# Бенчмарки { #benchmarks }

Незалежні бенчмарки TechEmpower показують, що застосунки **FastAPI**, запущені під керуванням Uvicorn, є [одним із найшвидших доступних фреймворків Python](https://www.techempower.com/benchmarks/#section=test&runid=7464e520-0dc2-473d-bd34-dbdfd7e85911&hw=ph&test=query&l=zijzen-7), поступаючись лише самим Starlette і Uvicorn (використовуються FastAPI внутрішньо).

Але переглядаючи бенчмарки та порівняння, майте на увазі таке.

# Kıyaslamalar { #benchmarks }

Bağımsız TechEmpower kıyaslamaları, Uvicorn altında çalışan **FastAPI** uygulamalarının [mevcut en hızlı Python frameworklerinden biri](https://www.techempower.com/benchmarks/#section=test&runid=7464e520-0dc2-473d-bd34-dbdfd7e85911&hw=ph&test=query&l=zijzen-7) olduğunu, yalnızca Starlette ve Uvicorn'un kendilerinin altında yer aldığını gösteriyor (FastAPI bunları dahili olarak kullanır).

<div class="termy">

```console
$ python myapp.py
```

</div>

then the internal variable `__name__` in your file, created automatically by Python, will have as value the string `"__main__"`.

So, the section:

```Python
    uvicorn.run(app, host="0.0.0.0", port=8000)
```

will run.

This won't happen if you import that module (file).

So, if you have another file `importer.py` with:

sub-application could also have its own mounted sub-applications and everything would work correctly, because FastAPI handles all these `root_path`s automatically.

You will learn more about the `root_path` and how to use it explicitly in the section about [Behind a Proxy](behind-a-proxy.md)....
