Gents,
Here the basic performance measurements for JFFS2 and YAFFS2 as of
5/10/2006 are presented. The measurements were performed on the PNX4008
platform which is a 208 MHz CPU ARM926-based Philips board. The 2k page
flash is the real NAND flash (20MiB partition); the 512b flash is
nandsim (8 MB partition).
