For /system and /cache this is absolutely not relevant: /system is mounted read-only most of the times (except for example when deleting pre-installed apps via Titanium Backup) and /cache is always reproducible. This means that you also should not need journaling of ext4.

/data is much more important so it is essential to have a "save" filesystem there. Still ext4 is not unsafe and data loss on a journaling filesystem is still not easy. As far as I know, the "additional security" of RFS comes from sync calls on file close. This usually leads to slower operations and higher system load. Nevertheless Samsung seems to have optimized the RFS driver in the latest GB releases. But for what price?

Is RFS today still as robust as it was in Froyo? Or did Samsung throw some robustness over bord to achieve a better perfomance? As RFS is at least partly closed source it is hard to tell....

The difference between the two filesystems in terms of performance seems to be rather small lately, however time will tell how much RFS will fragment over time using the device.
[Galaxy S I9000 General] zziggy:
Using all ext2 here. Love it.
[Galaxy S I9000 General] bofh999:
Yea and ext4 help here a lot ... lol

Man you get a memory loss anyway

point is not when data get written - point is when you write to have a short strict operation to reduce chance of damage datafile itself

So explain me what differnce it make if your filesystem got none,1,2,or999 journals if data is stored in ram ?

btw youre wrong - when data get written depends on the app not on android

and most apps like phone/mail ,.. got the usual way - data produce data written

difference is they dont have 100 files open all the time to write - like usual desktop programming - many uses more like webprogramming -

task done - task written -

however how excatly this is used is of course takse of the dev who wrote a certain app

in many cases memory loss doenst matter like you get a mail - during that total loss of power - next programm start mail get retrieed again

(its an rfc standard that a pop3 client can only delete server mails AFTER he wrote them on disk - so in worst case your mails double but you dont loose em)

PS: i work with datastorage every day - believe me

theres no journaling - no raid - no replicating filesystem that gives you real assurance for your data

the only thing that helps is a backup - and the backupserver is mirrored to another server far away
[Galaxy S I9000 General] gsw5700:
Use ext4 with no journals on system and cache. Remove all unwanted apps and services. Try and get as much memory as you can (I use semaphore bm) I also freeze facebook and voodoo when not in use, it all helps, can also defrag file systems by backing up and restoring, use tweaks wisely, use 1 at a time to see if they make a real difference. I also tend to use stock ROM with tweaks and custom kernel to get stability, jazz it up using themes. Use odex as this is a bit faster. Use tuned gps. conf file. Find best LMK value for your own use

So on stock JVT should one use ext4 or stick with RFS?

i ovserved also no difference with patched libsqlite.so / libsqlite_jni.so

and fugutweaked app_process / system_server

what i mean is that overall phone responsivnes have not changed

but maybe some numbers did - but i am not a benchmark_number_w...e

i rather use a stock mady by samsung_dev not someone experiments leading to instability or so to gain 100 points in some test that i will not notice in everyday use :)
[Galaxy S I9000 General] pikachu01:
The patched sqlite is made by me with sources and is an approved method by sqlite. :/ you can google for it if you want. The positive effect is only towards db writes. Nothing else.

like i said i see no difference as an enduser not a benchmark_follower

[Galaxy S I9000 General] pikachu01:
What I'm actually saying is that Linux will delay writes before committing it to the disk, with most of the information residing at the RAM before being written in a contiguous manner.

It makes a difference when you have no journal vs journaling. Most servers in the whole world doesn't need journaling as it is battery-backed, no not battery backed as in our phone's battery. Battery backed as in they have an emergency power supply that will activate in less than a hundredth of a second in the event of a power failure. With no power failuers, the risk of data corruption that is caused by power loss is greatly reduced.

The one you're mentioning about data corruption is the data corruption that happens when disk failure occurs. Yes, it happens and that's when backup is useful.

I'm not wrong at this. I'm a long time Linux user to know that this is basic knowledge. You're handling data on the outside, while I program for Linux, I might say that I'm a better person to know what actually goes on :P

Try googling for Linux buffer cache or try reading this:

http://linux.about.com/od/lsa_guide/a/gdelsa44.htm

The problem is not data loss on app data. The problem is when corruption on ext4 filesystems render the system unbootable or cause a bootloop.

P.S. I work with Linux every day and I design highly complex microprocessors that runs Linux :P

And I know that data redundancy is important enough to a company's lifeline (if the company relies on the data like Facebook) that the company itself will have backups at an interval, with actual power loss being something that would only happen 0.001% of the time.

If the company doesn't really care about the data, well, you could say that no matter how well an OS is built for securing data, it'll not be enough for it :)

which would be the best kernel to flash if you want a very smooth and fast ext4
[Galaxy S I9000 General] $omator:

[Galaxy S I9000 General] MrIwik:
None, try CM7..
[Galaxy S I9000 General] pikachu01:
Cm7 us based on ext4 on data partition and yaffs on cache and dbdata :/
[Galaxy S I9000 General] MrIwik:
Really? No fooling?

It is not so much a "Lag Fix" as much as it IS the file system that it uses. You don't have to apply it or change it as it is what it is.

EXT4 and ThunderBolt script
[Galaxy S I9000 General] bofh999:
youre talking nonsense - again if its in memory its lost doenst matter which filesystem you use

its true that write back can do (but its for a very short time it need to write)

i dont wanna go so far now to explain the hole thing step by step - just google for it if you wanna know the details.

theres also the other problem beside wrting caches is diskcache itself nad raid caches

thats why highend raid controllers have a battery pack - because they dont write instantly - they have a rw cache - depending on their config its quit possible to have couple gigabytes in their buffers

in difference to your read buffer writebacks arent there forever while its possible that a read buffer stays for years :)

and again another filesystem DONT HELP YOU THERE

if its in ram - its gone

if its not in ram its on disk

the problem with non jounaling filesystems are open files not files in memory

btw even android dont caches in ram - if it would

- we would ran outta ram quickly

- devices would be way faster

but if you really wanna tweak - we could replace the ext4/rfs with an ramdisk - should be possible on android to

hell i even tried a mysql instance running on a ram drive - hell thats awesome

- of course you dont sleep much if it would be an production system lol

btw youre not a better person to know whats going on - its obiviouse youre trashtalking - read some sentence somwhere in the net and try to be an expert - your saing that linux delay write to ram and wait ages bevore commiting them is absolute nonsense so the most of what youre saying is

im sorry to be so harsh but i cant stand those people wasting my time

you got no idea what im doing - you dont know my job description and you dont even have an idea how long i make my job so dont think you know something about me or my knowlege

EDIT: bootloop?????

wtf youre talking about ? do you know yourself what youre doing?

the rfs is on the data partition not on the bootpartition

on linux and android bootpartitions are mounted READ ONLY - nonsese for journaling here btw

all other system related partitions are ext4 by default - /system is ext4 with ro (hmm waste for ext4)

only /mnt/sdcard is mounted vfat

at least it is on 2.3.5 stock firmware
[Galaxy S I9000 General] elhennig:

Ignoring the argument going on, I just want to share my experience with rfs. I'm running stock 2.3.3(DDJV9 - Indian). And my god does it lag!?

I can bake three cakes while my phone boots, get a good nap before facebook opens and penguins till my contacts open.

As someone mentioned before, if you have rss readers like pulse or even foursquare or bbc news, your sgs will go into depression and reboot itself. That's what happening to my phone. Even after a clean hard reset, the phone lags a lot.

I fail to see why such a powerful phone can't even open messages or contacts without lag. My SGS is not at all smooth.
[Galaxy S I9000 General] jonny_ftm:
I tried most ROMs till 2.3.4, and my SGS always had lag. Of course, if you talk just after a flash, it is smooth. After few days, it gets again so laggy.

I also have an SGS2, and going back from the 2 to the 1, is pain in the a** in terms of lag

I don't have many apps installed, less then 20, few widgets too (3)

You know, on early 2.1 roms, the same people you hear now saying it doesn't lag, were screaming their SGS doesn't lag. Either they report just after a flash, or they just compare their phone to an old windows 3.11

[Galaxy S I9000 General] adriankim1984:
best for me is to use Odexed ROM with EXT4.. performance and battery problem solved. paired with Semaphore or Talon kernel.

On Semaphore App

Go to governors and select ondemand

Go to schedulers and select simple i/o ------ tested and this resulted best for me

Go to low memory killer and select 32mb -multitasking

Go to sd-card read ahead and select 256kb -64kb-best

There is nothing u can ask more except for a good theme. :-)
[General Questions and Answers] mindwalkr:
Hey guys,

I'm trying out a few launchers (Launcher Pro in this case) and I was wondering.. Ultimately if you go for a new launcher, you'll always have the stock launcher installed as well.

What happens with the widgets that are on the launcher that's currently not being used ? Do they still update and take their toll on the system ? Or should you remove all the widgets from all the launchers that are currently not in use ? This is a bit of a pain as you have to set it all up again if you wake up one day feeling like switching launchers.

Thanks for any hints :)
[General Questions and Answers] Natalie_s:
hmmm

:eek:never heard of thet
[General Questions and Answers] mindwalkr:
For example, some widgets are programmed to only do the background updates if the widget "has been installed". By this it means, deployed in a launcher. Now if it's on the launcher that is not currently in used, it may still be doing the updates. Dunno...
[General Questions and Answers] papo:
yes...stupid behaviour..how to get around this? found anything?
[General Questions and Answers] Dirk:
As far as i can tell, they are not updating if the launcher isn't the one being used.

Interesting avenue of thought though. You could use a task manager to see if the idle Launcher or Widget app were doing any work, if you want to check for yourself.
[General Questions and Answers] mindwalkr:
well in the meanwhile I resorted to the stock launcher and removed all others so I never got to dig into it too much. But I might just for the sake of curiosity! Battery Monitor Widget writes a history file. It's easy to download it, place it in a launcher, and start using the other launcher without the battery widget. Then after a while check the history file and see if it's been updated lately...

However from an API point of view I'm a complete n00b so I don't know if the Android platform is stopping widgets on unused launchers or if the widgets have to contain code themselves to query if they are in the active launcher and if so... run. This would mean that some widgets might behave as expected and others not.. :)

I've had TB since march and just today I haven't been able to receive text messages. I can send, get email and make phone calls. From what I've read, this has been a problem. I guess it just caught up with me. Is there a fix? Will rooting help?

Ok so I had to do a factory reset and I can now again receive texts. But this is a temporary fix. According to Verizon, there is a bug or glitch in the build version 1.3. They claim they are aware of this problem and have an open ticket. Don't know when the fix will be completed.

In the world where everyone is looking up to gingerbread, I am putting Polaris Office (of Galaxy S2). It has much more features than thinkfree plus working on I9003.

Pre-requisites:

1. Your phone should be rooted

How to install:

Method 1:

1. Extract the files from compressed file

2. Copy apk from app to /system/app

3. Copy files from lib folder to /system/lib

Method 2:

1. Extract all files in a folder (i use winrar; hence extract to <folder name>)

2. Run the batch file (it will ask for su permission. Ensure to allow that)

Backup your data, i wont be responsible for any loss
