### 並行処理は並列処理より優れている？ { #is-concurrency-better-than-parallelism }

いいえ！それがこの話の教訓ではありません。

並行処理は並列処理とは異なります。そして多くの待ち時間を伴う**特定の**シナリオでは優れています。そのため、一般に Web アプリ開発では並列処理よりはるかに適しています。しかし、すべてに対して最良というわけではありません。

バランスを取るために、次の短い物語を想像してください。

 *  **Fix: improve parallelism of async requests.** OkHttp's Dispatcher had a
    misconfigured `ExecutorService` that limited the number of worker threads.
    If you're using `Call.enqueue()` this update should significantly improve
    request concurrency.

- API validation relaxed allowing Indexed Jobs to be scaled up/down by changing parallelism and completions in tandem, such that parallelism == completions.

    // For efficiency, especially in executors with limited
    // parallelism, check to see if previously submitted tasks are

### Eşzamanlılık ve Burgerler { #concurrency-and-burgers }

Yukarıda anlatılan **asenkron** kod fikrine bazen **"eşzamanlılık"** (concurrency) da denir. **"Paralellik"**ten (parallelism) farklıdır.

**Eşzamanlılık** ve **paralellik**, "aynı anda az çok birden fazla şeyin olması" ile ilgilidir.

Ama *eşzamanlılık* ve *paralellik* arasındaki ayrıntılar oldukça farklıdır.

Avec **FastAPI** vous pouvez bénéficier de la concurrence qui est très courante en développement web (c'est l'attrait principal de NodeJS).
