The Latest on Measuring Web Performance

Patrick Meenan, Engineering Fellow Catchpoint

Patrick is going to explore the current state of web performance measurement, both in a lab (synthetic) environment and from real users (RUM). There has been a lot of exciting advancement in this space with Google's Core Web Vitals and evolving of other metrics over the years.

We will also explore how synthetic and RUM data complement each other and when each is most appropriate to use.

Overview of the Core Web Vitals metrics

Annie Sullivan, Staff Software Engineer Google

The Core Web Vitals provide unified guidance that is essential to delivering a great user experience. Annie will talk about why and how these metrics were developed, how you can measure them on your site, and how they fit into the bigger picture of a product's user experience.

Building a Performance Culture

Claire Tran, Software Engineering Manager, Director SafetyCulture, Women Who Code Sydney

A great user experience often ties into the performance of an application. The user’s first impression of the site they are visiting can be a make or break scenario, and if the performance is slow that can have an impact on the growth of a business. Behind the scenes, there are teams working on an application, performance is sometimes an afterthought and becomes a focus later on. In this talk, I will cover what performance culture looks like, how this starts and some ways to communicate the value of performance, as well as ways to drive engagement.

How Russian Doll Caching Can Improve Server Side Rendering

Abdurrachman Mappuji, Lead Software Engineer Mekari

Are you implementing SSR for your web application? Do you know we can implement multiple layers of caching so that your caching is like an onion 🧅 or Russian Doll🪆?

That's the essence of this talk, we'll demonstrate how we can implement Russian Doll Caching to create layers of caching so that we get data from databases as small as we possibly can.

Hopefully, after this talk, you'll not ask about Russian Mall what? Russian %^&*() caching?

Native Lazy Loading

Anton Ball, Front End Developer Doist

A conference called Lazy Loading must feature a talk on lazy loading! With native lazy loading introduced in Chrome 77 and other browsers following suite, now is a fantastic time to refresh on what's available today.

We are going to look at how and where native lazy loading can be used, potential gotchas and how it can help improve your site performance both with images and JavaScript alike. You'll come away from this talk with more knowledge on lazy loading even though the property appears deceptively simple at first glance.

How to read a WebPageTest waterfall chart

Matt Hobbs, Head of Frontend UK Government Digital Service

WebPageTest is one of the most well known and important tools in the web performance community. It's been actively developed by Pat Meenan since he worked at AOL in 2008. It has become the go to tool for both very simple to very advanced debugging of the web performance of a website. One of its most well known charts is the waterfall chart.

In this talk I'm going to introduce the waterfall chart and also go into detail on how you can examine and read it. The more you understand about the chart, the the more WebPageTest as a whole will be able to help you fix a slow performing website.

May 28

Is your Progressive Web App Lazy? How to read and improve your PWA Performance

Laura Morinigo, Developer Advocate/Principal Engineeer Samsung Internet

A progressive web app is a way to bring a native app experience into the browser, therefore the idea is to have a progressive enhancement of your app but during our development process, we have to keep in mind a few factors in order to make it. During this talk, we are going to discuss possible how to read and test our PWA performance and which are the tools that can help us to deliver web apps that are fast and progressive (for real!).

Optimizing the performance of third-party dependencies

Performance Upgrades with WebAssembly and the Edge

Aaron Turner, Senior Software Engineer Fastly

This talk will be taking a look at how WebAssembly and Edge Computing can improve your front end performance of your Application. We will take a look at what WebAssembly is, how it can be used to replace hot paths in your JavaScript Application. What Edge Computing is, and how it can be used to provide additional performance to low end devices. Lastly, we will look at how they can be used together for portable and performant applications.

On the Cutting Edge: a Glimpse into the Future of Web Performance

Rita Kozlov, Product Manager, Workers Cloudflare

Cloudflare Workers enables deploying a serverless application instantly, from a developer's computer to the edge - as close as possible (tens of milliseconds!) to every internet user around the world.

This is made possible by running V8 isolates - the same engines powering Chrome, on Cloudflare's global CDN network, spanning 194+ data centers around the world. For end users this means blazing fast, always available applications due to the reduced latency of requests traveling around the globe, and no cold starts, due to the lightweight nature of isolates, as compared to containers. For developers this means more time spent writing code, and building features, rather than scaling and optimizing cloud configurations.

This talk will cover the landscape of what platforms offer at the edge today, and how edge-based serverless is changing the web stack: from incremental dynamism at the edge, to the evolution of JAMstack on the edge and beyond!

About Us

Co-founded and now run by John Allsopp, Web Directions has for over 15 years brought together leading developers, engineers, visual, IxD, UX and product designers, Art and Creative Directors, product managers indeed everyone involved in producing web and digital products to learn from one another, and the World's leading experts across this vast field.

We spend our lives thinking about what comes next, keeping up with trends in technology, practices and processes, and filtering the hype, to make sure you don't miss trends that matter, and don't waste time on hype that doesn't.

We promise attending one of our events will leave you significantly better versed in the challenges you face day to day, and in solutions for addressing them.

Due to the COVID-19 pandemic, we're switching things up a bit for 2020 and beyond. We'll be organising a growing family of focussed online conferences, and our annual extravaganza, Web Directions Summit will take place in Sydney as soon as it is practicable in 2021 (all going well).
