I erased the whole flash. I copied a 500KB file to the
NAND flash. Then I copied the file from the NAND flash
to the same directory with different name. This means
read and write operation on empty flash. With the old
version it takes around 2 seconds, with the new
version it takes more than 12 seconds (I am using the
ZLIB for compression).
I wish I had the version iformation of the old MTD and
JFFS2, but I do not (It should be from 4 month ago).
