Find memory growth patterns

Tools

instruments_analyzer.py - Parse Instruments traces

Commands

bash

# Analyze trace
./instruments_analyzer.py analyze app.trace

# Compare traces
./instruments_analyzer.py compare --baseline baseline.trace --current current.trace

# Find hot paths
./instruments_analyzer.py hotpaths app.trace --threshold 5%

# Memory analysis

Output

Performance Analysis
===================
Total Time: 2.45s
Top Methods:

1. drawRect: (456ms, 18.6%)
2. calculateStatistics (234ms, 9.5%)
3. readFromStore (198ms, 8.1%)

Recommendations:
- Cache drawRect results
- Optimize calculateStatistics algorithm
- Add index to database query
