Yes, I know. Is that better then JFFS2 on top of mtdblock device?

Still one must plan for the worst case and the worst case for me
was about 2 hours of mount time after I used ftp to transfer large file.
I suspect ftp was writing really small jffs2 nodes.
Disclaimer: that was about 2 years ago and jffs2 might have improved,
processor (ARM9) was not a speed demon either.
If you do that on your iPAQ (create large file with lots of small nodes)
and then cold boot it - would you be willing to wait for an hour for it to
become usable again?
I really hope UBI+UBIFS will overcome this problem. Still there is a concern
here since UBI scales linearly. Can somebody plz post UBI scan time for large
