Performance Profiler Tools

Analyze Instruments trace files and performance data.

Capabilities

• Parse Instruments .trace files
• Extract Time Profiler data
• Analyze Allocations data
• Generate performance reports
• Compare trace files
• Identify performance regressions
• Calculate time percentages
• Find memory growth patterns

Tools

instruments_analyzer.py - Parse Instruments traces

Commands

Copy# 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
./instruments_analyzer.py memory app.trace

===================
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
