Raiders of the Fast Start: Frontend Performance Archeology 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.

Web 3.0 extends Web 2.0 with technologies like machine-to-machine communication, IPv6, artificial intelligence, 5G networks, fiber internet connections at home, and a peer-to-peer internet. It is predicted that every home will have computing power equivalent to Google today and people will have personalized web experiences. Google may go bankrupt as people gain this power and the company needs to explore new business models. Technologies like smart pencils, real-time handwriting recognition, and plagiarism detection could enable new forms of education and learning tracking.

Metrics are everywhere! We’ve done a great job of keeping pace with measuring the output of our applications, but how are we doing with measuring what really matters? This talk will explore the various metrics available to application owners today, highlight what’s coming tomorrow and level-set on the relative importance as it relates to the user experience.

This document summarizes key points about optimizing performance for mobile web: 1. Mobile platforms are dominated by iOS and Android, with different browsers on each (Safari, Chrome). Understanding the ecosystem is important for testing and optimization. 2. Perception of speed is critical - aim for responses within 1 second. Mobile hardware is less powerful so optimization is needed. Tools like emulators, remote inspectors, and APIs help measure performance. 3. For initial loading, focus on getting above-the-fold content within 1 second using techniques like avoiding redirects, gzipping files, separating critical CSS, and deferring non-essential assets.

The document discusses the state of jQuery and the jQuery Foundation. It provides an overview of the non-profit jQuery Foundation organization and its projects.

It's no denying that rich Javascript applications (sometimes called One Page Applications) are a big thing, but what if you want to leverage Drupal on the backend, or have an existing site? Tools like Angular.JS and EmberJS are great when you have an API, but Drupal 7 doesn't really have an API layer. I'll explore the parts of a one page application and how to integrate it into either an existing or a new Drupal site, and the pitfalls that one must watch out for. Sample code for the demos are available at https://github.com/dragonmantank/spa-drupal
