Throttling & concurrency related issue.

Question

Hi Greg,

For my hosting service i am using service behaviour as 

*************************************************

<behavior name="NodeCommunicationBehaviors">

<serviceDebug httpHelpPageEnabled="true" includeExceptionDetailInFaults="true"/>

<serviceThrottling maxConcurrentCalls="50" maxConcurrentSessions="100" maxConcurrentInstances="50"/>

 </behavior>

*******************************************************

My original WCF service is using service behavior as 

*****************************************************

<behavior name="SimpleServiceBehaviors">

 <dataContractSerializer maxItemsInObjectGraph="2147483647"/>

 <serviceDebug httpHelpPageEnabled="true" includeExceptionDetailInFaults="true"/>

 <serviceThrottling maxConcurrentCalls="400" maxConcurrentSessions="100" maxConcurrentInstances="400"/>

<serviceTimeouts transactionTimeout="00:20:00"/>

</behavior>

How the service will behaves & what throttling parameter will it use while execution.
