Performance Profiler

Measure, profile, and optimize application performance. Covers CPU profiling, memory analysis, flame graphs, benchmarking, load testing, and language-specific optimization patterns.

When to Use

• Diagnosing why an application or function is slow
• Measuring CPU and memory usage
• Generating flame graphs to visualize hot paths
• Benchmarking functions or endpoints
• Load testing APIs before deployment
• Finding and fixing memory leaks
• Optimizing database query performance
• Comparing performance before and after changes
