XFs's claim to fame is:
* hashed directory lookups, making namei() on large directories more
efficient (but only on large directories).
* log file system .. fast startup after a crash verses the fsck you
have to do with ffs. So if your SGI box crashes a lot :-) ... just
kidding.
* 'real time' extensions in access and data layout. Useful for video
editing, not useful for anything else.
* Ability to expand the size of an xfs filesystem partition via lfs
without having to dump/restore. A useful feature.
The file creation/deletion/access rate is about the same. However,
BSD's namei() and general filesystem buffer cache implementation is a
whole lot better then SGI's, as are BSD's (4.4's) kernel locking
mechanisms.
