Guest darky4e Posted January 23, 2011 Report Posted January 23, 2011 (edited) As i know the Galaxy S lagfix is based on filesystem conversion! They converted /system /data and /cache partition to ext2/3/4! Its faster! Maybe we can do the same! Previously a had i5700 and we was able to convert all the filesystem to ext4! Here are the files that contain the scripts! Maybe some dev could start to work on it! I have only basic bash/awk scripting experience! I think its enough when we correct the partition codes on the code and it will work! The zip contains system to ext4,data/cache to ext2,e2fchk,xbin and ext to rfs scripts! Or we can start a new script from scratch based on these scripts,but i think it isnt necessary! And we will need to add to the kernels some ext support I think we can start with ext2 its faster then ext4 but no jounaling! But ext4 is faster at bigger filesize as i know http://www.mediafire.com/?qpw233q9m0tsbp2 Here is a zip what convert all the partition to ext2! DO NOT TRY TO FLASH IT!!!! 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 http://www.mediafire.com/?qpw233q9m0tsbp2 Edited January 23, 2011 by darky4e

Guest lavan Posted January 24, 2011 Report Posted January 24, 2011 where is the link ? :lol: Yes most of the samsung android mobiles are usin RFS as file system..whihc is indeed very very slow compared to EXT2 n EXT3 For eg There is EXT Mod for samsun spica i5700 http://forum.samdroid.net/f38/i-o-performa...iscussion-2588/
Guest fonix232 Posted January 24, 2011 Report Posted January 24, 2011 YAFFS2 is a lot better for phones than Ext2/4!
Guest MrPuddington Posted January 24, 2011 Report Posted January 24, 2011 (edited) YAFFS2 is a lot better for phones than Ext2/4! It depends on organisation of the flash memory. If it has a load balancing controller, ext2 would be just fine. I am not sure whether the ZTE Blade has one, but my guess is that the designer cut a corner... Not having any kind of load balancing would put the flash memory at risk of failing rather soon. So that is not something I would like to try. Edited January 24, 2011 by MrPuddington
Guest darky4e Posted January 24, 2011 Report Posted January 24, 2011 (edited) /dev/block/mtdblock5 /system yaffs2 ro,relatime 0 0 /dev/block/mtdblock6 /data yaffs2 rw,nosuid,nodev,relatime 0 0 /dev/block/mtdblock7 /persist yaffs2 rw,nosuid,nodev,relatime 0 0 tmpfs /sqlite_stmt_journals tmpfs rw,relatime,size=4096k 0 0 tmpfs /mnt/asec tmpfs rw,relatime,mode=755,gid=1000 0 0 /dev/block/mtdblock4 /cache yaffs2 rw,nosuid,nodev,relatime 0 0 /dev/block/mmcblk0p2 /system/sd ext2 rw,noatime,nodiratime,errors=continue 0 0 We could give a try with ext2,or ext4 without journal! They are really fast. The hungarian zip is repartition our system so maybe if i fail it can help me to save the blade. What kernel modification needed to work whit this? Our quadrant score for I/O is very low! It means quadrant need a lot of time to read and write it! Yaffs2 vs ext2 Edited January 24, 2011 by darky4e
