```Python hl_lines="1"
async def get_burgers(number: int):
    # burgerleri oluşturmak için asenkron birkaç iş
    return burgers
```

...`def` yerine:

```Python hl_lines="2"
# bu kod asenkron değil
def get_sequential_burgers(number: int):
    # burgerleri oluşturmak için senkron bırkaç iş

Imagine you are the computer / program 🤖 in that story.

While you are at the line, you are just idle 😴, waiting for your turn, not doing anything very "productive". But the line is fast because the cashier is only taking the orders (not preparing them), so that's fine.

```Python hl_lines="1"
async def get_burgers(number: int):
    # Fazer alguma coisa assíncrona para criar os hambúrgueres
    return burgers
```

...ao invés de `def`:

```Python hl_lines="2"
# Isso não é assíncrono
def get_sequential_burgers(number: int):

## `async` et `await`

`await` が機能するためには、非同期処理をサポートする関数内にある必要があります。これは、`async def` で関数を宣言するだけでよいです:

```Python hl_lines="1"
async def get_burgers(number: int):
    # ハンバーガーを作成するために非同期処理を実行
    return burgers
```

...`def` のかわりに:

```Python hl_lines="2"
# 非同期ではない
def get_sequential_burgers(number: int):
    # ハンバーガーを作成するためにシーケンシャルな処理を実行
    return burgers
```

Dennoch besteht in beiden Fällen eine gute Chance, dass **FastAPI** [immer noch schneller](index.md#performanz){.internal-link target=_blank} als Ihr bisheriges Framework (oder zumindest damit vergleichbar) ist.
