jmh-benchmarks

What problem does it solve?

This Skill provides expert guidance for writing reliable Java microbenchmarks using the Java Microbenchmark Harness (JMH), ensuring accurate performance measurements and insightful analysis.

Core Features & Use Cases

• Benchmark Creation: Learn to set up and write basic JMH benchmarks.
• Performance Analysis: Understand different benchmark modes (Throughput, AverageTime, etc.) and state scopes.
• Optimization Pitfalls: Avoid common errors like dead code elimination, constant folding, and manual loops.
• Parameterization: Test performance across various configurations using @Param.
• Use Case: You need to compare the performance of two different sorting algorithms in Java. Use this Skill to create JMH benchmarks that accurately measure and compare their execution times under various conditions.

Quick Start

Use the jmh-benchmarks skill to generate a new JMH benchmark project using the Maven archetype.
