# Linux x86 so that we can use RBE. Since tests still need to run on the single

# For testing purposes, we want to see the runtime performance of an

# do not run them. By prefixing the configs with "build", we can run both

### JSON Performansı { #json-performance }

Kısaca, en yüksek performansı istiyorsanız bir [Response Model](../tutorial/response-model.md) kullanın ve *path operation decorator* içinde `response_class` tanımlamayın.

### etcd moves to version 3.5.0

Avec **FastAPI** vous obtenez toutes les fonctionnalités de **Starlette** (puisque FastAPI est juste Starlette sous stéroïdes) :

* Des performances vraiment impressionnantes. C'est [l’un des frameworks Python les plus rapides disponibles, à l’égal de **NodeJS** et **Go**](https://github.com/encode/starlette#performance).
* Prise en charge des **WebSocket**.
* Tâches d'arrière-plan dans le processus.
* Évènements de démarrage et d'arrêt.

```

/// tip | Dica

Em produção, você usaria `fastapi run` em vez de `fastapi dev`. 🚀

///

Internamente, o **FastAPI CLI** usa o [Uvicorn](https://www.uvicorn.dev), um servidor ASGI de alta performance e pronto para produção. 😎

O CLI `fastapi` tentará detectar automaticamente a aplicação FastAPI a ser executada, assumindo que seja um objeto chamado `app` em um arquivo `main.py` (ou algumas outras variantes).

それでも、どちらの状況でも、**FastAPI** はあなたが以前使っていたフレームワークよりも (少なくとも同等に) [高速である](index.md#performance) 可能性が高いです。

### 依存関係 { #dependencies }

[依存関係](tutorial/dependencies/index.md) についても同様です。依存関係が `async def` ではなく標準の `def` 関数である場合、外部のスレッドプールで実行されます。

### サブ依存関係 { #sub-dependencies }

C'est pourquoi **FastAPI** est basé sur Starlette, car il s'agit du framework le plus rapide disponible (testé par des benchmarks tiers).

mitigation to avoid disrupting load balancer → kube-apiserver connections if http/2 requests from multiple clients share the same backend connection. An API server on a private network may choose not to enable the kube-apiserver mitigation to prevent performance regressions for unauthenticated clients. Authenticated requests rely on the fix in golang.org/x/net v0.17.0 alone. https://issue.k8s.io/121197 tracks further mitigation of http/2 attacks by authenticated clients.
