By default, if no database server is found during a connection attempt, and a database file, database name, or the START connection
parameter is specified, then a personal database server is started on the same computer. You can turn this behavior off by
setting the AutoStart (ASTART) connection parameter to NO in the connection string. The database server is not started automatically
if the CommLinks (LINKS) parameter includes TCPIP.
To improve query performance for databases that are started automatically, start the database as soon as possible, even if
users are not connecting right away. This allows the cache to warm before queries are executed against the database. See Using cache warming.
