Avoid Creating Entries Under the cn=config

This section covers some common performance-related tips and concepts to remember.

3.1.Avoid Creating Entries Under the cn=config Entry in the dse.ldif File

The cn=config entry in the simple, flat dse.ldif configuration file is not stored in the same highly scalable database as regular entries. As a result, if many entries, particularly entries that are likely to be updated frequently, are stored under cn=config, performance will probably suffer.

Although Red Hat recommends that simple user entries not be stored under cn=config for performance reasons, it can be useful to store special user entries such as the Directory Manager entry or replication manager (supplier bind DN) entry under cn=config since this centralizes configuration information.
