improve P500 I/O score - Optimus One, P500, V General

Guys, Joeseph Mother @ samdroid just show us his crazy I/O score (10 times faster than our speed now - 4xxx (without OC, i guess) compare to ~400 as our P500 OCed to 786MHz using Darktremor a2sd @ext4)

His secret as below:
"To improve the i/o by using ext2, the easiest way is to extract your ramdisk and edit the init.rc, by mounting /data on mmcblk0p2 (your sd card) you can easily make it ext2,3,4,xfs,jfs, whatever you want using gparted
To extract/repack your ramdisk, you can follow the instructions here, to enable booting with /data on sd as ext2, just change the line in your init.rc with [email protected] to this: mount ext2 /dev/block/mmcblk0p2 /data nosuid nodev noatime nodiratime"
I'm just new to Android so hoping that some of you guys can successfully done the same trick and show us all the step-by-step instruction later.
TIA

is this meant for all ROMS? or has specifics for CM only?

One word: Stagefright. You can turn it on on build.prop and have amazing Quadrant scores. Real life performance change? I doubt it.
Also, I don't think "booting with data on the sd card" is a good idea. Read and write speeds on SD cards are significantly lower than reading directly from internal memory.
Just a hunch, based on real life data

rom independence i think.
With stage fright enable our I/O still at max 400 compare to his 4K !!!! AFAIK H/W, JIT, Stage fright or any know tips did not improve I/O as this much!
Guys, pls don't mess with the final score, just focus on the I/O scores, his phone no OC.

It can be done with Firerat's a2sd script for CyanogenMod aswell, and it's a lot easier than changing your ramdisk. Here's My Quadrant score with ext2.

you mean this? http://forum.xda-developers.com/showthread.php?t=655256 this script NOT universal, i guess. DO you have a proper one for P500 or a TUT for this will be AWESOME.
Thanks anyway for keeping up our hope hehehe
P/S: just found out this http://forum.cyanogenmod.com/topic/...2010-10-22-v135-resolves-mount-issues-i-hope/ but still don't know how to make it working...

As long as the rom you're using supports init.d scripts and has the sd-ext mount point just steal the mountsd and userinit scripts from any cm7 rom and then run fr's script and you should be golden. You might run in to issues with e2fsck (I did originally) but you should be able to grab that from a rom with the same CPU if you find one with e2fs tools. If I get some spare time I might look into making it a bit more portable, but some dependencies are gonna be hard to get round.
<edit>I was thinking of the second one you mentioned</edit>

This is the same as the data2sd mod, just worked into the kernel for ease of use. It's fast & stable, but over time may kill your sd card, but they're fairly cheap, so that doesn't bother me. What really surprises me is that when you convert the nand to ext2 & pull the battery, you reboot to a wall of force closes, I've pulled the battery 10 times with this and haven't had a single fc. This works very well with cm7, I did it with that rom and got 1950 at 806mhz.

I really don't know why you would want to do this... what if the SD card fails to transfer some important libraries while booting up?... ur p500 wl jus crash

Booting 2 different roms is what I need!

OMG 1950 how can i sleep tonight? hehehe keep dreaming myself...
Guys, not because of the score but i'm a PC overclocker so always wanna tune up everything @ limit. Learning more thing was great, i guess! But as a noob @ android so my journey still at the very first beginning!
And about the two rom solution, JUST fantastic... so we can have two rom, one as a phone and one for tune up maximum!!!! Keep it up...

Just thought I'd show off, this still works well, it's a 1 line change in init.rc...this is on cm7 beta 3.1, overclocked to 806mhz..

change
mount yaffs2 [email protected] /data nosuid nodev
to
mount ext2 /dev/block/mmcblk0p2 /data nosuid nodev noatime nodiratime
Just make sure you have an ext2 partition on your sd card.

Dude. First of all that score is insane ) Second of all, please, for us who are at the beginning of their android experience but still want to push their phone to the limit. Please, let us know EXACTLY what you do. For example I don't know where the init.rc file is (read the net that it's in /system/core but core folder does not exist for me or I simply can't see it) also how do you actually edit the file, with what software? How exactly can you tell if you have an ext2 partition on your sdcard, and if you don't, how do you create it? Please, write the exact steps, no links to other threads (cuz it's really annoying and gets harder to follow), just the steps to all that you said in your post. Thanks in advance!
