I/O performance boost: convert all to EXT2 -> in one zip !!

[luismaf]

ONLY FOR FROZEN ECLAIR, FROYO [AOSP], OR CYANOGEN

this upgrade is safe, but do this at your own risk

I made a zip that's convert all to ext2, incresing dramatically the I/O performance of your spica

What could you expect from this mod?

• Faster boot
• Faster application start(If they are stored on the internal memory)
• Faster loading of contacts/messages/pictures/everything stored on internal memory
• Higher quadrant score

What does it do?

• verify the sd free space (if it's insufficient, abort the process)
• backup /system and /data
• convert /system, /data and /cache, from RFS/EXT2/EXT4 to EXT2.
• make a quick verify of the filesystem in /system and /data
• install fsckdata on boot (/etc/init.d/) essential to prevent derailing our fast EXT2
• wipe dalvik-cache

How to install it?

1. Copy the zip to the sd card
2. Boot in recovery console
3. Go to "apply any zip from SD" and then select this zip.
4. Wait a few minutes and enjoy!

Did it work correctly?

Go to the root directory of the SD card, you will find 5 files with ".log" extension.

Ext2 will make your system very fast: i reach 696 points in quadrant (1200-1300 in I/O)

You will need at least 100MB-150MB free in sdcard, if you haven't enough space on SD card, the update will stop, and the system will be changeless

The zip also install fsckdata (thanks ch33kybutt!!), make a fast check on your filesystem and wipe dalvik/cache (please, don't worry when you see "deleting files..")

Ext2 is faster than ext4, but has no journaling, then you will need get installed fsckdata to check filesystem on every boot.

If you install before update to 7.5 (for example) you will need to install fsckdat.zip again.

The conversion takes about 5 to 10 minutes, please do not stop under any circumstances: go for a coffee!

This modification is compatible with the previous I/O improvement (system to ext2, data to ext4): you can upgrade with this zip


I hope it will be useful for you, and make your spica very fast (and also solve your ext4 problems in cyanogen)

"install fsckdata on boot (/etc/init.d/) essential to prevent derailing our fast EXT2 "

does this run fsck on EVERY boot?

thanks for the scripts... i was a bit put off by all the different steps, but this is all in one solution.. thanks

Yes, it does.. is highly recommended to prevent data loss. EXT2 it's realy fast but doesn't have journaling (basicaly, a record of every change in filesystem), so (for example) if you remove the battery while it's copying a file, this file will be corrupt.. here comes fsckdata and repair the file In this hypothetical case, the boot will take longer than normal, but it is not common, otherwise, it will boot faster than ext4 / rfs

@luismaf, just FYI. In k/criminal.r6, /xbin will be replaced with swap partition. This will affect fsckdata which uses busybox at /xbin/sh. You might want to modify it to instead use /sbin/ash.

ch33kybutt, thanks for the info! Now I get to work

That modification reverted back atm.

working great so far, I'm testing Leshak's 8.5 build and I definitely feel the boost. I've used ext2/4 in the past but always ran into trouble with new kernels but what the heck I know how to get out of trouble by now . I wonder how this will go when upgrading which is where I usually get in trouble but so far is looking good. Great Job!!

slds,

Thanks AndroidGT, so far there is no problems with upgrades. Just remember install ch33kybutt's fsckdata.zip (or reinstall my zip) after upgrade.

thanks for the tip, I'll take that into consideration when upgrade time comes.

Is there an undo? And do I have to wipe dalvik after install?
