Update decreases the page load time of web sites that are hosted on Windows 7-based and Windows Server 2008 R2-based web servers

Applies to: Windows 7 EnterpriseWindows 7 ProfessionalWindows 7 Ultimate More

Introduction


This update lets Internet Information Services (IIS) on Windows 7-based and Windows Server 2008 R2-based web servers use the Application Initialization feature. This feature decreases the page load time of the initial requests to an application on the web server.

More Information


When an application is not initialized, the page load times are very long for the initial requests. Web applications are recycled periodically, especially on high-traffic sites. Therefore, when a user requests the application during a slow-response time, the page load time can be up to 30 seconds, or possibly longer.

The Application Initialization feature of IIS is used to resolve this issue. However, the feature does not work correctly on Windows 7 and Windows Server 2008 R2 because the pipeline API does not pass the necessary data. This feature can fix most performance issues of the web sites that are hosted on a Windows-based web server.
