# Java Profiling Workflow / Step 4 / Verify results Verify performance optimizations through rigorous before/after comparison: ensure baseline and post-refactoring profiling data use identical test conditions, generate post-refactoring reports, compare metrics (memory, CPU, GC, threading), perform side-by-side flamegraph analysis, document findings in profiling-comparison-analysis-YYYYMMDD.md and profiling-final-results-YYYYMMDD.md, and validate success criteria. **What is covered in this Skill?** - Pre-refactoring baseline: run profiler with same load before changes - Post-refactoring: generate new reports with identical test conditions - Comparison: memory (leaks, allocations, GC), CPU (hotspots, contention), visual flamegraph comparison - Documentation: profiler/docs/profiling-comparison-analysis-YYYYMMDD.md, profiler/docs/profiling-final-results-YYYYMMDD.md - File naming: baseline/after suffixes, timestamp-based organization - Validation: verify reports exist, compare metrics, identify regressions **Scope:** Identical test conditions are critical. Document test scenarios. Validate application runs with refactored code before generating new reports. ## Constraints Use identical test conditions between baseline and post-refactoring. Verify both report sets are complete. Document test scenarios. - **CONSISTENCY**: Use identical test conditions and load patterns for baseline and post-refactoring - **VALIDATE**: Ensure both baseline and post-refactoring reports exist an...
