### Создание `Settings` только один раз с помощью `lru_cache` { #creating-the-settings-only-once-with-lru-cache }

Чтение файла с диска обычно затратная (медленная) операция, поэтому, вероятно, вы захотите сделать это один раз и затем переиспользовать один и тот же объект настроек, а не читать файл при каждом запросе.

### Die `Settings` nur einmal laden mittels `lru_cache` { #creating-the-settings-only-once-with-lru-cache }

### Creando el `Settings` solo una vez con `lru_cache` { #creating-the-settings-only-once-with-lru-cache }

Leer un archivo desde el disco es normalmente una operación costosa (lenta), por lo que probablemente quieras hacerlo solo una vez y luego reutilizar el mismo objeto de configuraciones, en lugar de leerlo para cada request.

### Creating the `Settings` only once with `lru_cache` { #creating-the-settings-only-once-with-lru-cache }

Reading a file from disk is normally a costly (slow) operation, so you probably want to do it only once and then reuse the same settings object, instead of reading it for each request.

But every time we do:
