UBIFS performance

[Brijesh Singh]

Hi,
  I am testing UBIFS and JFFS2 performance on OneNand with iozone utility. 
Interestingly, random read / write performance are slightly better than 
sequential read / write.
These results are consistent across multiple versions. And consistent with 
all different record length sizes.

Correct me if I am wrong, but shouldn't sequential read/write fair better 
than random read/write? Is this expected behavior? If yes,why?

Thanks and Regards,
Brijesh
