Two file sizes are used -- regular (1.6mb, 1000 objects) and large (128mb, 100000 objects)

input size | lib | MB/s | Allocated
--- | --- | --- | ---
regular | standard | 97 | 3.6MB
regular | jstream | 175 | 2.1MB
large | standard | 92 | 305MB
large | jstream | 404 | 69MB

In a real world scenario, including initialization and reader overhead from varying blob sizes, performance can be expected as below:

By using them, you can take advantage of all these standard-based tools, including these interactive documentation systems.

OpenAPI defines the following security schemes:

* `apiKey`: an application specific key that can come from:
    * A query parameter.
    * A header.
    * A cookie.
* `http`: standard HTTP authentication systems, including:

# Response – Statuscode ändern

Sie haben wahrscheinlich schon vorher gelesen, dass Sie einen Standard-[Response-Statuscode](../tutorial/response-status-code.md){.internal-link target=_blank} festlegen können.

In manchen Fällen müssen Sie jedoch einen anderen als den Standard-Statuscode zurückgeben.

## Anwendungsfall

Stellen Sie sich zum Beispiel vor, Sie möchten standardmäßig den HTTP-Statuscode „OK“ `200` zurückgeben.

`standard` を加えることで、Uvicornがインストールされ、いくつかの推奨される依存関係を利用するようになります。

これには、`asyncio` の高性能な完全互換品である `uvloop` が含まれ、並行処理のパフォーマンスが大幅に向上します。

### Import typing's `List`

In Python 3.9 and above you can use the standard `list` to declare these type annotations as we'll see below. 💡

But in Python versions before 3.9 (3.6 and above), you first need to import `List` from standard Python's `typing` module:

```Python hl_lines="1"
{!> ../../docs_src/body_nested_models/tutorial002.py!}
```
