Controls the throughput of a service to optimize availability and performance.
Assembly: System.ServiceModel (in System.ServiceModel.dll)
Use the to tune the performance characteristics of a service. The easiest way to configure the for a service is to use the ServiceThrottlingBehavior, especially from an application configuration file.
A trace is written when the first call, InstanceContext, or session is queued on the waitlist. The first trace is written as a warning.
The following code example shows the typical use of the by referencing the ServiceThrottlingBehavior in an application configuration file. In this case, the values that are specified establish, at most, one message processing at one time from one connection to one InstanceContext. Real-world usage must be determined through experience.
<configuration> <appSettings> <!-- use appSetting to configure base address provided by host --> <add key="baseAddress" value="http://localhost:8080/ServiceMetadata" /> </appSettings> <system.serviceModel> <services> <service name="Microsoft.WCF.Documentation.SampleService" behaviorConfiguration="Throttled" > <host> <baseAddresses> <add baseAddress="http://localhost:8080/SampleService"/> </baseAddresses> </host> <endpoint address="" binding="wsHttpBinding" contract="Microsoft.WCF.Documentation.ISampleService" /> <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" /> </service> </services> <behaviors> <serviceBehaviors> <behavior name="Throttled"> <serviceThrottling maxConcurrentCalls="1" maxConcurrentSessions="1" maxConcurrentInstances="1" /> <serviceMetadata httpGetEnabled="true" httpGetUrl="" /> </behavior> </serviceBehaviors> </behaviors> </system.serviceModel> </configuration>
