System.Web.HttpContext.Current.User.Identity.Name Vs System.Environment.UserName in ASP.NET

What is the difference between System.Web.HttpContext.Current.User.Identity.Name and System.Environment.UserName in the context of a ASP.Net Web Application Project?

Here's the code of what I'm trying to do: 

Database myDB = DatabaseFactory.CreateDatabase();
bool IsAuthUser = myDB.ExecuteScalar("procIsAuthorizedUser", System.Environment.UserName);

If they are functionally identical, which is better in terms of performance?

This is a C# 4.0/ASP.Net web application which will see moderate usage internally in the organization. Thank you for the answers.

System.Environment.UserName returns the identity under which the app pool that hosts your web app is running. If you're using Windows authentication and impersonation then it will be the actual user's name, however in all cases you're better off using the information provided by the HTTP context. There is no performance hit either way.
