User Experience and Performance Here's the above the fold count of each MPM, categorized as low impact, medium impact, and high impact: Count Module Score 10 Low impact 10 2 Medium impact 4 2 High impact 12 14 Total 26 By checking the file sizes of each MPM, you can assess each MPM's impact. As mentioned before, this is mainly intended to bring design and developers together to quickly sketch out performance impacts of the different content modules. It lets you easily determine elements that might be too heavy to present above the fold.

This might not be the most scientific translation of perceived performance, but it's useful for getting everybody on the same page during the early wireframing and design stages of a project: Module Points Description Low impact 1 Small images, mostly static content and simple graphics, interaction elements like buttons and text fields. Medium impact 2 Medium-sized images and simple scripts. High impact 6 Large images and third-party scripts loading either heavy JavaScript or User Experience and Performance Module Points Description both JavaScript and images (such as adverts).

The lower the number, the better the expected performance. This approach suggests that you don't have to starve your website by following performance patterns.

It only means that the website has been created with the concept of applying and following web performance paradigms, which I'll explore in more detail in later chapters. Measurable Performance Modules A measurable performance module (MPM) describes a simplified and single performance unit in a wireframe.
