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). --vahid > Think would be nice to come with digits. > Try to profile it. __________________________________ Do you Yahoo!?
