Subject: Formatting JFFS2 Flash


	I have a PPC 860T custom board with kernel
2.4.4-2001-11-11-denx and rtai-24.1.4-2-denx. I have
a JFFS2 filesystem on 14MB Flash. I make an initial
filesystem with the "mkfs.jffs2" utility, and the first time
I copy a 1MB file into it, it takes about 2 minutes, and
then on it takes 10 seconds to copy into it the same file.
I suppose that the first time, jffs2 is doing something like
"formatting" the flash.
Does anybody out there know how to do this "formatting"
in a smarter way?

				Thank you
