It all started with Minecraft and my first Java mods. Today, I use those same tools to manage high-volume global traffic. I’m deeply fascinated by Java performance and its internal organs, which I enjoy dissecting right up until I hit C code. On a daily basis, I focus on high-performance system optimization and hunting down non-trivial production bottlenecks

Who's Slowing Down Your Application? Finding the Culprit When Logs and Metrics Fail
Conference - Short (INTERMEDIATE level)

When things in production aren’t running as fast as they should, and your logs and metrics are coming up empty, a real investigation begins. In this session, I’ll show you how the free, open-source Java Flight Recorder (JFR) can completely flip the script, dramatically accelerating the way you debug performance issues. Instead of hunting for the culprit blindly, JFR allows us to look "under the hood" of a running application and pinpoint the source of our problems with surgical precision.

I will share how we used JFR to solve real, non-obvious production mysteries, saving us a massive amount of time and stress in the process. My goal is for JFR to become a permanent resident in your production environments, providing you with invaluable insights into your application's behavior :)
