Hey,I am going to "clean" install CM 7.2 Stable.I am done with Custom MTD Partitions and want to set up an ext partition on the SD card and move apps there.
Preparing for "S2E"(simple2ext:https://play.google.com/store/apps/details?id=ru.krikun.s2e&hl=en )
I have got 2GB SD Card.
What should be the ideal configuration for a 2GB card in terms of :
(1)Ext Size
(2)Swap size
And what should it be ? Ext2 or Ext4 ?
According to this :http://forum.xda-developers.com/showthread.php?t=1432459
“Choose Ext2, Ext3 or Ext4 for partition type based on whether your kernel supports Ext4. If it does choose it! If you don't know choose Ext2 to be safe.” Now how to find out whether your kernel supports it or not ?
Does "swap" really make any difference ?What’s up with this “swap” partition ?
It’s so confusing.Some people claim that “swap” is like virtual RAM and more RAM means a more efficient (and faster) device.
Here are the posts supporting “swap” :

http://forum.cyanogenmod.com/topic/44675-how-to-configure-a-sd-ext-on-htc-buzz-wildfire/
While according to “Cyanogenmod” (http://wiki.cyanogenmod.com/wiki/Swap_and_Compcache ) and some member swap doesn’t make any diff .on android devices.
If that’s true and swape is useless then why so many forums going gaga over it on XDA at the first place ???It makes no sense. So bewildering.
Any suggestion ?Any help would be much appreciated.
Thanks.
You should try 256Mb or 512Mb ext2 partition as per your convenience with 0 swap size.
After partitioning your card you need to install an a2sd script and use a2sdgui app to move apps.
Or else you could install link2sd app and i guess that moves apps to ext partition without needing a script.(haven't tried it though)

Thanks for the reply,so you mean "swap" doesn't make any difference in speed and efficiency ?
I am a bit baffled.How about "S2E (simple2ext)" method ?
I have read about that here :

Is that a good idea ?Any suggestion ?Any help would be appreciated.

Swap is used when you run out of RAM space.I dont think we need it on our wildfire.Just select 0 as swap size.create SD partition from recovery,that would be easy as you don't need to be confused between ext2 or ext4.

I have read in some forums that "swap" increases the RAM i.e more speed and efficiency,no ???
Here is the page:

Just wondering,if that can be done on Wildfire.
Android apps are specially programed to write out very specific information, making Android's Memory Manager more efficient that swap.

You've kind of answered your own question with the link you've provided, if you think swap may be worth using, backup your SD card create a swap partition and give it a run for a while, if you think it isnt then backup everything again and create a partition without it. I had swap enabled when I first created a partition but saw no benefit at all.

Okay,I am thinking of giving this "swap" thing a try.:fingers-crossed:
Again,I have got a 2GB SD Card.
What should be the ideal configuration for a 2GB card in terms of :
(1)Ext Size (What should it be ? ext2 or ext4 ?)
(2)Swap size
Any suggestion ?
I am gonna flash CM 7.2 Stable and use "S2E (simple2ext)".

I successfully made sd-ext and moved apps there (http://forum.cyanogenmod.com/topic/44675-how-to-configure-a-sd-ext-on-htc-buzz-wildfire/), so now I have 170 MB of free space for new apps!!
Question: I noticed that my phone slowed down a lot.... does it depend on SD type (read/write speed)?
Which is the best type / brand of SD?
Is there any other setting I could optimize for speed, when having Sd-Ext enabled?

Moving Applications data to sd-ext slows your phone down.Don’t move “application data” to sd-ext.
I suppose you are using “S2E”,right ?What’s the format of your sd-ext ? ext3 or ext4 ?
Go through this thread :http://forum.xda-developers.com/showthread.php?t=917377
Personally, I prefer“S2E”(supports mounting sd-ext as ext4)

Yes ,your card’s speed depends on the class of your card. An SD card's speed is measured by how quickly information can be read from, or written to, the card.Speed varies with the class of the card…Class 2 (2 megabytes per second), Class 4 (4 megabytes/second),Class 6 (6 megabytes/second) and so on…

I used ext3, what experience do you have with ext4?

It's working great and ext3 should work fine too.
Acually ext4 provides better performance with journalling.
If you use an Old CWM recovery, it will convert it back to ext 3 when you backup/restore.
ext3=ext2+journalling
As ext4 is newer file system,new features have improved the performance and reliability of the filesystem when compared to ext3.
Journaling can be bad for the life of an sd-card (coz you do more writes).If you are not worried about life of the card, and the choice is based on filesystem performance only then ext4>ext3>ext2.
Ext4 can be used with journalling switched off.So "ext4 without journalling" will be best in my opinion.
There is a debate going on over it,check that out :http://forum.xda-developers.com/showthread.php?t=800353
I just want to know wich is the best to do it. I though I had a ext partition aligned with the SD card to use it as internal memory... but know Im getting I have no space left. So I suppose I did something wrong.
Any help is appreciaded.
Thanks in advance !
Do you use any sd-ext scripts? I suggest you Mount2sd.

I will reformat my SD Card and try everything again. If i do it right, should the internal memory change in size?
And wich should be the partition sizes?
Thanks in advance !
that depends on the hboot u are using. about ext4 partition, most roms require ext4 1gb - 1.5gb max

Hello. I am new to this forum. I am curious how many people really use a swap partition and what is the method of of using swap in htc wildire s?
I am well aware of Linux OS and understand the need of swap but in case of android does it really improves something?
Hi.I will try to explain you what i know: :laugh:
-swap partition is needed to work some ROM's,combinated with ext partitions.
-you can create swap partition with MiniToolWizard
-in same time,you can create with CWM recovery.
If you need,i will give you a link for MiniTool.
If i helped you,please click "Thank's" button.Have a nice day !!
Does android automatically detect SWAP Partition on SD Card and utilize it automatically?
Yes(i think).

does it? i thought the kernel had to had zram enabeled to allow swap use? i might be wrong though..
Most roms auto-detect, but I'd recommend checking with the devs before partitioning your sd card.
Also, unless you have a class 6 or upwards, it won't really do any good.

Where did u find that info?? Is class 4 mmc that bad????:s
never use a swap partition on any android phones. It does no good. The swap partition are made with your sd card which is more than 10 times slower than your internal memory. When an app is loaded or is sent to swap partition cache memory, it takes time to copy or load the files.
Android already has a system for moving unused apps to cache memory. So, let android do its job.

This can make phone slower? Just that ?
How can i know if the swap partition is enable ?(i don't know if i have a swapt partition,i forgot that)
And if i have,all i need is to delete this ,just that ?Or i need to reinstall the rom ?

Just ignore his comment. We need Linux swap. Without it phone gets laggy. I tested it myself.
Download minitool partition wizard home edition. Its free Google it. After installing it and insert ur sdcard via card reader and run the program.it will show ur partitions.
You don't need to uninstall ur system. Just make nandroid backup using recovery. Re format only the ext and swap partition. Based on wat ext u had earlier. All partitions should be primary.
Then from advance recovery restore sd-ext.

@Edu: just search xda for details of swap partition. There have been number of discussions regarding it and all have ended up denying the use of swap partition. These have been comfirmed by much experienced devs, who have been cooking roms for more than 3 years. But still if you dont believe, i would recommend you to google a little and then make the decision.

But sir without it the phone gets very laggy. Means every games run slower. The antutu gpu score gets lowered.
U can easily get 645-630 3D with swap. But without it u can't cross 615. That may seem as little gain but for games it becomes a big issue.

Maybe that is because the extra cache memory are directly transferred to swap memory. Games which require huge cache memory can be of profit. thanks for the screens btw
@op : just take nand back up and back up your sd card. Try the swap partition thing and if it is beneficial, go ahead or else you know what to do

Swap Partition
Hi, i'm new here so i'ld really appreciate anyone who can really help me on this:
I created a swap partition(256mb) on my sd card for my HTC wfs. now after making series of research on swap partition, i found out that swap parttion is necessarily not needed and even if i av to use the 256mb i allocated is too much. Now i need help on how to delete the swap partition without losing my DATA ON MY SDCARD. PLEASE ANYONE WITH THE RIGHT HELP

that's kinda not possible i guess..with mini partition tool you can delete swap or ext3 partition and create ext4 visa versa..but if you wanted only fat32 it isn't possible.
either if you have ext3 or ext4..open mini partiiton tool..delete swap and delete ext3 or ext4(which one you have)
and create partition(ext3 or ext4) from remaining free space...in this your fat32 will be unchanged..
but obviously ext3/4 will be deleted..bt its okay to hv swap partition..256 MB hasn't big space..the whole concept of swap derived frm link2sd i guess..latest int2ext scripts dont need swap..but int2extv2+ need.

Copy all of your data to your pc, then format the card via clockworkmod recovery. It should remove the partition. If not you can try gparted for linux or easeus partition master for windows pal.
If your trying to keep your ext partition but without a swap then copy your data to the pc, then select partition sdcard from clockworkmod recovery. Just don't select a swap and you will be fine
Oh, and make a nandroid backup to back up whats on your ext partition

thanks dude really appreciate but going by what you said i have ext3 and already used a2sd that means if i delete ext3 definately i'll lose my data. that is what i'm trying to avoid but since you said my 256mb aint much a big deal, i think i wld leave it then.
Thanks a bunch.

Is there a possible way to use a swap partion on my buzz?
Yes, of course you can if your kernel supports swap partition, after you create the partition using the recovery (or better with Gparted) to configure I use the application "swapper2" (the market puts it as incompatible but installing the apk everything works.
there are no major performance improvements (actually with our processor can be seen slowdowns if you do not use a micro sd class 6-8) in fact is quite unwise but if you want to try ...

is there a method to that?
Tbh, I don't really know much about this but I've read @wedgess post in such type of q. He said that u can practically increase the system partition but then u will have 2 part with ur other partitions...ur total memory of every partition will be same though. U can decrease the memory in data partition and increase system partition.
Afaik this method is very dangerous and can cause hard brick....u can search about this for more info
