needs 130Mb of RAM) for pure presentation purposes
There is a app in market called swapper2 which can make use of the swap partition or creates a swap file for use. I had been using this app since my HTC MAGIC and now on SGS.
I'm currently using swap partition that had been created earlier in my class 6 SDCard. Works on both eclair or froyo kernels on SGS. So far I am not complaining, with swappiness 20, there is not much of memory hog or lag due to opening too many apps or single memory hogging apps (like flash on browser) on my XXJPK, the swap memory gets allocated and deallocated as you can tell from the swapper info feature.
But the battery effects is something to think about though, sdcards are cheap so I don't mind sacrificing it. The other way is to create a swap file on the rfs and use it if you value your sdcard. The screenshot provided is a normal usage of my device with a few apps running at background (Still gonna be 300+ RAM, nothing magical about it though) and I had also used minfree tweak on the kernel.
You can try and see if it helps in terms of performance for a few days. I cant vouch for the swapper a lot as I'm using it myself - I am more uncomfortable without it though. What Xan said does makes sense but there are rare times when the things that doesn't makes sense gives us surprises.
A good read up and comments from people who had tried and used it in different scenarios...

Hi,
I wonder where is the truth about moving apps to SD card. I have HTC Desire which has really low space for apps. I used to use Darktremor A2SD script with CM7 but according to some users this can really slow down my phone while opening apps when I have slow SD card (I have 4class Kingston) and it probably does, becuase I experienced this issue very often. It was horrible and I decided to use different partition table. Now I have dalvik cache on internal storage.
Today I read that the more space I have on my internal storage, the faster the device is. The question is: Is this true? And is true that apps moved to SD (not using A2SD script) are slower?
On a very slow (cheap class 2) it can be true.
I have class 6 and not noticed slowdowns.
Theoretically - the internal NAND is faster than the SD Card, but if the ROM is set up correctly, it is unnoticeable.

So where is the problem? When I used A2SD script I experienct heavy lags while opening apps (Handcent, gallery, etc.) sometimes 2-5 seconds. It was really bothering. Full wipe helped everytime but after two days lags were back.
Now I am trying have dalvik on internal to see how it behaves.
I believe that class4 is not so slow and I also read that Kingston cards are sometimes much faster in tests, sometimes similar to other class6 SDs.
AFAIK, it depends on the ROM, too. For example I had no lags with AOSP ROMs, just Sense ones.

You might. Again i Think it is affected by many factors. For instance, when I was using Gingervillain 2.7 the phone was fast even with 20 MB left on internal - then I moved internal & stuff to the SD and had around 96 MB free - but did not notice that it was running faster.
Try using s2e app from market, I'm using that and it works very well

I read about low ram and something called HSPL but i have no idea what it is or how I can flash it
can any one help

thanks for your help

is this for you to move your apps to or is this to use like ram it appears that my phone is running low on ram for the running processes but not room for storage ( I moved almost all my apps to the sd card already )
thanks for your quick reply above
Think its for more memory space for apps, but it must create more system memory as well, because before I used it I had moved all my apps to SD, but I was still running low on memory. Since Ive used apps2sd ive had no more memory shortages
Hope you like that Rom I've used it my self and its a good one.

sounds like you don't quite understand the difference between ROM/storage space and RAM/memory.
A lot of people use memory and storage interchangeably but that is not accurate.
The OP is having a problem with low memory/RAM meaning that the OS and running programs are utilizing too much RAM, IE too many apps or processes are running or there is a memory hole/leak somewhere. He is not having a problem with storage space or room to install additional applications or store additional data.
you can use the V6 supercharger or Car-o-dope tweaks (i think thats what it is called) they will increase your RAM
If you get the RC4 release of the V6 (its still stable but not on the main page) you should do option 7 and 20. Be sure to nandroid before.

Thanks for the heads up on the RC4 release of the V6 I put it in and it did help my memory on this rom . So after partitioning and running the script I just have one strange question.
Does this rom have a built in power battery saver? i am not running any sort of battery saver, I am running a task killer still but only to see free ram since the script does the task killing now. I notice my wifi shuts off when the phone sleeps and that I have sleep mode that enables at about 11pm. Is there a way to kill this since I do most of my computer geek stuff late at night.
I have looked all through my apps and i have nothing installed that i believe could be doing the power conservation stuff

Hi everyone,
What about adding swap support to custom kernels to overcome SGW ram shortage? Couldn't post to dev forum so posted here. Please someone reply.
I have my SGW now for about one month and its my first android device.
I havevsome years ofvexperience with Linux and while i was playing around with my phone i have experienced som lag while switching homescreens on Go Launcher.
I have quite some stuff on screens and ex taskmanager widget shows me
that my mem is easily filled when doing some more stuff.
My phone got root and terminal also set up so thought
i go make a swap file on internal sd to give phone possibility
to swap mempages out of ram when needing mor mem.
Been there done that, saw that even if swap helper progs (i.e. mkswap,swapon,
swapoff) exist gives error that kernel lacks swap support.
Dont know why swap not implemented in stock rom, went ask internet for
custom kernel for SGW. Reading Kezras custom rom thread and beeing unable to post
questions to him on his thread , got me here.
I ve also read on internet that there are custom kernel for other devices with
swap activated. Though our fon has quite good processor it lacks ram,
so i wonder if custom kernels here have swap activated and perhaps start discussion here about pros and cons.
Thanx for any replies.
Hi its me again,

Hi there irishpancake! Just testing the V6 supercharger myself seems pretty ruthless...keeping my used RAM at 230MB almost permanently and lag free!

I ve tried the script you suggested,
and it 'feels' very promising.
I appreciate also your speakout for activating swap support in custom kernels/roms so anyone could choose freely what way to go.
Still virtual ram don't interferes with good memory managment and
with swapspace you have a little extra even if you dont use it and the
slow access is relativated through paging. Wonder if one can set page granularity in kernelconfig ?
By the way if anyone could point a
Rom/kernel developer at this thread as i cant. I would like to hear their opinion on all that.

Hi 2g11 man.....
sorry, I just saw your PM, about V6, and just to say, I find it definitely snappier, and as you have noted, very good on the memory management.
I do not have enuff knowledge to actually give figures or stats, but it just feels much faster, and responsive, lag-free.
I am still using the Update 9 RC4, so I will try out the latest version Update 9 RC6 ASAP....
I use Launcher Pro, just coz I hate TW, and it is remarkably good with the V6 tweaks........and I am still Stock ROM 2.3.6 [KJ6].

Now that we can swap the space used by Internal Storage over to our External SD card, would it be possible to use the Internal Storage as some sort of extension to RAM?
We got 1.7GB of storage that's not doing much of anything. If all of it or even most of it could somehow be added on to useable memory, we could have more programs open at any one time and still not lag.
If this can be done, what's the best (safest/easiest) way to do it?

We got 1.7GB of storage that's not doing much of anything. If all of it or even most of it could somehow be added on to useable memory, we could have more programs open at any one time and still not lag.
If this can be done, what's the best (safest/easiest) way to do it?

Make it into swapfile, you mean?
If the kernel support swapfiles, yes it can be done ...
... BUT ...
... you will shorten the life of the Internal Storage, and possibly, significantly.
And when the Internal Storage dies... you can't replace it.
And, yes, it will die, sooner or later... it's not a question of "if" but a question of "when"... and I'm sure it will die much sooner if you put a swapfile in it...

How many read/write operations before it burns out, you reckon? Would it be more or less than a physical drive?
Coz if this was possible, it would be very nice to have 2GB mem. LOL

A spinning-disk drive has no limit to its rewritability.
A very-high-quality flash memory cell can last 1'000'000 write cycles. But I don't believe that our Galaxy W use that kind of flash memory. So, a more common number is 100'000 write cycles. When you're talking about swapfile, you're talking about at least 100 swaps per day, and possibly more. If you do not tune other parameters so that Android will not use the flash unless it absolutely have to, you can easily go over 1'000 writes per day.
When the counter passes 100'000... well, I'll say prepare to buy a new phone because the internal storage is not replaceable...

So better to map that to External then, if at all possible?
Any ideas on how the system could use Internal storage to improve our Wonders?
