Red Hat DIRECTORY SERVER 8.1 - DEPLOYMENT Deployment Manual page 83

Evaluating the Costs of Indexing
To run more efficiently, the directory service places as many index files in memory as possible. Index
files use memory out of the pool available depending upon the database cache size. A large number
of index files requires a larger database cache.
• Index files take time to create.
Although index files save time during searches, maintaining unnecessary indexes can waste time.
Be certain to maintain only the files needed by the client applications using the directory service.
