hello developers !
no points for me, I just bringing here to our development
Many of us are disappointed about the reading speed of the SD Cards on our Android Phones. It doesn't matter if you have fast 10 Class SD Card, it performs very poorly on the Phone comparing how it performs on the PC.
The clue is the Cache size for reading from SD Card. It's set to 128 KB, on some ROM's even to 4 KB!
You can check for yourself your Cache size by looking into this file:
/sys/devices/virtual/bdi/179:0/read_ahead_kb
You can change it manually but it will be reverted to default on the reboot. The changes need to be done permanently by loading the script on the startup through the init.d.
Or you can flash the CWM zip files that I made for you.
You must find which Cache size fits best for your SD Card. In my case its the 3072 KB Cache size.At best, use the Root Explorer to change the value, then run SD Tools Benchmark - finally flash the CWM zip file that fits your SD Card.
Here are two screenshots - the first one shows the reading speeds with the default Cache 128 KB and the second one is with the 3072 KB Cache with my Class 4 SD Card on CM7 RC2 by Charnsingh.
The Benchmark is made with the SD Tools program.
If you want to convince yourself of the speed improvement after applying the fix, just open your Gallery and see how fast it loads the photos!
Suggestion: 2048 KB Cache size performs at best for most of the SD Cards!
Some of the ROM chiefs have hardcoded this values in the init, that can't be changed - only by the chief himself.
Some of the ROM's already contain this tweak in another script that is saved in the init.d folder. Probably it's tagged with the number 99 in the filename to be sure that it's executed at last. You have to change it there.
Rafpigna - the HD2 Android chief - pointed that out over here.
For ROM Cookers - add this line into init.rc file:

I see most of you use link2sd. But for those who use s2e, have you already experienced a time when you boot your sgm, you suddenly lose all your apps and you can't check or uncheck the Applications box?

Did not experience this problem. Been using s2e for a long time. You can check the Application data by going to s2e settings and check Advance mode. Restart s2e, and you should be able to check it. But I think its impratical to move it to sd-ext. The developer had it default to not move it. I mean, what's the use of your internal memry if nothing's on it? Afaik, the developer chose not to move it since it needs a high I/O speed and internal mem best suits the requirement. It's only practical to move it if you have a class 10 sd card.. still its the users choice, so..

A sd card class 10 certified is a must if you don't want to loose so much speed compared to internal memory.
Although reading speed is not that prob for many card, writing is the more important factor. There class 10 should give you best results.
You can also gain more speed setting a higher sd read ahead cache size. You can do it via an app (sd speed increase for example) or a rom which supports it (cm7 rc5.5 squadzone for example).

I use emanon V4 and i have try both of darktremor n s2e..maybe darktremor is better than s2e but i like to use s2e
Its not just you who experienced s2e corrupting the partition and destroying all partition data suddenly. It happened to me thrice and got me pissed like ****. Now I removed partition, formatted my 8 GB memory card. Flashed cm7 by subskype. Using the default cyanogen settings options to set default installation directory to external memory i.e memory card. Am done with this partition crap.

To everyone, thanks a lot for cooperating. I think I'd try s2e, link2sd, darktremor, and the move to sd card settings in cyanogenmod each in a week. Then I'll see which one I think is best.

When you say it is slow, you mean launching and using apps is slow? Or the linking/moving process?

What class is your sdcard? It might be that the card itself is slow?
You have the same problem when you install apps directly on the sdcard?
Sorry to post more questions than answers, but I really wanted to try it, but if it slows down apps, maybe, I will try something else.

Ok, but do you which class it is?
It should be written inside a circle on your card.
Class 10 is really fast, for example. But if you have a class 4 card, or less, that could be what slows down apps.
Btw I prefer Link2SD because I can choose which apps can go to the SD Card

Maybe that is why it is slower than on your internal memory.
Did you notice the same slow down when you simply move apps on SD, the "classic" way?
By the way, I installed Link2sd yesterday, with an ext4 partition on a class 10 card, and it seems to work fine for now.
Only weird thing I noticed : with the rom I use, link2sd was unable to install the mounting script if i selected ext4 as a partition type.
When I selected ext3, it worked. I read that some roms have trouble with ext4, and others with ext3, but I didn't think I could mount a ext4 formatted partition as an ext3.
I'm using link2sd with a class 10 sdcard and there still are no lags...Everything smooth and fast (Rom: CyanogenMod7.2 RC1 by vo-1 MIRACLE Edition V4)

Link2sd is the best for me. I am using link2sd about 3 months and I can say that's the best. But if you dont think like that, you can try app2sd or s2e.

the rom itself change ext4 u made to ext3....
A little update.
After one day of use, I managed to have my sd-ext partition messed up.
It could only be mounted read-only.
I had to reinstall everything.
So maybe I will try some alternatives like a2sd.
For those who tried these apps, which partition type do you recommand? fat? ext2, 3, or 4?
I'm using Link2sd. DT A2SD is buggy to me. Link2sd works great on CM9 beta 8 with my Sandisk 8GB Micro SDHC Class 6

Follow this guide, and remove the ones that you don't need:

Also, follow this : http://forum.xda-developers.com/showpost.php?p=30595805&postcount=1555 if you want some more space in ROM (/system partition)
It's not more RAM that you need; it's more internal memory. Unfortunately, if you want Play Store, you don't have much choice but to delete certain things which aren't essential.
Use ICS or GB based roms if you don't want to delete things to make room for Play Store.

Easy all you need is to create a swap partition.
Now there are two ways
1. You go into recovery mode. Then advanced then partition sd card then select the ext partition size then it will ask swap size select whatever size you wish then let the process complete. This method will erase everything on your sd card but will give more stability and better performance than the next method.
2. Open Google play then search for swapit if you find it then download it I think it is free if it isn't then download swapper but I would still suggest swapit. Anyway whichever you download create a swap file through the app in sd card and not ext. After the process is complete you will have increased your ram.
You have successfully increased your ram but now you need to configure your device to recognize the extended ram so download ram manager(pro) from anywhere open it and select multitasking then see the device performance in the app it is like a speedometer it will be around 60 now just clear ram and swoop it becomes full.
You will surely see a significant change though most of it depends on your quality of sd card I have no problems hope even you don't.

Hey Guyz Today i come with a trick which will help You to Increase the internal memory of your device. Its the most easiest method and best of all... It requires no Root Access and no
need to partition Your SD Card!!! This method actually reduces your used memory. This easy way to gain at least 40 mb of internal storage on your phone:
1. open dialler, and press *#9900#
2. Then select 'copy to sd card'
3. Wait until finish, Done !!
Results vary because it reduced about 50 mb on my SGY Duos and reduced about 7 mb on my friends SG Gio. Usually work well on unroot device & non partitioned SD Card May be usefull but wont recommend on
devices with high memory!!!
