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.
if ( current_user_can ( 'administrator' ) ) : ?>
echo get_num_queries ( ) ; ?> queries in timer_stop ( 1 ) ; ?> seconds .
endif ; ?>
