Do you ever asked yourself how long it took for your page to load, or how many sql queries were executed? If yes, here is a simple code to insert on your template.

Nothing hard here. Simply paste the following code on your footer.php file:

<?php echo get_num_queries(); ?> queries in <?php timer_stop(1); ?>  seconds.

The get_num_queries() function returns the number of executed query during your page loading.
