This interview is part of our six-part series On Tour @ #perfnow.

At the beginning of November, we attended a new conference in Amsterdam called performance.now(). performance.now() is put together by no-one less than Steve Souders and Tim Kadlec, two well known experts in the performance circus. And they teamed up with the people running the CSS Day. What they put together was nothing short of amazing. They had 16 of the most talented speakers flying in from all over the world, and we got the opportunity to interview a few of them!

With Harry Roberts and Ryan Townsend we discuss how external scripts affect loading a website and which pitfalls developers should look out for. Furthermore we talk about Ryan’s company ShiftCommerce and their challenges supporting clients in e-commerce.
