Es war eines der ersten extrem schnellen Python-Frameworks, welches auf `asyncio` basierte. Es wurde so gestaltet, dass es Flask sehr ähnlich ist.

/// note | Technische Details

Es verwendete <a href="https://github.com/MagicStack/uvloop" class="external-link" target="_blank">`uvloop`</a> anstelle der standardmäßigen Python-`asyncio`-Schleife. Das hat es so schnell gemacht.

В любом из случаев выше FastAPI всё равно работает асинхронно и очень быстро.

Но следуя этим шагам, он сможет выполнить некоторые оптимизации производительности.

## Технические подробности { #technical-details }

Современные версии Python поддерживают **«асинхронный код»** с помощью **«сопрограмм»** (coroutines) и синтаксиса **`async` и `await`**.

Разберём эту фразу по частям в разделах ниже:

* **Асинхронный код**

Debido a eso, ahora se recomienda en su lugar usar el `lifespan` como se explicó arriba.
