Property Value

A Int32 that specifies the maximum number of distributor threads.

Remarks

The default distributor thread pool size is 3.

The thread pool size determines the degree to which the distributor can perform work in parallel, and affects the overall performance of the Notification Services system.

The distributor thread pool size can be 1, 2, or 3 in Notification Services Standard Edition. The distributor thread pool value is unlimited in other editions. Note that the value represents a maximum; the actual number of threads depends on the availability of system resources.

For more information about how the distributor settings affect distributor operation, see Specifying Distributor Settings.

Example

The following examples show how to create a distributor, define the distributor's properties, and then add it to an application:

// Define distributor for application
Distributor distributor = 
    new Distributor(myApplication, "Distributor");
distributor.SystemName = notificationServicesHost;
distributor.QuantumDuration = new TimeSpan(0, 0, 15);
distributor.ThreadPoolSize = 2;
myApplication.Distributors.Add(distributor);

' Define distributor for application
Dim distributor As Distributor = New Distributor( _
    myApplication, "Distributor")
distributor.SystemName = notificationServicesHost
distributor.QuantumDuration = New TimeSpan(0, 0, 15)
distributor.ThreadPoolSize = 2
myApplication.Distributors.Add(distributor)
