On a related note there are filesystems that handle many
files/directories very quickly. They use alternate tree data structures
that behave quicker. ReiserFS is one of them. I believe XFS does quite
well too. FreeBSD should have adapted XFS in addition to ZFS. ZFS is a
resource monster. Shame, really. XFS is freely available in Linux for a
number of years. Hammer, the new FS for FreeBSDs is available for
DragonflyBSD.
