How to Improve Directory Search Performance

To improve the performance of directory searches for users, organization, and groups, do the following tasks:

Index the attributes that administrators can specify in search queries.
Override the default directory timeout setting by specifying values for the timeout search parameters in a directory configuration file (directory.xml).
Tune the user directory. See the documentation for the database that you are using.

Configure database-specific options in the ODBC data source. For more information, see the documentation for the data source.
