I Gzip my pages currently like so:

<?php
     ob_start("ob_gzhandler");

     //my page content

     ob_flush();
?>

However, I read a comment somewhere, earlier on, that this method uses a lot of memory, and I know that my website has been using a lot of memory on my virtual private server, so I thought it would be nice if I knew a way to reduce memory usage.

I tested my site with an online gzip tester which says my websites are sending gzipped pages, so my gzip method works, but the main obviously I'm looking for a less memory intensive option, if any.

I appreciate all suggestions. :) Oh and merry christmas ;P
