Just update GMaps and others apps and I did not realize any difference!How is it when installing apps?
Which Rom?which SD?how many apps installed?For me it seems really smoth with 40data2ext4. My goal is have a FS that can support a lot of applications without lag on startup or loading icons, low battery consuption and no data corruption. Until now I think I got my goal. My quadrant score average is ~1500 with I/O of ~650 but this does not mean nothing for me! I dont have lags on thing like "super user permissions", "click buttons", playing games or scrolling screen.

yes just compared with unjournaled ext2The lower the overhead the better so from what you said nand has a larger overhead. I wonder why the database performance is degraded so much for writes, that imo must be the reason for any lags it is the only time nand does better.
I wonder what version of sqlite android uses because I remember reading something about efficiency improvements in newer versions. I suppose the issue is as usual cross compilation and android may use a modified version of sqlite.
Woow!!!211apps are terrific!As I said on my post a page ago:
- Oxygen 1.0.3
- 40data2ext4 script
- uSD class 6 "Turbo" ( I dont know what that Turbo mean), 1 fat32 and 1 ext4
- 211 apps.
i put it in RAM - just to compare, and get only 2900 overallInteresting but way above my head to figure out the cause for the huge database write speed loss.
Just an fyi to my previous post, android uses sqlite 3.6.22, the current sqlite version is 3.7.4 so android is some way behind. I expect there have been performance improvements since 3.6.22 the problem is how to install a newer version and will it break the android sqlite lib? I personally think it might break things otherwise google would have included it in gingerbread I am sure.
I didnt tested on any HD sense based ROM but I think should work the same way. All I did was: 1- flashed Oxygen ROM, 2- before reboot (from recovery): 2a- replace my busybox with the new one, 2b- remove A2SD script and replace with 40data2ext4 script, 2c- set permissions, 2d- create the folder /system/data_internal. That`s it! 3- reboot.Woow!!!211apps are terrific!
Can you explain me how set it up on sense hd based Rom?

It's required that Rom is only on nand?

The overhead would fit to my assumption that the reason the lags are better with btrfs is the filesystem. So its not the ACTUAL write speed to /data/data that matters but it's the difference between ext4 journal and btrfs copy on write.i moved to compare
/data/data/com.Peaceman.Benchmark
on the fly to nand and made a symlink to the directory from /data/data/ to the directory in nand
so my database writes got from 6 to 52/s
and overal to 2487 from 2373
but the filewrite overhead is now (with in nand not btrfs) 6.66 ms (from 0.72ms), could that be a reason for lags?
mattiadj. I said in the thread, i said it in ownheres thread and i said it per PM. Just WAIT a bit for ROMs that have everything ready. Explaining the installation for every user just takes time.Woow!!!211apps are terrific!

this could mess up the permission of the files on the external but im not sure....In a working data2ext rom if i copy all files from ext partition and then make again the partition formated at btrfs,
add the script with the right permissions and copy back the files to the new btrfs partition will it work?
If you think that's doable then i'll try it and let you know what happened!this could mess up the permission of the files on the external but im not sure....
Give it a try.....If you think that's doable then i'll try it and let you know what happened!
I'll take a nandroid first of course just in case, that's why we have it after all.
this works only in an *nix like enviromentthis could mess up the permission of the files on the external but im not sure....
