Hi there,
I have successfully rooted and tweaked my Wildfire a few weeks ago and did some fine tuning since then (a lot to be honest).
XDA Developers has been a great help (obviously) but I got stuck at a few points.
There's especially one thing I'm a bit confused about: there seem to exist mainly four methods/ways to gain more internal memory:
re-partition the system, cache and data partitions
use Apps2SD (CM7)
use Darktremor Script
set up an ext partition on the SD card and move apps there (different methods)
Some of them could be used in combination.
I've read and experimented a lot but - as I said - I got stuck and a bit confused so I'll ask here for opinions/hints and probably a bit more clarification.
As you can see in my specs below I've already adjusted my internal partitions. Although I've gained a lot more space with that and being very selective which apps to install I don't feel lucky with my 312Mb.
My questions:
What would you choose to gain more space on the phone? Making an ext partition on SD or simply use CM7s built in Apps2SD?
I've read here about "S2E" - is this a good solution to work with an ext partition?
Any suggestions/hints/experiences?

Well to me it seems you already have your answer.
I personally use custom mtd settings of 145 10 and use absolutely no sd partition or a2sd what so ever. I've got quite a few apps but my internal memory has well over 200mb remaining.
In my opinion partitioning or moving apps etc just makes your system work a little harder but when using just the internal memory even with custom sizes seems to work best for me.

I perosnaly am just using DarkTremor A2SD and I have about 100MB of free space with over 150 apps installed (140 in the app drawer, as the attachment shows, 4x5 and 7 dots up top)

As you might have guessed that's not the answer I wanted to hear lol (but why I'm not surprised...?)
Well, in more detail I have quite a few apps I don't use very often - but I want to have on my phone for some reason. At the moment my free space is around 40-60 MB and I have the feeling that performance slightly went down a bit over the past weeks... (might be subjective though)
But anyway: that kind of honest opinion is exactly what I'm after, so thnx for your answer

Hi,you can use any of the methods you've stated in conjunction with the mtd ,the reason I don't use any apps to SD mods is due to 2 things.1.I have enough space left internally so not needed. 2.although it's very slim the chance of something corrupting in sdcard would simply cause errors for the apps moved to SD so my paranoia strays me from using any a2sd mods etc.I did in the past used dt app2sd and it worked fine.obviously if you are getting so low on memory even after the mtd then you might be best moving some of the lesser used apps to SD. In this case I personally would try the cm7 built in method . Others may differ but this is my opinion.
Ot. The scrolling cache removal in erwinp and cobje latest builds does not play nice on my phone but others are reporting scrolling improvement so I think it may be hit and miss for the benefits.
Anyways hope you find the method which works best for you.
Regards Slymobi.

I was using mtd partition and dta2sd while on cm7, they work fine together. Just make sure if you use them both to do the mtd partition before installing dta2sd.
The amount of internal storage you have (or don't have) is probably not the cause of your system being sluggish, its most likely what is running in the background, yes the built in taskkiller does a good job but the more apps you have the more it has to do to keep things smooth
I recommend an app I use called autostarts, its better than a taskkiller as it'll stop all the apps that you don't want running in the background constantly starting then being killed then starting again.........

Well, I thought I should complete the thread with my (ongoing) experiences:
Due to the fact that I've been really short on internal storage lately I've decided to give an ext partition on SD a try.
After stumbling over the really sweet & simple sounding "S2E" app I've been a bit shy to give it a go because the last (& rare) posts here @XDA dev about user experience with the app are not very fresh. But after having some issues like another member described here my latest tweaks & changes were lost anyway so I've decided to give it a try while doing everything from scratch anyway.
I'm happy with it so far - all apps on sd-ext now, I'll probably try out (with doing two nandroid backups before...) to move the dalvic cache also but I'm uncertain with that at the moment LOL

very nice - that's what I've been looking for: preventing all those apps from constantly starting up without need - thx
Next step done: moved the Dalvic cache over.
I'm pretty much satisfied so far. Everything runs smooth, stable and fast.
In numbers: Around 120 apps (100Mb) and dalvic cache (90Mb) on sd-ext, app data left on internal memory. Around 190Mb internal memory free (of 300). More than 100Mb of free RAM @ 15-20 processes running.
So far - so good. I'll watch this a while (and guess what?: I got married to a second wife, her name's "nandroid"...)

For the EXT size yes, for the swap size I'm not sure if I configured an ext swap partition at all (I'm not sure if this is necessary with s2e - thought it just needs the partition and does the rest itself...)
Also make sure that you read the warning about moving app DATA to ext, too. I even didn't try to do so...
What I've also done is setting the SD card cache to 2048KB - you can do a speed test with SD tools and set the optimal cache with SD booster.

You allocated 1024MB for Ext coz you have got 8GB Card.
Mine is 2GB so what should be the Ext size for it ?( 256MB or 512 MB would not be enough ?)
What should it be ? Ext2 or Ext4 ?

Hmm, let me think about it... When I saw your question the first time I thought that I would find it hard to go with a 2GB card. Here's why: I'm really not a music or video fanatic but 2GB are nothing if you have just a few mp3's or videos on your card (specifically your camera pics and videos for example...).
So if you say you don't need that - it should be ok.
For the size you need I could only tell from my personal experience, too:
I don't have much discipline with deleting or transferring unused stuff or garbage from my phone - so I might have a few apps installed I rarely or never use (anymore). But I don't collect apps just for fun also - so I'd say I've installed an average number of apps. 120 to be more specific. That makes 474MB used for the ext partition including installed & system apps and Dalvik cache (128MB).
So if you don't plan to install more than 120 apps, 512MB might work for you - I'd probably stuck with 1024 - even with a 2GB card - to prevent running out of space (what happens exactly when you just don't need it )
What should it be ? Ext2 or Ext4 ?
Click to expand...
Click to collapse
To be honest: I can't remember exactly but I've read something about possible problems and incompatibilities with ext4. But I'm not sure if I faced that question at all when I partitioned my card with CWM... if so I'm pretty sure that I've chosen ext3 (just in case I'd like to install a different kernel some time in the future)
Following Oleg Krikun it should be ext3 or ext4 for S2E...

Yes it might sound confusing - but there are a few things to consider also besides a simple "do it" or "leave it": More RAM is an advantage if it's true original system RAM which can be accessed fast and handled properly and stable. If you already have a fast processor and much system RAM you might also experience some improvement by using an additional swap partition.
For CM7 - especially on the Wildfire - I pretty much agree with that:
In some applications, this makes it seem as if the application never closed at all. This is not much different from traditional swap, except that Android apps are specially programed to write out very specific information, making Android's Memory Manager more efficient that swap.

But your mileage may vary.
From my experience it's a bit trial and error to find the best setup and config for your phone - you should also know that there are differences between identical devices sometimes.

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)

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.

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.

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

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…

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.

-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.

Hello.. :laugh:
I want to know what is this sd-card partition and how it helps me just in short and how can i do that in a easy way..
I'm new to all this and have never done this so wanted to know how to do it safely.. Please Do reply
My device is LG optimus P350
Waiting for ur earliest reply
When u move apps with app2sd some of data stil remain on phone internal memory. With sdext partition and link2sd all app data are moved. U can partition through recovery. Depend of sd size sdext should be no biger of 256-512mb. Of course widgets steel won't work so be careful what u link. Also when u partitioning all *our data wil be lost so backup your memory card first.

Oki..
I'm Using 8gb card and i have a free space of around 3gb so how much partition would be better and will this partition help me in increasing the ram or making my device faster ??
Can we Change The amount of partition once we have done it before ??
512mb sdext will be just fine. I've heard of some scripts that do the trick with ram but I've didn't try them. With internal memory free u should get faster, more responsable phone, and for gaming u should try some of the roms made specialy for that (gingerDx is very good and superfast, have one or two bugs but developer will fix it very soon). hope it helps
U can't change size of partition without formating all data (I think u need to use killdisk software). But realy u don't need biger swap partition of 512mb. Ofcourse sd card class 8 or 10 is preferable.

I can't use partition, i read a lot of tutorials and any of them helped me, 'cuz my mobile don't recognize the partition, but my sd make it. How can i me it work??
ps: i have sd-card of 2gb
4 now tnks
CAUTION
you should do it only if your sd gives at least 6mbps read speed.Otherwise your phone will lag even in best roms like a granny driving a lamborgini
OOwww Okay thanks for the information and i shouldn't make the partition right??
Hello everyone,
I know I'm pretty new here but I have been digging these forums for a few days right now.
I recently bought a faster 16 GB SD Card and rooted my phone to install bigger and other ROM.
But I found verry little info (maybe I didn't looked has much or at the right place) about the swap space you can create in your sd card.
What I read was that it was usefull for the system but when I look at the differents ROM thread they never or very rarely talk about a needed swap place in the sd card partitioning.
Right now I created an ext4 partition with a little bit more than 1gb and a swap with +- 400 mb.
So my question is, is it really usefull or no?
ps: sorry for my english

As far as I know, there are vrey few ROMs that require swap partition. It is usually requested in the first post of the ROM's thread.

Ok, thanks !
I will re create my sd card then
Well after a few rom tested I'm not so sure about this...
Ok they never talk about swap space. But the general problem I have when I install a big rom with Android 4.x is that the memory is always full.
Therefore the phone becomes extremly slow when I launch a few applications.
The only solution I found is to install an app to manage the RAM and free some space. But even with this, I need more ram as it's almost alway full.
I will try with a swap of 512 Mo but I have no idea how other people can manage this.
If anyone have a tip about this, it would be great .

If you use the native a2sd scripts that come with 4.x ROMs, then that's your problem. Those scripts only move data/app to sd-ext, leaving the rest on internal. Most of the memory is occupied by dalvik cache.
This script should also move dalvik to ext. Try it.

Don't forget to backup first.
I never used a swap partition. I think there's no need for it.

Thanks for your anwser but right now I'm using this rom:
http://forum.xda-developers.com/showthread.php?t=2213033
And I already moved dalvik and data to sd in the installation. I tried every option there, only data, only dalvik and both. Only both is working.
But this doesn't change the RAM used (or maybe it's not so important that the RAM becomes full?)
I also tried other 4.x rom and moved everything but at some point I think there is too many info in the ram and the Desire becomes really laggy.

creating a 512MB swap partition is pretty much useless as most ROMs don't implement it. It's a redundant partition which could either be used as extra sd-ext for apps or FAT32 space for music etc. It can cause problems as well depending on the order of partitions.
Even if somehow it could be used, it won't suddenly turn the desire into a phone with 1GB RAM...that's not the way it works. In cases where it is used, only a small swap partition ~25-32MB to occasionally swap a few things in and out of memory. Even then whether it actually makes a difference is dubious imo.
I would recommend repartitioning from scratch again, remove the swap partition. You don't need it, and the ROM you're running won't recognise it's even there.
It's laggy not only because of RAM, and can't be solved by magically adding more of it . Android memory works differently as well, so free RAM is wasted RAM, you shouldn't have to monitor how much is free at any given time. A big part of the lag is simply because it's a JB ROM which is simply very resource heavy on the desire relative to GB ones.

Thanks for the informations.
Right now I only have an Ext4 of 1 Gb + 15 gb in Fat32. I didn't had the time to recreate the partitions again. So won't do it.
Well I thought it was a RAM issue because without the ram manager app some functions becomes hard to load like.
If I receive a call the phone rings but wait some time before loading the info to display about the call.
Or if I want to answer an sms the keyboard takes time to load.
Same thing with the apps.
With the ram manager it generally loads faster but some time it gets buggy because there is too much work to do to free space (I suppose).
Well that leave me not alot of options about the capacities of the phone .
Maybe just go back to 2.3.x
