Performance Optimization

Find and fix bottlenecks.

Measurement First

• Profile before optimizing
• Establish baseline metrics
• Identify top bottlenecks

Common Issues

N+1 Queries

• Use JOINs or batch queries
• Check ORM lazy loading

Memory Leaks

• Check unclosed resources
• Review event listener cleanup

Blocking Operations

• Async for I/O
• Worker threads for CPU

Large Payloads

• Pagination
• Compression
• Lazy loading

Checklist

• Database queries indexed
• No unbounded loops
• Caching for hot paths
• Assets optimized
• Bundle size checked

Anti-Patterns

• Premature optimization
• Optimize without measuring
• Trade correctness for speed
