Recommended configuration values for congestion control in ADFS 2.0 in Windows

Applies to: Windows Server 2008 R2 DatacenterWindows Server 2008 R2 EnterpriseWindows Server 2008 R2 for Itanium-Based Systems


After you install update 2607496 , you can configure the congestion control. The default congestion control value may not match your environment.


We recommend that you set the latencyThresholdInMSec element to 8000 and the minCongestionWindowSize element to 64. To do this, update or add the following elements under the <microsoft.identityServer.proxy> section in the Microsoft.IdentityServer.Servicehost.exe.config file:
<congestionControl latencyThresholdInMSec="8000" minCongestionWindowSize="64" /> 
For more information about how to configure the elements for congestion control, refer to the Congestion Avoidance Algorithm section in the following KB article:
