Hi, Joe:

Below code in file Global.asax:

///////////////////////////////////////////////////////////////////////////////////////

protected void Application_EndRequest(Object sender, EventArgs e)
{

// update user activity at the end of each request
// but only if the siteUser is already in the HttpContext
// we don't want to lookup the user for little ajax requests
// unless we have to for security checks
if (HttpContext.Current.User == null)
return;

SiteUtils.TrackUserActivity(); // this line lead seriously performance problem.
}

///////////////////////////////////////////////////////////////////////////////////////

e.g:

When I goto http://localhost:61085/home.aspx, will lead below request

And every request will lead  Application_EndRequest(Object sender, EventArgs e) to be called,  and

lead SiteUtils.TrackUserActivity() to be called, and SiteUtils.TrackUserActivity()  will write my sqlitedb database,

for file database like sqltedb, it is a seriously performance problem.

A obvious result is my hard disk work too hard when i request a page.

Thanks!

Hi, Joe:

    I add <add key="TrackAuthenticatedRequests" value="false" /> in user.config or web.config, But it has no effect,  Application_EndRequest will be called too.

    Since this only happen in a production environment. I think it's not a problem then.

Thanks!

Hi, Joe

   I see.

   And I want ask whether in IIS .NET handle requests for *.css and *.js and *.axd?

   If handle these requests, then it's still a performance problem.

Thanks!
