Django Performance Review
Review Django code for validated performance issues. Research the codebase to confirm issues before reporting. Report only what you can prove.
Review Approach
- Research first - Trace data flow, check for existing optimizations, verify data volume
- Validate before reporting - Pattern matching is not validation
- Zero findings is acceptable - Don't manufacture issues to appear thorough
- 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 |
