////

这里唯一的新选项是 `--workers` 告诉 Uvicorn 启动 4 个工作进程。

您还可以看到它显示了每个进程的 **PID**，父进程（这是**进程管理器**）的 PID 为`27365`，每个工作进程的 PID 为：`27368`、`27369`， `27370`和`27367`。

## 部署概念

在这里，您学习了如何使用多个**工作进程（workers）**来让应用程序的执行**并行化**，充分利用 CPU 的**多核性能**，并能够处理**更多的请求**。

从上面的部署概念列表来看，使用worker主要有助于**复制**部分，并对**重新启动**有一点帮助，但您仍然需要照顾其他部分：

| `minio_node_io_read_bytes`                 | Total bytes read by the process from the underlying storage system, /proc/[pid]/io read_bytes.                  |
| `minio_node_io_wchar_bytes`                | Total bytes written by the process to the underlying storage system including page cache, /proc/[pid]/io wchar. |
