[Q] Moving apps

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.

Ok. And do you think that the more free space on internal I have the more speed I can get while using the apps?

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

Cm7 slow because of app2sd

I have data2sd installed with 200apps....data2sd is very slow n lags alot...I want to use link2sd as its faster but will I b able to hav 200 apps and does link2sd use the internal space even after linking all the files to sd card..

Link2SD does, in fact, continue to use internal space.
Depending on certain criteria (which I don't know), certain apps will continue to throw some portions onto internal memory.
Even if you're as anal as I am about going into Link2SD (after enabling the "auto-move to external thingy") and then MANUALLY grabbing linked apps and pushing them over to SD... you will still cry, swear, and wonder where all your internal space went. ;-)
I'm at about 50-60 installed apps and I'm down to 28MB left internally (only started off with about 57MB though, due to custom ROM limitation (deodexed).
Good luck,

Which class is ur sdcard?

Okay, so i have counted my apps, and i have 177 apps on the phone, and some of them are really huge, and it just works fine.. i am using a data2sd by jikantaru ... i guess your sd card is slow, or you use the bad data2sd script ?

try to class 8 up sdcard~

Class 6 will also do.
Dear god, what are you people doing with 150+ apps ?

LINK2SD Reducing Performance?

Okay, I have Link2Sd installed on my device, I have almost one gigabyte of apps in it. I was just wondering, that can it be the problem, cause my Arc S' performance has became pretty awkward(gaming performance is ok, but scrolling it the menus and so on). Anyone else having Link2Sd and having the same problem? I really wouldn't like to uninstall this app, because it does wonders!

What class is your SD card?

No it does not affect performance.
Bear in mind that apps that are moved to SD (whether it is with Android's native method or Link2SD) do not suffer from performance decrease depending on the class of your SD. Apps do not run from the apk, it's not like Windows that apps run from the corresponding exe file.

Yeah, good point. Of course the apps theirselves are installed in the internal memory. Didn't come in my mind Looks like I have to find another causeto my problem

Use a file cleaner to clean the cache/ history
Try using links2sd to clean the dalvic cache.
Hope this helps

Link2SD Plus version
I am using the latest version of Link2SD plus, which basically allows linking of all application files (apk, dex, lib, cache and data) to the second partition (ext2/3). Obviously this is a huge space saving benefit with the extremely limited internal memory of the Xperia Arc S.
Unfortunately, apps like Chrome, Skype and TuneIn radio (which require around 100MB each) have serious performance issues in this case; they become completely unresponsive and impossible to use.
I've experimented only moving certain types of the application files and noticed that this is most possibly caused by the cache files being linked to the sd card. By un-linking the cache files the apps become usable once again, but that takes quite a lot of space obviously. Has anyone else experienced this problem? Is there another solution?

I use link2sd on my arc s and i installed over 20 apps, it's fast.

I, too, must be another problem

Hello @ArmorD,
Link2SD performance relies on your external storage mediums read and write speeds; in this case your MicroSD cards speeds.
The MicroSD card which came with Sony Ericsson Xperia Arc is just a slow Class 4 card, with terrible read and write speeds.
To get better performance you have to replace the MicroSD card with something a bit faster; any class 10 card would do the job. I would recommend Samsung, Kingston or Sandisk MicroSD cards, they're all great.

Get a faster card
Get a faster sd card, preferrably class 10, they are cheap, been using link2sd forever n even now with kitkat, still fast

I have an 80mbps micro in my axiom and I am running link2sd flawlessly best buy has sales all the time I picked one up for like thirty bucks worth the speed.

[Q] How much user memory ?

Hi all.
I'll probably buy this phone for my wife.
Samsung say it is 4gb internal memory but doesn't say nothing on partition size.
as I'm an HTC desire user and i know that a very low internal memory can really be a pain.
so can anyone tell me how it is parted by default ?
4gb, it seems to be cool ... but How much for System/Data/SDcard ?
best regards.

ok thanks.
GSMarena only say 4gb storage with no more details.
so i guess it remain 1.7gb for apps, am i good ?

3D games
They said that ACE2 also works for 3D games, but 3D games does have bigger file size, I believe it will consume much of the RAM specially if the game has "game cache". I installed blood and glory: legend, file size is 320 Mb plus other stuff to unpack to start the game, now I can no longer install another 3D game. Is there a way to transfer the game to SD card and play it? The game cache needs to be installed on "Android folder>obb" on the internal SD card. I tried to cut it and paste it to my external SD card then the game did not work. The app is trying to connect to the internet to download the game cache again.
Any idea?

Dude you really need to read all of the Galaxy Ace 2 Development, i believe you will find the answer, and its not ram that you need to be concern, its storage and you need to swap the internal and ext SD.

[Q] RAM

Is swapper/swapper2 works on our device?
Also is it posible to expand the ram amount by
Using externalSD card (class10)/internal to be partitioned and be
Used as RAM? Like the vold.stab.
Larger RAM could be benificial to high memory apps and games

Swap memmory used mainly if more ram needed.
bt it might decrease the life of SD card.
if you want to use swap on grand, just need custom kernel with swap support.
