Performance Profiling

Purpose

Systematically measure and analyze application performance using profiling tools to identify bottlenecks, hot paths, memory leaks, and inefficient operations.

When to Use

• Investigating slow operations or high latency
• Optimizing resource usage (CPU, memory, I/O)
• Diagnosing performance degradation
• Before and after performance improvements
• Capacity planning and scalability testing

Key Capabilities

1. CPU Profiling - Identify time-consuming functions and hot paths
2. Memory Profiling - Detect leaks, excessive allocation, and memory patterns
3. I/O Analysis - Find slow database queries, file operations, network calls
