Long Loading Times IE 11

Hi,

I'm using Telerik UI for ASP.NET/AJAX and deployed my Website on IIS 7.5.7600.16385 on an Windows Server 2008 R2 Standard.

On the Server, .NET Framework 4.5.2 is installed.

In order to run the Website with IE 11 i had to add the following section to the webconfig-file:

<system.webServer>
<httpProtocol>
<customHeaders>
<add name="X-UA-Compatible" value="IE=Edge" />
</customHeaders>
</httpProtocol>
<modules>
<remove name="FormsAuthentication"/>
</modules>
</system.webServer>

Unfortunatedly, the loading times of the Website are very Long compared to when using Mozilla Firefox as Webbrowser (2-3 mins vs. 4-5 secs).

Any ideas hints on this?

Thanks,

Klaus
