Creating a Performance InspectorĮach worker process of each web application on each front-end web server has its own performance inspector that is initialized with information from the web application’s HttpThrottleSettings property. The two major steps to the initialization are described in the following subsections. If the web application is reset, the system is reinitialized with the first request following the reset. Subsequent requests to the same process reuse the entities and threads that are initialized in that first request. The throttle control system is initialized during the BeginRequest event of the first HTTP request to a specific worker process on a specific front-end web server.
