finding the end user load time

[ppk]

can we get the exact total load time of the webpage? I dont mind which
server is taking how much amount kind of stuff but what I am looking
for is:
time time the webpage took from the moment we click enter and the
complete page displayed.( by the way my test website is developed in
ajax)

SiteBlaster uses the WebBrowser control
(System.Windows.Forms.WebBrowser) to retrieve web pages and is reliant
upon the DocumentCompleted event to indicate when a page is finished
loading (http://msdn.microsoft.com/en-us/library/
system.windows.forms.webbrowser.documentcompleted.aspx ). The timing
statistics are based on the difference between the time the Navigate()
method (http://msdn.microsoft.com/en-us/library/40x214wa.aspx ) is
invoked and the DocumentCompleted event fires.

After a document has been loaded, it takes some time for the client
computer to display the page. This display time varies depending on
the size of the browser window. That is why you will get different
results when SiteBlaster is run in “full screen” and minimized modes.
I am not aware of any technique to get the display time.
