FIX: It takes a long time to add a new website in a shared hosting environment on a web server that is running IIS 7.0 or IIS 7.5

View products that this article applies to.

Symptoms

Consider the following scenario. In a shared hosting environment, you host many websites on a webserver that is running Internet Information Services (IIS) 7.0 or IIS 7.5. For example, you host one thousand websites on the webserver. Additionally, you create many application pools for these websites to run in. In this scenario, it takes several minutes to add a new website to the web server.

Cause

This issue occurs because the way that IIS maintains isolated configuration files causes performance issues in a shared hosting environment.

When a website in an application pool first receives a request from a client, the Windows Process Activation Service (WAS) creates an isolated configuration file. The WAS does this by filtering the configuration data for the application pool that is in the ApplicationHost.config file. By default, the isolated configuration file is located in the following directory:
%systemdrive%\inetpub\temp\appPools
In a shared hosting environment, many isolated configuration files are located in the same directory. When a new website is added to the web server, the ApplicationHost.config file is updated. This triggers an update of all the isolated configuration files. Because all the files are located in one directory, this process takes a long time.

Resolution

Note After you apply the hotfix, the isolated configuration files are located in different folders instead of being located in the same folder.
