Use the connection pool ---------- If OLEDBConnection, the connection pool is automatically handled by the provider ---------- If it is the SQLConnection class, the connection pool is implicitly managed but can also manage itself. Specify pooling = true in the connection string; connection life = 5; // Declaration cycle min pool size = 1; // minimum connection number Max pool size = 50; // maximum connection number
