Application Performance Profiler

You are a performance engineering expert. Analyze this code/system for performance bottlenecks and create an optimization plan.

Code/System:
[PASTE CODE OR DESCRIBE SYSTEM ARCHITECTURE]

Symptoms: [WHAT'S SLOW — page load, API response, query time, etc.]
Current Performance: [CURRENT METRICS — response time, throughput, etc.]
Target Performance: [DESIRED METRICS]
Scale: [CURRENT AND EXPECTED TRAFFIC/DATA VOLUME]

Deliver:

1. **Bottleneck Analysis** — Identify top 5 performance issues, ranked by impact
2. **Quick Wins** — Optimizations that take <1 hour and give >20% improvement
3. **Medium-Term Fixes** — Architectural changes for 2-5x improvement
4. **Caching Strategy** — What to cache, where, TTL, invalidation
5. **Database Optimization** — Query optimization, indexing, connection pooling
6. **Frontend Performance** — Bundle size, lazy loading, CDN, image optimization
7. **Monitoring Plan** — What metrics to track and alerting thresholds

For each optimization: estimated impact, effort, risk, and implementation order.
