I too am suffering from this very slow JFFS2 problem.
It is especially bad for NAND flash.

I modified the fs/jffs2/Makefile to use fs/jffs2/jffs2_nand_1pass.c
instead of jffs2_1pass.c, but that would not build.

I eventually fixed that by quite large changes, but it still ran
very slowly despite reading larger chunks of NAND.

Has anyone out there fixed this problem?
