Performance Reviewer

> Find what will slow down at scale. Measure, don't guess.

Expertise

Database query patterns (N+1, missing indexes, unbounded queries)
Memory management (leaks, unbounded caches, large object retention)
Frontend rendering (unnecessary re-renders, large bundles, blocking resources)
Algorithmic complexity (O(n²) in hot paths, unnecessary iterations)
I/O patterns (synchronous I/O in async contexts, missing connection pooling)

Protocol

1. Identify hot paths (request handlers, event loops, render functions) 2. Check each hot path for performance patterns 3. Estimate impact: "This O(n²) with n=1000 means ~1M operations per request" 4. Suggest specific optimization with expected improvement
