Hi
does anybody know, if official miui is based on ext4 and if not, is there any way to convert it?
thx for answers
Mate, you really should use the search function. This is the second time I've answered this question recently.
Ext2/4 lagfixes (including voodoo) are used due to the slow speed of the rfs file system which samsung decided to use.
MIUI is cyanogenmod based, and as such, uses yaffs file system. Yaffs is quicker than ext2/4 so other lagfix solutions are unnecessary and incompatible.
Hope this helps.

Dear all experts,
hope i m not waiting everyone's time. it seems that not many have asked this question, so maybe i ask. pls help answer or revert me to a link which can explain this.
Question: whats the difference btw the diff extensions? i know from wiki that ext4 is the successor of ext3 and ext3 is the successor of ext2. so shld we all convert our ext to ext4 for better features?
THANKS in advance!!!
They are all versions of the ext filesystem, evolved over time.
see http://en.wikipedia.org/wiki/Extended_file_system
Your question is moot because going forward (2.2+) apps will be installable on the FAT filesystem so no additional partitioning is needed.
Isn't ext2 supposed to superior to FAT?

Except it is up to the developer to enable that, only one app so far that i own has apps2sd enabled. and FAT32 does not work with root apps, so EXT is still very relevant.
I noticed that in ext4, after a short time, performance goes down. Converting from ext4 to rfs and again in ext4 improve performance, as if all the files are defragmented.
could be true?
Could anybody create an application that does all this automatically by recovery as a defrag?

Its ext4 not exit4.
sorry
I'll try and find some links but there have been quite a few threads on this already. not to any great conclusion, as theres pros and cons with battery life etc....
By the way why has someone thanked you for your post lol???
Heres one: http://forum.xda-developers.com/showthread.php?t=800353&highlight=file+system (admittedly that doesn't include jfs)

Because i'd like to know too.
I've just converted back to RFS file system and the phone seems to be faster.

I had the exact same theory as the author! Some sort of fragmentation going on I reckon.... with any file system over time. Regular conversions back and forth really helps!

which one is better in sgs i9000¿?
Why not ext2?
Doc's Rom DamianGTO kernel
somebody says that ext2 it's not reliable so... i didn't put it.
undoubtedly ext4.
I've never lost any data using ext2, that said, I'm currently using jfs all, with system reiserfs. Phone flies.
Insanity 8
now i'm using fugumod all with jfs also because in the fugumod post somebody told that it was the best but i don't see anything different from ext4
Wrong section and old debate and since google used ext4 for Nexus S most of the dev use it for Galaxy S. Because who know better than google what is best or not
yeah, but testing the filesystem with some apps the jfs beats ext4 on galaxy s i9000. at least it's what i read in another post.
I've used ext 4 a lot before and currently am on fugumod with JFS and I can honestly say my phone never felt faster!
I'm only a day with it though, but haven't had any problems so far. But I don't think it's as unreliable as ppl make it to be, I believe is used without trouble in linux as well.
Now that a lot of FS have been added for us to check out, I think we need a discussion on the best one to use.
This should be in q&a and not in development.

I did a test and the results show that JFS is better in I/O.
I wonder why so many people are so fond of EXT4.
A combo like reiserfs on system and rest on jfs seems like the fastest way to go.

ive heard that if your battery dies on JFS it will corrupt!
Strange Problem with JFS/ReiserFS
In Development Thread there is mentioned, that there is a problem with the language/timezone settings on some systems, but these settings are not the only one affected.
also ringtone/message tone "usb debugging" and more settings seem not to be loaded correctly after reboot, when i convert all partitions to JFS or ReiserFS.
there's no problem with ext4 here...
there is also no problem if i just convert /dbdata to JFS or ReiserFS, but if i convert any other partition my settings are gone again.
where is the diffrence between the ext4 and the jfs/reiserfs driver here? shouldn't the fs be transparent to the userspace part of the OS, or are JFS/ReiserFS partitions mounted too late at boottime?
pls help, i do not want to stay on ext4 and the default.prop fix for language is not enough for me due other settings are affected as well...
i'm running FuguMod 3.5-ultra on JVB

I met the same issue when using JFS filesysem with the ZSJPK rom.
At last, I surrender myself to EXT4
Hi,
Does any one know which Android Version Samsung OFFICIALLY fixed the stalling/lag issue for the SGS i9000? Is it even officially fixed?
Just that I'm recommending a phone for someone I'm not too close with and dont feel like loading on CM7 for a stranger
Searching only gives me millions of results for One Click and Voodoo solutions. I don't want to tell this person to go through these steps.
Thanks!
2.2.1 is pretty smooth and fast. 2.3.3 also, but there are issues with battery life and stuff that can be fixed but require knowledge. So, I think 2.2.1 ROMs are the best option for someone who doesn't want to deal with custom roms and kernels and rooting. Of, course a custom rom and kernel or just a custom kernel can make the phone not just smooth but blazing fast.
Hm, can you confirm that the Stallling issue is actually fixed from 2.2.1 onwards?
Specifically the problem when you click Market/Market > MyApps/Maps/Contacts and it takes ~30 seconds for it to load.
I'm not too concerned general chipiness/lack of finger-tracking smoothness.
Sorry for the paranoia , just that i hated the stalling before I was on CM7.
Officially? None. Samsung have repeatedly announced that users of their latest updates "will experience smoother performance".
They announced that with 2.2 and 2.2.1 and I'm on JVH and can confirm even JVH benefits from not running on the rfs filesystem. Yet they've never acknowledged a specific issue that creates lag, even though everyone on this forum knows exactly why and how to fix it.
Actually all stock samsung Roms run on rfs file system including the 2.3.3 ones (which means JVH too). The problems you're talking about are generally fixed by changing the file system from the stupid samsung's rfs to usual linux ones - ext4 or ext2 (ext 2 makes it extra quick in the GUI coz it quite improves the read-write speed) - everything opens immediately. Just stock 2.2.1 with changed file system will make the phone open the things you're talking about right away
Thanks for the replies.
So basically the problem exists for all Samsung ROMs, just to a lesser extent from 2.2.1 onwards. As proven by http://www.youtube.com/watch?v=g1B2fstyrRA, 2:13 mins. How annoying!
Hm, not sure i can reccommend an unhacked SGS
I would say 2,2,1 usable without any lagfix ,
Before needed a lag fix .
But ten million users on 2.1 dont know what needs fixing lag whats that ???
SGS 2 no lag .

Hello guys..
I've already search about this in XSP's part but not (yet) found one, so i'm decided to ask
Sorry if this question so noob :fingers-crossed:
Okay then, is there (possibility) mod/tweak/method to use SWAP partition for increase RAM in our beloved device??
Hmm, in my opinion this method can't use easily because the most important thing with it is kernel. Correct me if i'm wrong :fingers-crossed:
Why i want use it? Okay, there some method to solve this like use RAM Manager PRO, deodex ROM and debloated apps, or use Custom ROM which have minimal or basic android packages. Yea it help in some case, BUT I need more. Sorry for this b*ll**** reason
Thanks

Swapper 2 can also be used to setup a swap FILE as swap, but didn't work in SP with stock kernel. Looks like our stock kernel doesn't have support for swap..
I am also looing for RAM swapp. anybody can help?
