Modern Performance in the Year of the Dog
It’s 2018 and with the explosion of people joining the internet for the first time, building a performant application is more crucial than ever before. Unfortunately with all the new tools, libraries, and measurements, it’s difficult to even know where to start when it comes to building an application from scratch. In this talk, we’re going to cover the steps and methodologies that the modern web developer should keep in mind when crafting code. From choosing the right libraries and understanding application architecture, all the way to debugging common performance issues, we’re going to learn how to build a modern, production ready web application.

Workshop: Get Up to Speed
Websites may be slow, but the web itself moves fast. Every day new techniques and tools emerge, promising to make your site faster and lighter. New articles are written about the latest "best practices" in performance, only to have yet newer articles contradict them. When the technologies and techniques we use to make websites more performant change so quickly, it’s easy to feel like you’re falling behind.
But if you pull back the layers and the hype, drilling into the core concepts of how the network and browsers we rely on actually work, it suddenly becomes much easier to recognize which best practices are actually appropriate for you, and what trade-offs you’re making.
In this workshop, we’ll go beyond the latest and greatest techniques and tools to understand what is going on at the core. We’ll explore:
· How the browser renders pages, from the very first request on the network to the final pixel on your screen
· What the critical rendering path is and how to optimize for it
· How HTTP/2 differs from HTTP/1 and what that means for popular opimizations
· How to identify common performance bottlenecks in your sites and applications
By the time we’re done, you’ll have a firm understanding of what makes sites fast, and how to separate the hype from reality.

Perceived Performance: The only kind that really matters
Web performance has made incredible strides in the last few years, which has presented developers with a new problem: How do we efficiently improve our app’s performance now that we’ve plucked the low hanging fruit from the vine? How do we make an API driven app faster when the performance bottleneck are API requests? The answer is directly manipulating users' perceptions in order to make our projects *feel* faster than they really are.
This isn’t easy. Humans are imprecise beings, and how we perceive the world around us is fraught with fascinating quirks. Improving perceived performance is likewise an incredibly challenging prospect. If people don’t perceive time accurately, how can you possibly hope to build to meet this nebulous standard?
In this talk, Eli will discuss the psychological basics of how people sense time, and how to use this understanding to create experiences that feel fast, tactile, and create the illusion of speed. He’ll break down real world, actionable guidelines on:
- When it makes sense to focus on perceived performance over outright speed
- How to turn the difference between active and passive mental states to our advantage
- How to make "fake" progress bars feel genuine
- How to cleverly craft animations to make loading seem faster
- When to use unconventional event listeners to increase perceived speed
- Predictive preloading: The art of anticipating user behavior and loading assets just in time

Raiders of the Fast Start: Frontend Performance Archaeology
There are a lot of books, articles, and online tutorials out there with fantastic advice on how to make your websites performant. It all seems easy in theory, but applying best practices to real-world code is anything but straightforward. Diagnosing and fixing frontend performance issues on a large legacy codebase is like being an archaeologist excavating the remains of a lost civilization. You don’t know what you will find until you start digging!
Pick up your trowels and come along with Etsy’s Frontend Systems team as we become archaeologists digging into frontend performance on our large, legacy mobile codebase. I’ll share real-life lessons you can use to guide your own excavations into legacy code:
- What tools and metrics we used to diagnose issues and track progress.
- How we went beyond server-driven best practices to focus on the client.
- Which fixes successfully increased conversion, and which didn’t.
Our work, like all good archaeology, went beyond artifacts and unearthed new insights into our culture. We at Etsy pride ourselves on our culture of performance, but, like all cultures, it needs to adapt and reinvent itself to account for changes to the landscape. Based on what we’ve learned, we are making the case for a new, organization-wide, frontend-focused performance culture that will solve the problems we face today.

Making the browser faster
There are lots of talks about how web developers can make their sites run faster. In this talk, let’s turn the tables and look at how browser developers can make their browsers faster.
We’ll see how a CSS engine can be modified to run up to 18x faster, and how you can get up to 400 frames per second by rendering like a 3D game engine. Then we’ll talk about other future directions to explore in speeding up the browser.

Third-party content: the weak link in the chain
Third-party content is the thorn in the side of many a good website. From A/B testing that delays render to advertising networks that bleed user data, we depend on services over which we have no control. In an ideal world we could attribute a user experience cost to each third-party provider, allowing marketing, eCommerce and business intelligence to make educated decisions about which providers should stay and which should go.
The Resource Timing API allows site owners to measure how third-parties perform for every single pageview. Combining this data with business intelligence provides new insight to the impact of third-party providers on business performance.
This talk explores some of the toughest questions in web performance, backed up with huge amounts of data:
- Will moving to a new advertising network increase ad revenue?
- Is A/B testing losing more revenue that it gains?
- Does measuring web performance impact web performance?
Data for this talk has been gathered from over 500,000 websites, with detailed investigation performed on millions of pageviews from a small number of sites.
You will leave this talk armed with the tools and knowledge to measure the performance of third-party providers and provide compelling arguments for whether they should stay or go.

The Past, Present and Future of Resource Loading: Why the web is slow and what can we do about it
Loading resources on the Web has always been a performance hurdle. Suboptimal protocols and late discovery caused it to be the common performance bottleneck. In recent years advances in network protocols and performance APIs improved resource loading significantly, but there's still room to make it even faster.
In this talk, Yoav Weiss will go over resource loading improvements browsers have made in recent years, discuss related best practices and describe various innovations that are being worked on to improve resource loading even further.

The Power of Storytelling
If you want people to pay attention, learn, or remember something important, tell them a story. Stories help us connect with others and are easy for our brain to remember. Stories are all around us in tech from the user stories we create when developing features to the marketing messages crafted. But did you know stories are also hidden inside of metrics?
Organizations today are measuring hundreds or even thousands of metrics to measure performance including front-end, back-end, and business metrics. What story are these metrics telling us? In this session learn how to identify who your audience is and craft a story using metrics that will resonate with them. Understand which metrics matter and should be the star of your story and who the supporting characters are.

Progressive Web Apps: Show Up for Offline First, but Stay for the Killer Performance Boost
There is a big push for Offline First development, with a new buzzword — "Progressive Web App", or PWA — making the rounds for the last year or two. But a lot of what’s being said sounds like the coding equivalent of "eat your vegetables!".
What is in it for ME? Quite a bit, it turns out.
In this talk, Jason Lengstorf will share the surprising ways that online apps will see huge benefits when they’re built to support offline users. Learn how to add blazing speed gains to existing sites with just a few simple changes — and how you can easily add Offline First support to your apps with just a few lines of code.
Learn how going Offline First will improve the connected experience, including:
- better performance
- increased stability and reliability
- improved user experience
- and more!
So in addition to eating your vegetables — you know, making your web apps usable for people with slow and unreliable connections and whatnot — you will ALSO see your apps perform even better for connected users. All with minimal effort required.
