Have you ever had the experience of trying to speed up your pages, then realizing that you're only responsible for 13 of the 187 HTTP requests? It's like getting ready to tune up your drag car, then walking around the back to see that the parachute can't be put back in.

Influencing a developer-centric company to care more about site performance is not a small task. We will walk through successful approaches to performance monitoring at Ancestry.com. These include collecting internal SLA statistics and implementing a grading system that focuses on the top 30 pages while correlating with business data.

CDNs fail regularly and in many different ways, varying from a small, local increase in latency to global unavailability. In this data-filled talk, we’ll present convincing evidence for why you need to prep for CDN failure, and practical guidance for monitoring CDN performance and implementing a multi-CDN strategy.

Responsive web design offers a solution to deliver the right web experience to every device. But its use can result in poor page load performance, which is made worse by bottlenecked wireless networks. Peter and Jesse will discuss some of the challenges around responsive web design, and solutions to dramatically improve page load times when using RWD.

Writing fast JavaScript code is not only microbenchmarks. Understanding the JavaScript engine will reveal the typical code patterns favored for maximum execution speed (short function, fixed object shape, profile-guided, garbage minimization). In addition, it is also important to consider other strategies such as sampling and tracing.
4:10pm–4:50pm Friday, 05/29/2015
Katie Kovalcin (Sparkbox)
Performance is a rising requirement for building successful websites, but successful performance begins far earlier than development. So how do you get your entire team excited by it, specifically aesthetic-heavy designers?

Zach Leatherman (Filament Group)

The default loading behavior for web fonts, making the text invisible until the font files have successfully loaded, is harmful to a performance-focused website. In this talk we’ll learn a variety of methods to progressively render web fonts and show a fallback while the fonts are loading. We’ll also show techniques to group repaint of web fonts from fallback text to improve usability.
2:40pm–3:20pm Thursday, 05/28/2015
Mark Zeman (SpeedCurve)

We increasingly rely on third-party scripts to deliver business-critical features of our sites, but do we understand the impact they're having on our site's performance and our business? In this session we’ll share the insights we’ve gained from analysing the impact third-party scripts have on the performance of our customers' sites, the value they deliver, and how our clients manage them.

The limitations of HTTP/1.X forced us to develop various application workarounds to optimize performance, but in the process we've also introduced numerous regressions: poor caching, unnecessary downloads, delayed execution, and more. Well, good news, because HTTP/2 eliminates this tradeoff: we can eliminate the hacks, simplify our applications, and deliver improved performance!
