As a follow-up on this one, I did the same measurements on the same 2k flash but w/ standard OOB layout and SW ECC. The results are below.
Write big file Write folder Mount

YAFFS2 | 96.4 s 67.1 s 0.8 s
JFFS2 w/o summary | 67.3 s 16.3 s 6.1 s
JFFS2 w/ summary | 66.8 s 16.2 s 0.5 s
I guess that the *real big difference* in "Write folder" test results might be related to the MTD layer... which I'll try to figure out soon.
