## 9. Performance Considerations

### 9.1 Memory Management
- Lease entries should be evicted based on LRU when max leases reached
- Implement periodic cleanup of expired leases

### 9.2 Thread Safety
- Use concurrent data structures for lease storage
- Minimize lock contention in hot paths
- Async handling of lease breaks

### 9.3 Network Efficiency

# Utiliser des dépendances avec `yield` { #dependencies-with-yield }

FastAPI prend en charge des dépendances qui effectuent des <dfn title='parfois aussi appelées « exit code », « cleanup code », « teardown code », « closing code », « context manager exit code », etc.'>étapes supplémentaires après l'exécution</dfn>.

Pour cela, utilisez `yield` au lieu de `return`, et écrivez les étapes supplémentaires (code) après.

/// tip | Astuce

	// Object operations.

	// GetObjectNInfo returns a GetObjectReader that satisfies the
	// ReadCloser interface. The Close method runs any cleanup
	// functions, so it must always be called after reading till EOF
	//
	// IMPORTANTLY, when implementations return err != nil, this
	// function MUST NOT return a non-nil ReadCloser.

# Dependencies with yield { #dependencies-with-yield }

FastAPI supports dependencies that do some <dfn title='sometimes also called "exit code", "cleanup code", "teardown code", "closing code", "context manager exit code", etc.'>extra steps after finishing</dfn>.

To do this, use `yield` instead of `return`, and write the extra steps (code) after.

/// tip

Make sure to use `yield` one single time per dependency.
