Syncrepl is supposed to be the eventual replacement for slurpd, since
slurpd isn't maintained overall. There are a number of advantages to
syncrepl over slurpd long term. Faster updates (we currently have an
issue with the speed at which slurpd replicates, so we give a few select
systems access to the master) is one on our list. Another interesting
capability with syncrepl is that you can give a specific replica its own
access rule, which means that you can replicate not only subtrees, but
only certain entries in subtrees.
