# Django Performance Review Review Django code for **validated** performance issues. Research the codebase to confirm issues before reporting. Report only what you can prove. ## When to Use - You need a Django performance review focused on verified ORM and query issues. - The code likely has N+1 queries, unbounded querysets, missing indexes, or other database-driven bottlenecks. - You want only provable performance findings, not speculative optimization advice. ## Review Approach 1. **Research first** - Trace data flow, check for existing optimizations, verify data volume 2. **Validate before reporting** - Pattern matching is not validation 3. **Zero findings is acceptable** - Don't manufacture issues to appear thorough 4. **Severity must match impact** - If you catch yourself writing "minor" in a CRITICAL finding, it's not critical. Downgrade or skip it. ## Impact Categories Issues are organized by impact. Focus on CRITICAL and HIGH - these cause real problems at scale. | Priority | Category | Impact | |----------|----------|--------| | 1 | N+1 Queries | **CRITICAL** - Multiplies with data, causes timeouts | | 2 | Unbounded Querysets | **CRITICAL** - Memory exhaustion, OOM kills |
- When to Use
- Review Approach
- Impact Categories
- Priority 1: N+1 Queries (CRITICAL)
- Rule: Prefetch related data accessed in loops
- Rule: Prefetch in serializers, not just views
- Rule: Model properties that query are dangerous in loops
- Validation Checklist for N+1
- Priority 2: Unbounded Querysets (CRITICAL)
- Rule: Always paginate list endpoints
- Rule: Use iterator() for large batch processing
- Rule: Never call list() on unbounded querysets
- Validation Checklist for Unbounded Querysets
- Priority 3: Missing Indexes (HIGH)

Django performance code review. Use when asked to "review Django performance", "find N+1 queries", "optimize Django", "check queryset performance", "database performance", "Django ORM issues", or audit Django code for performance problems.
How do I install it?
Run `npx skills add sickn33/agentic-awesome-skills --skill django-perf-review --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From sickn33/agentic-awesome-skills, a repository with 44,414 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
