how environment variables would be useful and applicable right away. But they keep showing up in many different scenarios when you are developing, so it's good to know about them.

For example, you will need this information in the next section, about [Virtual Environments](virtual-environments.md)....

     *
     * <p>This calculation is only a heuristic based on our conventions.
     * In detail, the algo relies on the following assumptions: <ul>
     * <li>The parent uses aggregation and refers to the child via the modules section</li>
     * <li>The module path to the child is considered to
     * point at the POM rather than its base directory if the path ends with ".xml" (ignoring case)</li>

And as you can have parallelism and asynchronicity at the same time, you get higher performance than most of the tested NodeJS frameworks and on par with Go, which is a compiled language closer to C <a href="https://www.techempower.com/benchmarks/#section=data-r17&hw=ph&test=query&l=zijmkf-1" class="external-link" target="_blank">(all thanks to Starlette)</a>.

### Is concurrency better than parallelism?

Nope! That's not the moral of the story.

Sie können einen „Closing“-Code verwenden, aus den <a href="https://tools.ietf.org/html/rfc6455#section-7.4.1" class="external-link" target="_blank">gültigen Codes, die in der Spezifikation definiert sind</a>.

### WebSockets mit Abhängigkeiten ausprobieren

**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). (*)

To understand more about it, see the section <a href="https://fastapi.tiangolo.com/benchmarks/" class="internal-link" target="_blank">Benchmarks</a>....

Поля `example` как такового не существует в стандартах **JSON Schema**. В последних версиях JSON-схемы определено поле <a href="https://json-schema.org/draft/2019-09/json-schema-validation.html#rfc.section.9.5" class="external-link" target="_blank">`examples`</a>, но OpenAPI 3.0.3 основан на более старой версии JSON-схемы, которая не имела поля `examples`.

# 基準測試

由第三方機構 TechEmpower 的基準測試表明在 Uvicorn 下運行的 **FastAPI** 應用程式是 <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">最快的 Python 可用框架之一</a>，僅次於 Starlette 和 Uvicorn 本身（於 FastAPI 內部使用）。

但是在查看基準得分和對比時，請注意以下幾點。

## 基準測試和速度

當你查看基準測試時，時常會見到幾個不同類型的工具被同時進行測試。

具體來說，是將 Uvicorn、Starlette 和 FastAPI 同時進行比較（以及許多其他工具）。

# 基准测试

第三方机构 TechEmpower 的基准测试表明在 Uvicorn 下运行的 **FastAPI** 应用程序是 <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">可用的最快的 Python 框架之一</a>，仅次于 Starlette 和 Uvicorn 本身 (由 FastAPI 内部使用）。(*)

但是在查看基准得分和对比时，请注意以下几点。

## 基准测试和速度

当你查看基准测试时，几个不同类型的工具被等效地做比较是很常见的情况。

具体来说，是将 Uvicorn，Starlette 和 FastAPI 一起比较（在许多其它工具中）。
