majiayu000 Performance Review Skill
When to Use
- Code performance optimization
- Memory leak fixes
- Throughput improvements
- Performance review requests
- Bottleneck analysis
Performance Analysis Workflow
Profiling → Identify bottlenecks → Optimize → Verify
Checklist
Algorithm & Data Structures
- Time complexity analysis (Big-O)
- Appropriate data structure selection
- Remove unnecessary operations
Memory
- Minimize memory allocation
- Object reuse (pooling)
- Cache-friendly access patterns
Concurrency
- Minimize lock contention
- Leverage async I/O
- Thread pool optimization
Caching
- Appropriate cache strategy
- Cache invalidation policy
- Cache hit rate monitoring

Caution
"Premature optimization is the root of all evil" - Donald Knuth
Always confirm bottlenecks through profiling before optimizing.
