XDocument.Load() takes ~14 seconds to read a simple xml file from Windows Server 2008 R2 IIS.

Hi,

I am using the below code to read an XML file from virtual directory (application hosted in IIS)

DateTime beforeStart = DateTime.Now;

var document = XDocument.Load("http://WindowsServer2008R2Machine/Site/ConfigurationFiles/Configuration.xml");

DateTime afterCompletion = DateTime.Now;

TimeSpan timeDiff = afterCompletion.Subtract(beforeStart);

MessageBox.Show("XDocument.Load took ~14 Milliseconds");

Trail 1:

Approach1: IIS present in Windows Server 2008 R2. XDocument.Load() code takes ~14 seconds.

Approach2: IIS present in Windows Server 2008 R2. Application.GetRemoteStream() code takes ~14 seconds.

Approach3: IIS present in Windows Server 2008 R2. XMLDocument.Load() code takes ~13 seconds.

All these approaches timings are so consistent for first time application launch but second time read onwards it takes less than 100 milli seconds.

Trail 2:

Approach1: IIS present in Windows Server 2008 R2. XDocument.Load() code takes > 100 ms.

Approach2: IIS present in Windows Server 2008 R2. Application.GetRemoteStream() code takes > 100 ms.

Approach3: IIS present in Windows Server 2008 R2. XMLDocument.Load() code takes > 100 ms.

No first time business here. Every time above 3 approaches takes > 100 milliseconds.

During My application start up, I need to read the XML file to get the configuration. Due to above reasons, whenever I connect to Windows Server 2008 R2, application start up takes long time.

Do I need to upgrade / update Windows Server 2008 R2 machine?

Could some one please help me solving this or any workaround? 

Thanks and Regards
