Admin-ajax.php slow..Why is it even there?

I am not sure if views is the issue, but I am trying to get rid of admin-ajax.php from loading on every page. It is slowing down my site and it seems to be a few plugins that are loading code into every page whether its used or not. The code below looks to be called from this plugin, but had nothing to do with 99% of the pages on my site. Is there a way to remove it and lessen the calls to the page?

<script type="text/javascript">
            var front_ajaxurl = '/wp-admin/admin-ajax.php';
            var wpv_calendar_image = 'http://d7j863fr5jhrr.cloudfront.net/wp-content/plugins/wp-views/embedded/res/img/calendar.gif';
            var wpv_calendar_text = 'Select date';
        </script>
