# Benchmarks

Los benchmarks independientes de TechEmpower muestran aplicaciones de **FastAPI** que se ejecutan en Uvicorn como <a href="https://www.techempower.com/benchmarks/#section=test&runid=7464e520-0dc2-473d-bd34-dbdfd7e85911&hw=ph&test=query&l= zijzen-7" class="external-link" target="_blank">uno de los frameworks de Python más rápidos disponibles</a>, solo por debajo de Starlette y Uvicorn (utilizados internamente por FastAPI). (*)

# Test de performance

Les tests de performance de TechEmpower montrent que les applications **FastAPI** tournant sous Uvicorn comme <a href="https://www.techempower.com/benchmarks/#section=test&runid=7464e520-0dc2-473d-bd34-dbdfd7e85911&hw=ph&test=query&l=zijzen-7" class="external-link" target="_blank">étant l'un des frameworks Python les plus rapides disponibles</a>, seulement inférieur à Starlette et Uvicorn (tous deux utilisés au cœur de FastAPI). (*)

一般情况下可能不会需要在代码中直接使用响应头。

但对于某些高级应用场景，还是需要添加自定义响应头：

```Python hl_lines="14"
{!../../docs_src/handling_errors/tutorial002.py!}

```

## 安装自定义异常处理器

添加自定义处理器，要使用 [Starlette 的异常工具](https://www.starlette.io/exceptions/)。

假设要触发的自定义异常叫作 `UnicornException`。

且需要 FastAPI 实现全局处理该异常。

此时，可以用 `@app.exception_handler()` 添加自定义异常控制器：

```Python hl_lines="5-7  13-18  24"

	echo '{"version": "3", "credential": {"accessKey": "minio", "secretKey": "minio123"}, "region": "us-east-1"}' >"$MINIO_CONFIG_DIR/config.json"

	if [ ! -f /tmp/mc ]; then
		wget --quiet -O /tmp/mc https://dl.minio.io/client/mc/release/linux-amd64/mc &&
			chmod +x /tmp/mc
	fi
}

function perform_test() {
	start_minio_3_node $2

	echo "Testing Distributed Erasure setup healing of drives"

	}

	stsEndpointURL, err := url.Parse(stsEndpoint)
	if err != nil {
		log.Fatalf("Error parsing sts endpoint: %v", err)
	}

	opts := &minio.Options{
		Creds:  li,
		Secure: stsEndpointURL.Scheme == "https",
	}

	v, err := li.Get()
	if err != nil {
		log.Fatalf("Error retrieving STS credentials: %v", err)
	}

	if displayCreds {
		fmt.Println("Only displaying credentials:")

	if err != nil {
		return nil, err
	}

	creds := credentials.NewStaticV4(conf.AccessKey, conf.SecretKey, "")
	opts := &minio.Options{
		Creds:           creds,
		Secure:          u.Scheme == "https",
		Transport:       globalRemoteTargetTransport,
		TrailingHeaders: true,
	}
	client, err := minio.New(u.Host, opts)
	if err != nil {
		return nil, err
	}

Aus diesem Grund sind die aktuellen Versionen immer noch `0.x.x`, was darauf hindeutet, dass jede Version möglicherweise nicht abwärtskompatible Änderungen haben könnte. Dies folgt den Konventionen der <a href="https://semver.org/" class="external-link" target="_blank">semantischen Versionierung</a>.

# Benchmarks

Independent TechEmpower benchmarks show **FastAPI** applications running under Uvicorn as <a href="https://www.techempower.com/benchmarks/#section=test&runid=7464e520-0dc2-473d-bd34-dbdfd7e85911&hw=ph&test=query&l=zijzen-7" class="external-link" target="_blank">one of the fastest Python frameworks available</a>, only below Starlette and Uvicorn themselves (used internally by FastAPI).
