### Thread Configuration

```java
// Optimize thread pool settings
crawler.crawlerContext.setNumOfThread(20);           // Number of crawler threads
crawler.crawlerContext.setMaxThreadCheckCount(50);   // Thread monitoring frequency
```

### Connection Pool Tuning

```java
container.singleton("httpClient", HcHttpClient.class, client -> {
    client.setMaxConnections(200);          // Total connections

# セキュリティ入門

セキュリティ、認証、認可を扱うには多くの方法があります。

そして、通常、それは複雑で「難しい」トピックです。

多くのフレームワークやシステムでは、セキュリティと認証を処理するだけで、膨大な労力とコードが必要になります（多くの場合、書かれた全コードの50%以上を占めることがあります）。

**FastAPI** は、セキュリティの仕様をすべて勉強して学ぶことなく、標準的な方法で簡単に、迅速に**セキュリティ**を扱うためのツールをいくつか提供します。

しかし、その前に、いくつかの小さな概念を確認しましょう。

## OAuth2

OAuth2は、認証と認可を処理するためのいくつかの方法を定義した仕様です。
