因為這是 WebSocket，拋出 `HTTPException` 並沒有意義，因此我們改為拋出 `WebSocketException`。

你可以使用規範中定義的[有效關閉代碼](https://tools.ietf.org/html/rfc6455#section-7.4.1)之一。

# ベンチマーク { #benchmarks }

TechEmpowerの独立したベンチマークでは、Uvicornの下で動作する**FastAPI**アプリケーションは、[利用可能な最速のPythonフレームワークの1つ](https://www.techempower.com/benchmarks/#section=test&runid=7464e520-0dc2-473d-bd34-dbdfd7e85911&hw=ph&test=query&l=zijzen-7)であり、下回っているのはStarletteとUvicorn自体（FastAPIによって内部で使用される）のみだと示されています。

ただし、ベンチマークを確認し、比較する際には下記の内容に気を付けてください。

## ベンチマークと速度 { #benchmarks-and-speed }

ベンチマークを確認する時、異なるタイプの複数のツールが同等のものとして比較されているのを目にするのが一般的です。

how environment variables would be useful and applicable right away. But they keep showing up in many different scenarios when you are developing, so it's good to know about them.

For example, you will need this information in the next section, about [Virtual Environments](virtual-environments.md)....
