The server side performance is not the focus of this series. It is often the first (or even only) part which many ASP.NET developers focus when on thinking about performance. When looking at page load times, it is often overrated as it is only one of many factors to consider. Nevertheless, should you take a look at your time to fist byte (i.e. execution time on the server + transport). Especially your HTML should be delivered as fast as possible as all dependent resources (images, css, js) are not loaded until the HTML has been parsed by the browser.
