+
+Les tests de performance Go sont disponibles dans `tests/performance/upload_endpoints_performance_test.go`.
+
+**Exécuter les tests de performance**:
+```bash
+cd veza-backend-api
+go test -tags=performance ./tests/performance -run TestPerformance -v
+```
+
+**Exécuter les benchmarks**:
+```bash
+cd veza-backend-api
+go test -tags=performance ./tests/performance -bench=Benchmark -benchmem
+```
+
+**Seuils de performance**:
+- Simple Upload: < 2s
+- Chunked Upload Initiate: < 100ms
+- Chunked Upload Chunk: < 200ms par chunk
+- Chunked Upload Complete: < 3s
+- Concurrent Uploads (10): < 10s total
+
 ## Notes
 
 - Les tests utilisent des **credentials invalides** pour `/api/v1/auth/login` (attendu: 401)
 - Les tests **ne modifient pas** de données (read-only sauf login qui échoue)
+- Les tests d'upload **nécessitent un token JWT valide** (AUTH_TOKEN)
+- Les tests d'upload **créent des fichiers de test** en mémoire
 - Ajuster les **seuils** selon votre infrastructure (ex: latence réseau, CPU, etc.)
