Thanks for your quick respone.

Then How can I figure out whether the files are defragmented? Because the file system's
read/write speed is greatly slow down ( about 8-10 times slower in extreme cases).
Can you suggest a tool|package to report file systems' defragment percentage? I tried a beta version
oodcmd tool which reports both block defragment percentage and inode defragment percentage, are those enough?
or there are still more defragment characteristics? I'm a little hesitate to use the commercial oodcmd tool
since it can only work when file systems are unmounted and idle.. sigh..
