# Performance Profiler

Identify performance bottlenecks and optimization opportunities.

## Analysis Types

- CPU profiling
- Memory analysis
- I/O bottlenecks
- Algorithm complexity

## Metrics Tracked

- Execution time
- Memory usage
- Function call counts
- Database queries

## Example Report

```
PERFORMANCE REPORT

⏱️ Total execution time: 2.3s
💾 Peak memory: 128MB
🔄 Function calls: 45,234

HOT SPOTS:

1. processData() - 1.2s (52%)
   Line 45: Nested loop O(n²)
   Suggestion: Use Map for O(1) lookup

2. fetchUsers() - 0.8s (35%)
   N+1 query pattern detected
   Suggestion: Use batch query

3. renderList() - 0.2s (9%)
   Re-renders on every update
   Suggestion: Add memoization

OPTIMIZATION POTENTIAL:
Estimated improvement: 60-70% faster
