5 Things You’ll Finally Feel Confident Doing

Confidently diagnose memory leaks, GC issues, and thread bottlenecks
Interpret and act on GC logs, heap dumps, and thread dumps like a forensic expert
Tune garbage collectors (G1, ZGC, Shenandoah) for specific workloads.
Recognize early signs of performance degradation — and respond with precision.
Communicate performance root causes clearly across teams and stakeholders.

Differentiation from other Java Performance workshops

Not vendor-tool dependent: We focus on concepts over GUIs — useful with any toolchain.
Enterprise-grade realism: Real-world case studies instead of trivial examples.
Structure, not folklore: Diagnostic patterns and root cause frameworks — not just “tips and tricks.”
Two-day deep dive: From internals to applied tuning — this is not a surface-level course.
Interactive labs: You don’t just watch — you analyze, diagnose, and solve.

Bootcamp Day 1

Deep Dive into JVM Internals & Diagnostics:

We’ll dive deep into the inner workings of the Java Virtual Machine. This is not a high-level overview — you’ll dissect the core components of the JVM: threads, heap, metaspace, native memory, and HotSpot optimizations.

You’ll learn how to systematically analyze JVM artifacts such as garbage collection logs, thread dumps, and heap dumps — and how to draw actionable insights from them. Through hands-on labs with real-world examples, you’ll develop a structured, tool-independent approach to diagnosing JVM behavior.

Bootcamp Day 2

Troubleshooting Patterns & Performance Tuning at Scale:

Day 2 is all about applying advanced troubleshooting strategies and performance tuning techniques in real-world scenarios. You’ll learn timeless diagnostic patterns that can be used to solve production problems — whether it’s memory leaks, long GC pauses, or unexplained latency spikes.

We’ll explore how to tune modern garbage collectors like G1, ZGC, and Shenandoah, and how to adjust JVM parameters for specific workloads. Using real enterprise case studies, you’ll analyze complex performance issues and practice applying proven techniques to resolve them. By the end of the day, you’ll be equipped to not only understand but actively optimize and stabilize JVM-based applications at scale.
