What are some best practices for improving the performance of including subpages in a PHP system?

When including subpages in a PHP system, it's important to optimize performance to ensure fast loading times. One best practice is to use PHP's output buffering functions to capture the output of the included subpage and then include it in the main page. This can help reduce the number of file system calls and improve overall performance. 

<?php
ob_start();
include 'subpage.php';
$subpage_content = ob_get_clean();

// Include the subpage content in the main page
echo $subpage_content;
?>
