How do I improve ASP.NET MVC application performance?

Code Climber and this blog entry provide detailed ways of increasing application's performance.

Compiled query will increase performance of your application, but it has nothing in common with ASP.NET MVC. It will speed up every db application, so it is not really about MVC.

One super easy thing to do is to think asynchronously when accessing the data you want for the page. Whether reading from a web service, file, data base or something else, use the async model as much as possible. While it won't necessarily help any one page be faster it will help your server perform better overall.
