Notification Services uses a quantum clock to schedule rule firings. If the Notification Services engine that runs the application was down, or if the workload is causing the application to fall behind, the quantum clock can fall behind the real-time clock. This means that Notification Services falls behind on maintaining the running subscription rules.
Quantum limits ensure that the application does not fall too far behind the real-time clock, helping to ensure that newer data is processed in a timely manner.
If you use the Application(Instance,String) constructor, the default value is 30 quanta, which is 30 minutes, assuming a default QuantumDuration value of 1 minute. If you use the default constructor, you must set this property.
0 indicates no subscription quantum limit. No subscription rule firings are skipped.

The following examples show how to set all application execution settings, including the subscription quantum limit:
// Define application execution settings
myApplication.QuantumDuration = new TimeSpan(0, 0, 15);
myApplication.PerformanceQueryInterval = new TimeSpan(0, 0, 5);
myApplication.SubscriptionQuantumLimit = 1;
myApplication.ChronicleQuantumLimit = 1;
myApplication.VacuumRetentionAge = new TimeSpan(0, 0, 1);
myApplication.LogBeforeDeliveryAttempts = false;
myApplication.LogNotificationText = false;
myApplication.LogStatusInfo = false;
myApplication.EventThrottle = 500;
myApplication.NotificationThrottle = 500;
myApplication.SubscriptionThrottle = 500;
myApplication.ProcessEventsInOrder = false;
' Define application execution settings
myApplication.QuantumDuration = New TimeSpan(0, 0, 15)
myApplication.PerformanceQueryInterval = New TimeSpan(0, 0, 5)
myApplication.SubscriptionQuantumLimit = 1
myApplication.ChronicleQuantumLimit = 1
myApplication.VacuumRetentionAge = New TimeSpan(0, 0, 1)
myApplication.LogBeforeDeliveryAttempts = False
myApplication.LogNotificationText = False
myApplication.LogStatusInfo = False
myApplication.EventThrottle = 500
myApplication.NotificationThrottle = 500
myApplication.SubscriptionThrottle = 500
myApplication.ProcessEventsInOrder = False
