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,
