Abstract

Starting with a demo web site that is not optimized, i will demonstrate step by step how the user experience can be improved. Improving the speed the end user experiences in his browser is more than writing efficient code. The goal is to reduce the time between the initial request and the moment the browser actually shows something. I will show how to improve javascript and css loading and how to use the caching proxy Varnish. With Edge Side Includes (ESI) it can even cache partly personalized pages.
