Monitoring and Improving Performance
Fragmentation
Performance can suffer if your database file is excessively fragmented. This is disk fragmentation and it becomes more important as your database increases in size.
The database server determines the number of file fragments in each dbspace when you start a database on Windows NT/2000/XP. The server displays the following information in the server message window when the number of fragments is greater than one:
Database file "mydatabase.db" consists of nnn fragments
You can also obtain the number of database file fragments using the DBFileFragments database property.
For more information, see Database-level properties.
To eliminate file fragmentation problems
Put the database on a disk partition by itself.
Periodically run one of the available Windows disk defragmentation utilities.
