Brief descriptions

• Fileop result:

Output is in Ops/sec

• mkdir: Create directories
• rmdir: Remove directories
• create: Create files (empty)
• read: Read files
• write: Write files. X^3 number files will be created (controled by faktor parameter).
• close: Close files
• stat: Read stat info
• access: Check permissions
• chmod: Change permissions
• readdir: Read directory entries
• link: Create links
• unlink: Remove links
• delete: Delete files

• In the relative data the
  • green and lightgreen values mean UBIFS is faster than the reference (at least 5%)
  • red and pink values mean UBIFS is slower than the reference (at least 5%)
  • black and gray values mean ratio is in 5% margin of error
  • lightgreen, pink and gray values are obsolete

The full descriptions of the tests and other resources about the benchmark are available on IOzone website.

Command line and settings

We used the following commands and settings to produce the results.

Mount

• UBIFS

flash_eraseall /dev/mtdX  # Only for clean fs
modprobe ubi mtd=X
ubimkvol -d 0 -n 0 -N ubifs -m # Only when flash_eraseall is executed
modprobe ubifs
mount -t ubifs ubi0:ubifs /mnt/mtdX

• JFFS2

flash_eraseall /dev/mtdX  # Only for clean fs
mount -t jffs2 /dev/mtdblockX /mnt/mtdX

• LOGFS

flash_eraseall /dev/mtdX  # Only for clean fs
mklogfs /dev/mtdX
mount -t logfs mtdX /mnt/mtdX
