NTLM Authentication for websites is a great addition to the bat-belt when writing ASP.Net sites. Additionally it is also a great to have support for it in Team Foundation & SharePoint portals. However as great as having support for NTLM authentication may be, having to enter & re-enter your credentials when surfing Intranet or Extranet sites can be an annoyance that is just not worth it.

ASP.Net web applications are awesome most of the time. But there is a sad reality: ASP.Net applications are tuned to handle huge amounts of traffic, not 50 page views a day. This becomes an issue when you have limited traffic to your site, because if your it doesn’t keep being viewed, your application pool may recycle, and that important visitor number 1 gets screwed waiting as your site rebuilds or your app pool to fires up. Whether it’s a SharePoint site, an ASP.Net or your internal TFS 2008/TFS 2010 Server, you want it to be FAST… all the time.
