It’s easy to think that performance is someone else’s responsibility. However, when we think about apps at scale, it becomes clear that performance, like accessibility, is everyone’s responsibility. So how do we help change this mindset, especially for front-end developers? We do it by adopting a “shift-left” mindset, and take another look at how we both learn and teach web development. Blazing fast sounds nice as a sound byte and can even perhaps serves as a true north, but the journey to delivering that kind of business value is something that requires thinking at every level. In this talk, we’ll look what we mean by “shift left” and how we can take that journey— together.

About Aaron Turner
Observability for Web Perf
Within the observability community, there’s a saying, “nines don’t matter if users aren’t happy,” meaning that 99.999% server uptime is a pointless goal if our customers aren’t having a fast, smooth, productive experience. But how do we know if users *are* happy? As members of the web performance community, we’ve been thinking about the best ways to answer that question for years. Now the observability community is asking the same questions, but coming at them from the opposite side of the stack. What can we learn from each other?
Emily will talk about how approaching web performance through the lens of observability has changed the way her team thinks about performance instrumentation and optimization. She’ll cover the nuts & bolts of how Honeycomb instrumented its customer-facing web app, and she’ll show how the Honeycomb team is using this data to find and fix some of its trickiest performance issues, optimize customer productivity, and drive the design of new features.

The Secrets of High Performing Technology Organizations
How can we apply technology to drive business value? For years, we’ve been told that the performance of software delivery teams doesn’t matter―that it can’,t provide a competitive advantage to our companies. Through six years of groundbreaking research, the DORA team set out to find a way to measure software delivery performance―and what drives it―using rigorous statistical methods. This talk presents the findings of that research, including how to measure the performance of software teams, what capabilities organizations should invest in to drive higher performance, and how software leaders can apply these findings in their own organizations.

FMP, TTI, WTF? Making Sense of Web Performance
We all know that web performance is important; faster websites are beneficial for all users, no matter the country or the internet speed. But making websites more performant can be a daunting task. With a plethora of acronyms, it can be difficult to know where to start. This talk will cover how to make sense of the confusing world of web performance.
About Ire Aderinokun
Creating Performant Virtual Reality Experiences for the Web
WebXR brings a new approach and a suite of tools designed to take full advantage of the modern web to deliver virtual experiences in the browser. Under the hood, WebGL's hardware acceleration provides considerable performance gains. But as today's virtual reality applications continue to push the limits for what's possible on the web, we must find additional performance optimizations to create the most immersive experiences. In this session, we'll explore recent performance enhancements to WebXR that we can include in our applications today. We'll also take a look at common best practices to improve performance in virtual reality applications.

'Getting Out Of Users' Way: Less Jank With Web Workers
Does your web app make lots of data requests? Have you ever dealt with large datasets or slow data processing in your app? If so, you’re not alone.
These issues, and others like them, often lead to poor user experiences as our applications frequently show loading spinners, jank, or even freeze completely. These experiences are all too common on the web, but we have a solution: Web Workers.
About Trent Willis
Why we can’t have nice things
Performant web sites are critical for your user’s experience. No doubt about that. But keeping our users’ information private and secure is similarly critical to maintain their trust in the web platform and keep them around. Those two requirements are somewhat at odds.
There are many cases where performance optimizations ended up creating security or privacy holes. There are also many cases where privacy and security restrictions introduce significant performance overhead, or prevent us from getting access to performance-critical information in the wild.
In this talk, we’ll discuss different examples outlining this tension, dig deeper into them, understand the underlying principles behind the web’s security model, and hopefully agree that we need both a performant and safe web to keep our users happy.

One Number, Multiple Metrics: A Multidimensional Approach to Performance
Users experience the speed of your site at multiple points. Whether it’s loading the site, interacting with content, or completing a multi-page flow, performance is a journey and each step needs to be recorded. We have the tools to capture all of this information, but then what? How do you turn this treasure trove of data into a comprehensive and digestible story that answers the age-old question “is my site fast?” At Airbnb we’ve answered this question with a new approach to performance measurement, the Page Performance Score.
About Andrew Scheuermann
Andrew is a Senior Software Engineer at Airbnb, where he manages Airbnb’s web performance measurement initiatives and works on various product teams.
Turbocharging Walmart.com: Speed without compromise
eCommerce market is highly competitive and site speed plays a major role in improving overall buying experience and fulfilling user needs. In most companies there is always a constant push and pull towards spending time adding new features vs improving performance. There are also constraints around 3rd party integrations, ads & making changes happen across various teams can also be a challenge. In this talk we're going to look into ways by which you can smartly improve performance without cutting down on features and without changing much of the user's experience. We'll talk about different modern techniques that helped improve Walmart.com's cart & checkout experience and how understanding user behavior can go a long way in optimizing performance.

Betting on boring: Getting ahead with oldskool tech
It is an exciting time to be a web developer. New tools, technologies and opportunities are everywhere.
Sophisticated frameworks and libraries regularly promise "blazing fast" sites and incredible developer experience. How tempting! But wait a moment. Are we reinventing some things which already work beautifully? Are we solving problems which weren’t there until we created them?
Sometimes the best solution is the most boring one. This talk will explore the possibilities of embracing long established fundamentals of the web platform, and compare their application to that of advanced new technologies. We’ll compare the results in terms of developer and user experience, functionality, and performance from a variety of approaches. And show how betting on boring (perhaps, sometimes with a new twist), can deliver the most exciting and performant results.

The art of predictive prefetch
Browser hints like prefetch enable you to get critical resources in advance and save valuable (next) render time. These speculative optimizations integrate the developers assumptions about the users route. Speculative pre-fetching can be wasteful due to incidences of fetching resources that will never be used. Leaning on advances in machine learning and analytics data allows us to significantly increase the efficacy of our fetches. Let’s explore techniques that move predictive prefetching from idea to reality.
