Yes, comments can slow your website down. Big or small, comments have something to say when it comes to page size. Use caching
Set the browser?s cache expiration. This can be easily done using PHP in order to send some headers. For example, let's take a js file called scripts.js. In order to use caching we will create a new file called scripts.js.php and add the following code at the very beginning of it which will set the cache to expire in 3 days:
<?php
header("Content-type: text/javascript; charset: UTF-8");
header("Cache-Control: must-revalidate");
$offset = 60 * 60 * 24 * 3;
$ExpStr = "Expires: " .
gmdate("D, d M Y H:i:s",
time() + $offset) . " GMT";
header($ExpStr);
?>
By using this method you will not speed the first (initial) download but it will have some impact on the overall experience when you're browsing multiple pages or for returning visitors since the content will be already cached.
