Yukarıdaki durumların herhangi birinde FastAPI yine de asenkron olarak çalışır ve son derece hızlıdır.

Ancak yukarıdaki adımları izleyerek bazı performans optimizasyonları mümkün olur.

## Teknik Detaylar { #technical-details }

```console
// "Code" adında bir dizin oluştur
$ mkdir code
// O dizine geç
$ cd code
```

...ve bir Python code örneği...

```Python
wont_work()  # Bu çalışmayacak 😱
works(foo="bar")  # Bu çalışır 🎉
```

...ve hepsi bu.

**FastAPI** her şeyin doğru sırada çalışmasını sağlar.

Bu, Python'un [Context Managers](https://docs.python.org/3/library/contextlib.html) yapısı sayesinde çalışır.

**FastAPI** bunu sağlamak için içeride onları kullanır.
