ldapi:/// is based on UNIX domain sockets, not UDP. I think the major benefit
of ldapi:/// could be that you can use conventional UNIX permissions (which
are fast) to control access to the directory so you do not need to use ACLs
(which are slow) at all. Also, there is no possibility of a remote break-in
or DoS using ldapi:///.

Not seeing a big performance difference between ldap:/// and ldapi:/// means
that not the network bandwidth is the bottleneck in your configuration.
