Performance optimization analysis: CPU/memory profiling, caching strategies, database query optimization, connection pooling, concurrency patterns, memory leak detection, and throughput improvement. Use when code is slow, memory usage is high, latency needs reduction, or conducting performance reviews before release.

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.
