WebHTMLViewer in Windows is too slow to load pdf

Hello again,
It seems that the problem is not the Windows filesystem but the WebHtmlViewer component.
The file is loading fast from the filesystem.
The command
myHTMLViewer.LoadURL(pdfWebFile.URL)
is very slow when I run the app on Windows.

So, after searching I used the recommendation here:

I copied the pdf files inside my web server root directory (The IIS root directory in Windows), and changed the code as bellow:

var myhtml As String
myhtml = " <embed src=““http://127.0.0.1/myfile.pdf”” style=““width: 100%;height: 100%;”” />"
myHTMLViewer.LoadHTML(myhtml)

Remember to change 127.0.0.1 with your server IP address, in order to be accessible from other clients.

Maybe this is helpful to others too.

P.S. I want to change the title of this topic from " Windows is to slow to load pdf" to “WebHtmlViewer in Windows is to slow to load pdf”. Can anybody tell how to do it?
