Yes, disappearing files could be annoying.
Has anyone characterized the performance of the JFFS* file-systems over
time? Our initial tests indicated that JFFS2 was faster than JFFS. After
using the JFFS2 file-system and maintaining a relatively consistent
utilization there was a 4X increase in the time required to complete a mount
operation. Is this expected? Is there a worse case? See below for some
measurements.
JFFS/JFFS2 Mount Performance (38% usage, fresh install):
JFFS real 16.164
user 0.01
sys 16.14
JFFS2 real 6.47
user 0.01
sys 6.45
After being used, usage = 41%:
JFFS2 real 1m3.583 (4X increase)
