That is very true.
It is really designed for dumping whole filesystems (or at least,
large parts of them).
For dumping small subtrees, I'd be looking at using something else.
That was one of the 1st things I noticed when looking at the xfsdump
code on IRIX a while back, was all the scans it does and how for a subtree
it will do another scan and prune the data - i.e. implemented
like an afterthought :)
It is built around bulkstat which walks all the inodes which is great
for dumping them all out.
But if you want a small directory walk then you need something else IMHO.
