My 7 years old laptop could be classified as the opposite of super
computer:). As an average home user, I don't benchmark filesystems, my
experience is purly subjective. Still, I would appreciate a filesystem
that can:

1) journaling. the long ext2 fsck is too painful.
2) performs well on a lots of small files, maildir and extrace linux
kernel source for example. 
3) performs well on large files, to me, large means several G, since XFS
appears define large in astronomical number, it should be happy with my
4) online defragment. there are files under thunderbird and firefox
profile directory keep been modified. I expect better web browsing
responsiveness if those files been defrag regularly.

I am using ext4 now, works fine so far, it will be great if ext4 have
online defragment, though, I shall put xfs on the list when need install
an OS or get a new hard disk next time.
