How can session management in PHP impact the performance of scripts when loading resources?

Session management in PHP can impact the performance of scripts when loading resources if sessions are not properly handled. One common issue is that sessions can lock resources, causing other requests to wait until the session is released. To solve this, it's important to close the session as soon as it's no longer needed to free up resources for other requests.

// Start the session
session_start();

// Perform operations using session data

// Close the session to release resources
session_write_close();
