DIRECTORY SERVICES

Extended Directory Catalog size
Since 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. Don't replicate the database to Notes clients and use as few replicas on servers as feasible.
