This metabase property specifies how often the thread gating mechanism in IIS checks the CPU load.
Important
IIS performs thread gating to dynamically
control the number of concurrently executing threads, in response
to varying load conditions. The default settings for this property,
and the other thread gating properties, are designed to be
appropriate for the majority of server configurations and traffic
conditions. Changing these properties can lead to significant
performance degradation.The Web service setting for this property is applicable to all in-process and pooled out-of-process application nodes, at all levels. Metabase settings at the Web server level or lower will be ignored for in-process and pooled out-of-process applications. However, settings at the Web server level or lower will be used if that node is an isolated out-of-process application.
