CONFIGURING

Extended directory catalog size
Because the extended directory catalog contains the views that are in a standard Domino® Directory and combines multiple Domino directories into one database, it typically is very large. If you aggregate all fields as recommended, an extended directory catalog is about the size of all the aggregated Domino directories combined. Do not replicate the database to Notes® clients, and use as few replicas on servers as feasible.
