There are plenty of instances in which moving it to a cache area may
well improve performance. For example if you have several terabytes of
cheap storage, but a nice U360 RAID-0 as a cache area. Of course the
move will end up being a byte by byte copy anyway, since you can't just
re-link the inode accross filesystems, but still.
