Au final, peu importe le cas parmi ceux ci-dessus, **FastAPI** fonctionnera de manière asynchrone et sera extrêmement rapide.

Mais si vous suivez bien les instructions ci-dessus, alors **FastAPI** pourra effectuer quelques optimisations et ainsi améliorer les performances.

## Détails techniques

Les versions modernes de Python supportent le **code asynchrone** grâce aux **"coroutines"** avec les syntaxes **`async` et `await`**.

De todos modos, en cualquiera de los casos anteriores, FastAPI seguirá funcionando de forma asíncrona y será extremadamente rápido.

Pero al seguir los pasos anteriores, podrá hacer algunas optimizaciones de rendimiento.

## Detalles Técnicos

Las versiones modernas de Python tienen soporte para **"código asíncrono"** utilizando algo llamado **"coroutines"**, con la sintaxis **`async` y `await`**.
