dunno, there's a lot of variables at play to make a suggestion.  but i
don't recall doing anything overlay special.  nslcd was one thing we
absolutely had to run, we tried to avoid it at first, but the lookups
across the enterprise crushed the server.  with nslcd running the ldap
server load is generally low.  we can spike it though with a
large/fast rsync or someother filer heavy action, but most of our
users cannot.

how many objects do you have in your tree?  are you storing more then
passwd/shadow/group info?
