When loading the blog posts from wp-admin the performance is crippled with this plugin activated.
Currently it is not suitable for high performance environments.
When performing this piece of code:
$sql = $wpdb->prepare(" LEFT JOIN" . $wpdb->postmeta . "
AS meta ON (" . $wpdb->posts . "
.ID = meta.post_id AND meta.meta_key = %s)", $_REQUEST['orderby']);
You need to add indexes.
Can you fix this please?
