**Lightning Talks**

**Speeding up Heap Snapshots (From 10 minutes to 6 seconds!)**
*[Jason Williams](https://jason-williams.co.uk/), Bloomberg LP*
This lightning talk will explore some performance problems we discovered while diagnosing a memory leak in a JavaScript application, and how we fixed them to make JavaScript memory analysis faster than ever. We'll discuss the steps we took to achieve a 100x boost in speed to Heap Snapshot generation in collaboration with Igalia. The result: we reduced the time it took to capture a 100MB heap snapshot from a painful 10 minutes to a very pleasant 6 seconds!

**RUM & LoAF**
*[Erwin Hofman](https://www.erwinhofman.com/erwin-hofman/linkedin/), Independent + RUMvision*
As we (RUMvision) joined Chrome's LoAF OT, we recently started collecting data and believe LoAF will come with huge impact based on data so far.
Although still collecting, outcomes will be shared in this talk.

**Why We Need a "Green" Perf Metric**
*[Brian Louis Ramirez](https://screenspan.net/), Speed Kit by Baqend*
The Internet is the biggest machine ever built – and it has a huge impact on our environment. How can we as perf experts help make IT more sustainable? What would enable us to do more?

**Framework Tools for Image Optimization**
*[Kara Erickson](https://twitter.com/karaforthewin), Google*
The Chrome Aurora team has spent the last few years building performance-focused components and tooling into popular frameworks like Next.js, Angular, and Nuxt. Learn more about the image components we've built for these frameworks, how they improve performance, and how to include them in your next project.

**How to Build an Adaptive, Performant Web App**
*[Medhat Dawoud](https://www.medhat.dev/), Miro*
Learn to build adaptive web apps that respond to user behaviour and context. Discover responsive design principles, data-driven decision-making, and practical implementation. Improve user engagement with personalised web experiences through testing and feedback.

**CrUX to Sea Level: Lessons in Distilling RUM**
*[David Ross](https://hachyderm.io/@DRoss), Etsy*
How you tell & present a story from user data can encourage organizational buy-in (or hinder it). Go from aggregate data & rough SQL to the polished deck slide you're sending upward to management.

**Performant by Default**
*[Terry O'Shea](https://www.linkedin.com/in/terry-o-shea-455aba35/), Etsy*
Not every engineer can devote their career to improving web performance. How do we help the average product engineer—working on a deadline and juggling dozens of other requirements—make the right performance choices when building out a website? Drawing on case studies from the Etsy web performance team, let's talk about ways you can enforce perf best practices in your codebase as easily and automatically as possible.

**Networking Extravaganza**: Forge meaningful connections with peers, fellow performance aficionados, and potential collaborators throughout the event.

**Conference Speaker Appearance**: For those attending the conference speaker dinner on a boat, fret not! The boat will conveniently dock near the event venue, and a selection of our esteemed conference speakers will grace us with their presence. Seize this exceptional opportunity to mingle with industry luminaries.

Join us for an evening brimming with knowledge sharing, networking, and a celebration of performance excellence.

Save the date, spread the word, and we eagerly anticipate your presence at Kapitein Zeppos on **November 1st**!
