What problem does it solve?

This Skill addresses performance bottlenecks in Java applications by providing guidance on JVM tuning, garbage collection, and profiling techniques.

Core Features & Use Cases

  • Garbage Collection Tuning: Select and configure appropriate GC algorithms (Serial, Parallel, G1, ZGC, Shenandoah) based on application needs and heap size.
  • Memory Management: Optimize heap, young generation, and metaspace settings.
  • Profiling & Analysis: Utilize tools like JFR, JMC, and async-profiler to diagnose issues and identify memory leaks or CPU hotspots.
  • Use Case: A high-traffic e-commerce application experiences frequent latency spikes during peak hours. This Skill can help diagnose if GC pauses are the cause and guide the selection of a low-latency collector like ZGC, along with appropriate tuning parameters.

Quick Start

Use the JVM Performance Optimization skill to analyze GC logs and suggest tuning parameters for a G1 GC collector.
