What is your usage of this LDAP-server? Unix-login with SecureShell?
If you do, make shure you have NSCD (Naming Service Cache Daemon)
with apropriate settings. You don't want a 'ls -l' to run a ldap-query
for get-pwent etc etc.

It might be a good idea to run your slapd with more debug/logging to see
what type queries are being run and analyze the logs.
