Heres a little nifty snippet that will show the number of queries made and the page load time.
Add this code snippet to a template file during testing in the location where you want the info to show. In this example the output is wrapped in an “if user is administrator” condition – so that the output is only visible to users with administrator rights.
<?php if(current_user_can('administrator')): ?>
<?php echo get_num_queries(); ?> queries in <?php timer_stop(1); ?> seconds.
<?php endif; ?>
