title: How to make wordpress get_field() faster
body: <p>I have 80 post entries which have a custom field with number value. When I get them with query_posts( $args ), and then in foreach get that property "get_field('date_last_check')" it take insane 15 seconds.</p>
  
  <p>If I try to solve it with meta_query</p>
  
  <pre><code>            array(
                  'key'=&gt;'date_last_check',
                  'compare' =&gt; '&lt;',
                  'value' =&gt; time() - (24 * 60 * 60)
              )
  </code></pre>
  
  <p>It also takes 12 seconds to complete that query. </p>
  
  <p>Is there anything i can do to solve this slowness ?</p>
