## Revisa

Wie dem auch sei, in jedem der oben genannten Fälle wird FastAPI immer noch asynchron arbeiten und extrem schnell sein.

Wenn Sie jedoch den oben genannten Schritten folgen, können einige Performance-Optimierungen vorgenommen werden.

## What Does Activating a Virtual Environment Mean { #what-does-activating-a-virtual-environment-mean }

When you activate a virtual environment, for example with:

//// tab | Linux, macOS

<div class="termy">

```console
$ source .venv/bin/activate
```

</div>
