🚀 Performance Profiler = Code Optimization

Slow code is frustrating. Performance Profiler finds bottlenecks. CPU, memory, async — optimize your app.

📝 Profiling Tools

# Open Diagnostic Tools
Debug → Open Diagnostic Tools (Alt+F2)

# Profiling Options
- CPU Usage
- Memory Usage
- Async Profiling
- .NET Object Allocation
- GPU Usage
- Database Query

# Start Profiling
Debug → Start Diagnostic Tools Without Debugging
OR
Alt+F2 → Select tool → Start

# Analyze Results
- Summary view
- Hot path detection
- Call tree
- Flame graph
- Function timing

# CPU Profiling
- Find CPU-intensive methods
- Identify bottlenecks
- Optimize hot paths

# Memory Profiling
- Memory leaks
- Large object allocations
- GC pressure
- Object retention

🎯 Profiling Workflow

# 1. CPU Profiling
Debug → Start Diagnostic Tools
Select CPU Usage
Run scenario
Stop profiling
Analyze hot path

# 2. Memory Profiling
Select Memory Usage
Take snapshot
Run scenario
Take snapshot
Compare snapshots

# 3. Async Profiling
Select Async profiling
Run async operations
Analyze async call tree

# 4. Database Profiling
Select Database query
Run data operations
Analyze SQL queries

# Optimization Tips
- Optimize hot methods
- Reduce allocations
- Improve data access
- Async for I/O
- Cache frequently used data

✅ Performance Tips

• Profile before optimizing
• Focus on hot paths
• Measure improvements
• Monitor memory usage
• Use async for I/O operations
