sorry for keeping u guys waiting... and thx for u all
but i've to take care of my dog 1st, and need some time to prepare screen dumps, as well as some important issues

well, b4 i show u what has to be done, i would like to say that:

1/. dont expect too much, it's a number actually, but it really rocks
2/. it is not by oc
3/. it's 100% original stock firmware and not modified since i bought it
4/. u may be stunned for not using ext3/4
5/. i think it can be applied to many firmware, although performance may vary
6/. i'll append it to my 1st post

thx

So it is a hack made only for benchmark?

I'm curious! I'm in! If this is adaptable to other firmwares it should be nice!

op should be working for samsung

EDIT: 8 aug 2250HKT

ok, here's how:
- create an empty file with dd (i chose -b 4096 -m 1)
- mount it to loopx and format it with ext2 (busybox)
- create mount points and create links, eg
mount -o rw,noatime,nodiratime /dev/loop0 /dbdata/dbdataimage
then mv files and folders to /dbdata/dbdatimage
so, instead of reading /dbdata/databases/com.1.2.3, it will be linked to /dbdata/dbdataimage/databases/com.1.2.3
- finally write a script to mount them on boot by replacing playlogos1

simply speaking, is to run on an ext2 file block in rfs, and that's all for the trick!!

WARNING:
- i did it for /cache, /dbdata and /data only
- empty files, folders, and sym links will be deleted by the system under /cache
- dont reboot the phone when u've temporarily moved /dbdata/databases to a slow partition like /data

personally, i moved /data/data and /data/dalvik-cache to /dbdata and moved browser and market cache files to /cache

PS E&OE
enjoy!

Wow, need someone to explain this a little more

Thanks for sharing the tip

Haha, nice idea! If you can't reformat the internal SD card, just make a filesystem inside it and run off that!

It should actually be pretty easy to make into a script that anybody can just run.

So, if we run with mimocan's kernel would this be even faster with an ext4 block?

I don't know if this is even possible, and I'm sadly a windows user so I won't be attempting this fix until there are step by step instructions or a script to get it done.

Nice work though OP!

The application data partition is formatted using a samsung filesystem based on FAT32. This filesystem seems to be very slow. (not sure why, filesystem shouldn't make that much difference - the filesystem must be buggy)

What mimocans fix does is create an EXT3/4 partition on your external SD card and then creates a symlink from the data folder to the new data folder on the external SD card. This means that if your external SD card is fast enough, you get a faster system.

What ykk_five's fix appears to do (I haven't tried it) is create a normal file inside the normal data partition. He then sets up a virtual device inside that file, and formats that device as EXT2. Basically a virtual EXT2 filesystem inside samsungs FAT32 filesystem. He then does the same as mimocan, and creates a symlink from the data folder, to the data folder inside his virtual device.

This data partition runs off the internal SD card and should be faster than an external one.

So basically, this is a much nicer lagfix than mimocan's one if it works correctly!

Yeah, should be even faster with EXT4

MOUSEY · Aug 8, 2010

Interesting !

Looks promising, let me get the latest ROM and see if my linux knowledge can pull this one off or turned mine into a brick...

android53 · Aug 8, 2010

Really? I heard of people getting 2k+ scores on the vibrant by using a mimocan like hack that uses ext2 instead of ext4. Ext2 should be faster then 4 but more prone to data loss

furstrated · Aug 8, 2010

i hope a tutorial is forthcoming.
i only got the general idea, and thats because i recognized the abbr RFS.

Shinili · Aug 8, 2010

Just one question.... why isnt Samsung using ext2/3/4?
I mean... they should know about the performance-boost Oo
Or is that hard to let, for example, kies format the phones internal sd card while or before flashing? Oo

And since Galaxy S owner loves benchmark:

I hope that everything will be fixed with froyo..or i'll be back with my N1 that is way faster (not in 3D of course..)

I hope someone write a step by step tutorial for all users....

that's a pretty ridiculous benchmark for eclair

GSeeker · Aug 8, 2010

waiting for a simple solution i am no linux expert. thanks op!

Sent from my GT-I9000

thats what I was thinking this score is with the original kernal.
What would be the benchmark score with the latest kernal and jit.
Most people didn't even notice that

sunwee · Aug 8, 2010

Damn...why wouldn't samsung use ext2/3/4 as the default file system. Then we wouldn't be talking about lag here
