# Review Perf

> General application performance review for non-Django code (Flask, FastAPI, Go, Node, generic Python). Use when asked to "review performance", "audit performance", "find slow code", "perf review", or audit app-tier code for blocking I/O on async paths, algorithmic blow-ups, per-item network loops, unbounded memory accumulation, or missing application caching. Find-only — use optimize-perf to apply fixes with benchmarks. Covers the application surface that review-django-perf (Django ORM) and sql-reviewer (raw SQL / migrations) do not. Validation-first — no flag without traced evidence.
