# 基準測試

由第三方機構 TechEmpower 的基準測試表明在 Uvicorn 下運行的 **FastAPI** 應用程式是 <a href="https://www.techempower.com/benchmarks/#section=test&runid=7464e520-0dc2-473d-bd34-dbdfd7e85911&hw=ph&test=query&l=zijzen-7" class="external-link" target="_blank">最快的 Python 可用框架之一</a>，僅次於 Starlette 和 Uvicorn 本身（於 FastAPI 內部使用）。

但是在查看基準得分和對比時，請注意以下幾點。

## 基準測試和速度

當你查看基準測試時，時常會見到幾個不同類型的工具被同時進行測試。

具體來說，是將 Uvicorn、Starlette 和 FastAPI 同時進行比較（以及許多其他工具）。

В веб-сокете вызывать `HTTPException` не имеет смысла. Вместо этого нужно использовать `WebSocketException`.

As this is a WebSocket it doesn't really make sense to raise an `HTTPException`, instead we raise a `WebSocketException`.

You can use a closing code from the <a href="https://tools.ietf.org/html/rfc6455#section-7.4.1" class="external-link" target="_blank">valid codes defined in the specification</a>.

### Try the WebSockets with dependencies { #try-the-websockets-with-dependencies }

### Custom OpenAPI content type { #custom-openapi-content-type }

Using this same trick, you could use a Pydantic model to define the JSON Schema that is then included in the custom OpenAPI schema section for the *path operation*.

And you could do this even if the data type in the request is not JSON.

# ベンチマーク

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、<a href="https://www.techempower.com/benchmarks/#section=test&runid=7464e520-0dc2-473d-bd34-dbdfd7e85911&hw=ph&test=query&l=zijzen-7" class="external-link" target="_blank">利用可能な最速のPythonフレームワークの1つ</a>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

ベンチマークを確認する時、異なるツールを同等なものと比較するのが一般的です。
