しかし、多くの場合、複数のワーカー・プロセスを同時に実行したいと考えるでしょう。

### 複数のプロセス - Worker { #multiple-processes-workers }

クライアントの数が単一のプロセスで処理できる数を超えており（たとえば仮想マシンがそれほど大きくない場合）、かつサーバーの CPU に**複数のコア**がある場合、同じアプリケーションで同時に**複数のプロセス**を実行させ、すべてのリクエストを分散させることができます。

同じAPIプログラムの**複数のプロセス**を実行する場合、それらは一般的に**Worker／ワーカー**と呼ばれます。

### ワーカー・プロセス と ポート { #worker-processes-and-ports }

Bu yüzden bu örnekte `response_model` parametresinde declare etmek zorundayız.

...ama bunu nasıl aşabileceğinizi görmek için aşağıyı okumaya devam edin.

Toutes les mêmes options sont prises en charge.

Tous les mêmes `parameters`, `responses`, `dependencies`, `tags`, etc.
