the W/R performance of my wear-leveling unit

Hi,

I've compared the current WL unit algorithm with
my new WL unit one on the W/R time.

modprobe nandsim + ubi + ubifs.
And then copy a file (9338201 Bytes) to

##time for i in seq 1 20; do sudo dd if=~/tmp/file of=/mnt/ubifs/file count=1024&> /dev/null; sync; done

in the first time. the time of currenty algorithm and mine is as following:

current UBI gives:

real 0m3.145s
user 0m0.124s
sys 0m0.700s

mine:
real 0m2.539s
user 0m0.140s
sys 0m0.772s

some more experiment share:

yours Sincerely,
