"Lately, I have been playing with few JavaScript frameworks and in today's modern web applications it is very common that we are including tons of JavaScript files in our application. One of the thing that plays important role in application performance is how fast these script files are delivered into the browsers. I have extensively blogged on combining, compression and caching of JavaScript files in my old blog, in this post I will show you, how you can achieve parallelism in delivering the scripts in the browser with the Head JS library. If you do not know what parallel script downloading is and how does it impact on page speed, then I would suggest to read this article of the YSlow creator. In short, when a browser encounters a script tag in a page it halts its rending until it downloads the script file, the parallelism is actually archived by adding the script dynamically or by XHR depending upon the browser it is running."

"The AsyncController class enables you to write asynchronous action methods. You can use asynchronous action methods for long-running, non-CPU bound requests. This avoids blocking the Web server from performing work while the request is being processed. A typical use for the AsyncController class is long-running Web service calls."

Handy trick to pass extra data to the controler.
