## 複本：行程與記憶體 { #replication-processes-and-memory }

在 FastAPI 應用中，使用像 `fastapi` 指令（執行 Uvicorn）的伺服器程式，即使只在「一個行程」中執行，也能同時服務多個客戶端。

但很多情況下，你會想同時執行多個工作行程（workers）。

### 多個行程 - Workers { #multiple-processes-workers }

如果你的客戶端比單一行程所能處理的更多（例如虛擬機規格不大），而伺服器 CPU 有「多核心」，那你可以同時執行「多個行程」載入相同的應用，並把所有請求分散給它們。

### Contenedores con Múltiples Procesos y Casos Especiales { #containers-with-multiple-processes-and-special-cases }

Por supuesto, hay **casos especiales** donde podrías querer tener **un contenedor** con varios **worker processes de Uvicorn** dentro.

En esos casos, puedes usar la opción de línea de comandos `--workers` para establecer el número de workers que deseas ejecutar:
