## Performance Tuning

### 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

#### Shared reader thread

    /**
     * Flag indicating whether crawler threads run as daemon threads.
     */
    protected boolean daemon = false;

    /**
     * Priority for crawler threads.
     */

    /**
     * Reference to the parent thread that started the crawler.
     */
    protected Thread parentThread;

    /**

   * intentionally, so there is no other way to clean up these threads. (The better solution,
