Jeremy Wagner is a performance-obsessed front end developer, author and speaker living and working in the frozen wastes of Saint Paul, Minnesota. He is also the author of the Manning Publications book Web Performance in Action, a web developer’s companion guide for creating fast websites. You can find him on Twitter @malchata, or read his blog of ramblings.
The landscape for the performance-minded developer has changed significantly in the last year or so, with the emergence of HTTP/2 being perhaps the most significant of all. No longer is HTTP/2 a feature we pine for. It has arrived, and with it comes server push!
Chances are pretty good that you’ve worked with, or at least understand the concept of, server compression. By compressing website assets on the server prior to transferring them to the browser, we’ve been able to achieve substantial performance gains.
