Comment (by jrchamp):

 Hi @lubimow! The slow query you mentioned does not appear to be coming
 from WordPress core (the lowercase 'where' is very suspicious). It is
 likely coming from a plugin or your theme. For your site, you may want to
 consider adding an index to the guid column in the wp_posts table if the
 plugin/theme author is unable to provide fix.
