First you should look into "nscd". This caches any nss queries which will mean
that you will hit your directory less.
Secondly you need to get your directory indexing correct, here are the appropriate
lines from my slapd.conf:
index cn,sn,givenname,mail pres,eq,approx,sub
index ou,o,c,dc pres,eq
index uid,uidnumber,gidnumber,iphostnumber pres,eq
index default none
These should give you excelent performance for your environment.
