What are some best practices for optimizing the performance of a PHP guestbook with pagination functionality?

One best practice for optimizing the performance of a PHP guestbook with pagination functionality is to limit the number of records retrieved from the database for each page. This can help reduce the load on the server and improve the overall speed of the application. 

// Example code snippet for limiting the number of records retrieved for pagination
$page = isset($_GET['page']) ? $_GET['page'] : 1;
$records_per_page = 10;
$offset = ($page - 1) * $records_per_page;

$query = "SELECT * FROM guestbook_entries LIMIT $offset, $records_per_page";
// Execute the query and display the results
