Performance Lessons from the World’s Largest Angular Application

What do you do when your application is simply "too slow"?

This session is a (not-so-fictional) journey inside a team's performance investigation. We'll show you why jumping straight into the code is the wrong move and how to start with data-driven monitoring to define what "slow" actually means.

Join us as we follow the clues, hunt down one bottleneck after another, and navigate the difficult, real-world trade-offs between speed, features, and user experience.
This isn't just a talk about performance tips; it's a story about the process. You'll leave with a practical mindset for diagnosing users' issues and building usable, high-performance Angular applications.
