Back by popular demand, Harry will take you on a journey to help you become a Web Performance expert. Over the course of several sessions, he’s going to share some of his closest secrets, going from the back-end to the front, auditing the performance of real websites.

You’ll be plotting data and findings, making it compelling to clients and non-technical stakeholders; drawing up backlogs and hit-lists; hacking on fixes, improvements, and experiments; and learning a whole lot of forensic, detailed, and often completely obscure performance information on the way.


This Front-End Web Performance Workshop starts on the server and make it’s way to the user, looking at what parts of the journey can slow us down, and what we can do to mitigate this. CDN configurations, TLS performance, protocols, network utilisation, resource scheduling, critical path optimization, asset delivery and optimization, CSS performance, runtime and rendering, caching, and a whole lot more.

What Will This Workshop Cover?

The workshop begins with lessons on how to capture rich and insightful data, and subsequent lessons will be spent with the tooling needed to dissect and analyse it. The workshop ends with discussions around performance culture and monitoring, as well as ideas on how best to present findings and improvements back to the business.

Everything in between will be intensive, practical learning, as we tear down and rebuild your own sites with performance in mind! There is no script — we’re just gonna get busy. You’ll leave armed with a wealth of knowledge and tools, meaning you can do the whole lot again by yourself, anytime you want.

Who Is This Workshop For?

Attendees should have basic to intermediate familiarity with web performance concepts (e.g. minification, compression, image optimisation, etc.) but do not need in-depth knowledge of anything advanced. By the end of the workshop, you’ll all be experts.

What Hardware/software Do I Need To Bring?

  • A laptop with an up-to-date version of Chrome.
  • A live, public-facing website that you’re going to audit and fix.
  • Access to its Google Analytics account (optional but advised).
  • User accounts with several online tools. Harry will email you links to these ahead of time but rest assured, they’re all free and safe.
