I have a website over at http://www.utopiapimp.com with over 15k users and it was getting bogged down a ton by database hits. I needed to speed the site up because of the DB calls. So I threw a ton of stuff into Cache, but that didn't speed the site up enough. So I looked for faster ways to do these things and wanted to give a shout out to this site that helped drastically.
Here is the link to the Article. I suggest you take a look at it if you wanted to do the same. http://www.codeproject.com/KB/aspnet/10ASPNetPerformance.aspx?msg=2809164
