We all know that your website’s performance is critical to the success of its mission. Conversion rates are proven to plummet if with every second of page load time. 

What can we do about this? Why is the web still slow in 2018?

In this session, we’re going deep into modern web performance, and you will learn how to identify and fix performance bottlenecks in your website / webapp through topics such as:

  • Web performance metrics you should be measuring and how. Which are the most important?
  • How do I optimize my site for each of these web performance metrics
  • How browsers render web pages, and how to use this knowledge to optimize the loading experience.
  • What is the critical path? How do I account for this?
  • What is the JavaScript main thread? How can I optimize for this?
  • Identifying, profiling, and optimizing for third party scripts.

In order to get the most out of this session, the attendee will have to 1) have some knowledge of HTML, CSS, and JavaScript, 2) have a basic understanding of browser-based developer tools, and 3) find slow websites extremely annoying.
