It's not about feelings. I compared with some measurements I had from before, creating and copying files and it is indeed faster, not by much, but faster. I would like to test it better but I have only one device. what I had not timed but I 'feel' is improved is starting of heavy apps, like maps and mypaint.

You may not have noticed any file corruption thusfar, but nevertheless, the kernel-power "shipped" ext4 doesn't have the patch from 2.6.30 which prevents it from happening. Hopefully, pali will include my diff in kernel-power48 but in the meantime you can compile your own with it (I have).

PS I also included all of the other ext4 "cherry-picks" for 2.6.28 that hadn't made it into kernel-power thusfar, namely the May 2009 git commits labelled "for-stable-2.6.28". This means that issues like this one won't occur either (albeit, that one's less likely to occur on an N900 - I'm not aware of anyone who works with 10GiB files in /home on a regular basis - but you never know..)

@Tigerite
Since pali seem to have not compiled your patch would you mind providing to us a temporary binary (for those who don't use linux PC's and not into kernel compiling)

Is there any kind of guide on converting mydocs to ext3/4?

A guide that deals with all the camera saving, mountng at boot time ramifications that is?

any simple tutorial to mount ext4 as home , formatted , to ext4 , moved home to other partition
but i'm stucked

Alecsandru, search is your friend:

(True, I searched for "home ext3" but a small update to the instructions is an easy exercise for the reader. BTW the last one also deals with the camera application which apparently some people had problems with.)

FWIW, I've fiddled with ext4 myself and it worked pretty well but the next BackupMenu restore reformatted opt back to ext3. I did not feel like fiddling with BackupMenu so I left it at that. ext4 might be faster but at a price: it achieves speed mostly by lazy writes which is not always safe if you unexpectedly reboot.

I/ve formatted home to ext4 with gparted ,flashed firmware(now home is in nand) , now how to proceed to use the new ext4 as home ? installed kernel 52 ,leafpad and rootsh

evrika....dam it's fast , but I have some problems with fapman and advanced clock plugin , fapman tells me that I have no notwork connection , but download and install softwares , the problem is that I can't update catalogs with fapman

any procedure to make this system fast ??????
