Simo,

If what goes over the wire is 100 separate renames, then yes, it will
be slower, as it will be 100 separate transactions. If what goes over
the wire is one rename of a subtree then we should be able to do it in
a single pass.

ldb+tdb has just about no knowledge of 'trees', so I don't really know
what you mean by a 'reference outside the tree'. Certainly a reference
between different ldap subtrees is no different then references within
some arbitrary subtree.

Maybe you mean references between ldap servers?

I don't understand this. Can you give a more specific example?
