I miss your point. Of course additional checks require additional
resources. Besides that OpenLDAP is certainly not the best LDAP
implementation available (but basically the only freely available).
Commercial directory servers scale to huge amounts of entries and
hit-rates.

BTW: if you write that the server *fails* to respond to request it
sounds more like a bug than a performance problem. Maybe you are using
an unstable OpenLDAP version ?

Exactly. It would be nice as an option (especially in enterprise
environments), but not as the only way to store defaults.
