Imagine you're building an ASP.NET MVC website which has some performance problems. I'm sure this would never actually happen to you, but imagine you're facing this problem just for the sake of exploring the possibilities. :-)
Now, your web app is mostly fast and responsive, but there are certain types of data that just bring the whole thing to a grind. This article will cover a technique using ASP.NET MVC partial views, along with just a sprinkle of jQuery, JavaScript, and HTML5 to make your site feel nice and responsive even if you cannot increase the speed of certain operations.
