Starlette（和 **FastAPI**）是基於 [AnyIO](https://anyio.readthedocs.io/en/stable/) 實作的，這使得它們與 Python 標準函式庫 [asyncio](https://docs.python.org/3/library/asyncio-task.html) 和 [Trio](https://trio.readthedocs.io/en/stable/) 相容。

特別是，你可以直接使用 [AnyIO](https://anyio.readthedocs.io/en/stable/) 來處理更複雜的並行使用案例，這些案例需要你在自己的程式碼中使用更高階的模式。

即使你不使用 **FastAPI**，你也可以使用 [AnyIO](https://anyio.readthedocs.io/en/stable/) 來撰寫自己的非同步應用程式，並獲得高相容性及一些好處（例如「結構化並行」）。

Starlette （和 **FastAPI**） 是基于 [AnyIO](https://anyio.readthedocs.io/en/stable/) 实现的，这使得它们可以兼容 Python 的标准库 [asyncio](https://docs.python.org/3/library/asyncio-task.html) 和 [Trio](https://trio.readthedocs.io/en/stable/)。

特别是，你可以直接使用 [AnyIO](https://anyio.readthedocs.io/en/stable/) 来处理高级的并发用例，这些用例需要在自己的代码中使用更高级的模式。

即使你没有使用 **FastAPI**，你也可以使用 [AnyIO](https://anyio.readthedocs.io/en/stable/) 编写自己的异步程序，使其拥有较高的兼容性并获得一些好处（例如， 结构化并发）。

Running `fastapi dev` initiates development mode.

By default, **auto-reload** is enabled, automatically reloading the server when you make changes to your code. This is resource-intensive and could be less stable than when it's disabled. You should only use it for development. It also listens on the IP address `127.0.0.1`, which is the IP for your machine to communicate with itself alone (`localhost`).

## `fastapi run` { #fastapi-run }

  runtime jitter. Watch the `Error` column in the benchmark results to see the run-to-run variance.
* Ensure to run enough warmup iterations to get the benchmark into a stable state. If you are unsure, don't change the defaults.
* Avoid CPU migrations by pinning your benchmarks to specific CPU cores. On Linux you can use `taskset`.
