About this skill

Java Profiling Workflow / Step 3 / Refactor code to fix issues

Implement refactoring based on profiling analysis: review profiling-problem-analysis-YYYYMMDD.md and profiling-solutions-YYYYMMDD.md, identify specific performance bottlenecks, and refactor code to fix them. Ensure all tests pass after changes.

What is covered in this Skill?

  • Review analysis notes: docs/profiling-problem-analysis-YYYYMMDD.md, docs/profiling-solutions-YYYYMMDD.md
  • Identify specific bottlenecks from the documented findings
  • Refactor code to address CPU hotspots, memory leaks, threading issues, or other performance problems
  • Run verification: ./mvnw clean verify or mvn clean verify

Scope: Changes must pass all tests. Apply fixes incrementally and verify after each significant change.

Constraints

Verify that changes pass all tests before considering the refactoring complete.

  • MANDATORY: Run ./mvnw clean verify or mvn clean verify after applying refactoring
  • SAFETY: If tests fail, fix issues before proceeding
  • BEFORE APPLYING: Read the analysis and solutions documents for specific recommendations
  • EDGE CASE: If request scope is ambiguous, stop and ask a clarifying question before applying changes
  • EDGE CASE: If required inputs, files, or tooling are missing, report what is missing and ask whether to proceed with setup guidance

When to use this skill

  • Refactor the code with profiling
  • Apply profiling
  • Refactor the code with profiling
  • Optimize hot path
  • Performance refactoring

Workflow

  1. Review profiling analysis artifacts

Read docs/profiling-problem-analysis-YYYYMMDD.md and docs/profiling-solutions-YYYYMMDD.md to select target bottlenecks.

  1. Apply targeted performance refactors

Implement focused code changes for documented CPU, memory, or threading hotspots, incrementally and safely.

  1. Verify behavior and performance build integrity

Run ./mvnw clean verify or mvn clean verify; if tests fail, fix issues before continuing.

  1. Prepare handoff for verification phase

Summarize implemented changes and expected metric improvements for Step 4 comparison.
