Peformance problems on multisite since upgrade

I’m having performance problems since upgrading my multisite network to 3.8. Mostly in a custom theme I’ve been working on for this site: howlingwolfmedia.com/site. Everything was working well b4 upgrade. Now pages take forever to load. Network console in firefox shows hanging in different places. Header files use these tags:

<script src="<?php bloginfo ('template_url');?>/jquery-ui/js/jquery-1.9.1.js"></script>
<script src="<?php bloginfo ('template_url');?>/jquery-ui/js/jquery-ui-1.10.3.custom.js"></script>
<script src="<?php bloginfo ('template_url');?>/jquery-ui/js/ux.js"></script>
<link rel="stylesheet" type="text/css" media="screen" href="<?php bloginfo ('template_url');?>/jquery-ui/css/ui-lightness/jquery-ui-1.10.3.custom.css" />
<link href="<?php bloginfo('stylesheet_url'); ?>" rel="stylesheet" type="text/css"/>
