Tuning
Use this information to improve IBM® Domino® server, Domino Web server, and messaging performance through the use of resource balancing and activity trends, Server.Load commands, advanced database properties, cluster statistics, and the Server Health Monitor.
Setting advanced database properties
Advanced database properties include performance optimization and compression features, as well as ways to manage usability features such as unread marks and soft deletions.
The database cache
To minimize delays that occur when users, servers, or API programs open and close databases on a server, each server maintains a database cache. When a database closes and there are no users or processes using the database, Domino® puts the database in the cache so it can close it quickly. The database remains in the cache until it's opened again or for about 15 to 20 minutes, whichever comes first. Databases in the cache can be opened quickly.
Controlling database size
Databases whose size is monitored and minimized show increased performance: database operations require less I/O and fewer CPU resources; view rebuilding and updating is quicker; and memory and disk space allocation is improved.

Controlling database size

Databases whose size is monitored and minimized show increased performance: database operations require less I/O and fewer CPU resources; view rebuilding and updating is quicker; and memory and disk space allocation is improved.

The maximum database size is 64GB on Microsoft™ Windows™ and UNIX™. Use the following methods to minimize and monitor the size of databases:

Compact databases
Set database size quotas to prevent databases from growing beyond a specified size
Delete inactive documents using the document archiving tool or using agents
Set database performance properties that also reduce database size
Use replication settings to limit the size of a replica by replicating to it only what's necessary
When limiting the contents of a replica, decrease the database purge interval to remove deletion stubs more often
Disable the default user activity recording in databases
Disable soft deletions in databases
