Display DB Queries, Time Spent and Memory Consumption

Snippets by IsItWP

Are you looking for a way to show statistics like DB queries in the footer of your website? While there’s probably a plugin for this, we have created a quick code snippet that you can use to display DB queries, time spent, and memory consumption in WordPress.


All you have to do is add this code to your theme’s functions.php file or in a site-specific plugin:

function performance( $visible = false ) {
    $stat = sprintf(  '%d queries in %.3f seconds, using %.2fMB memory',
        timer_stop( 0, 3 ),
        memory_get_peak_usage() / 1024 / 1024
    echo $visible ? $stat : "<!-- {$stat} -->" ;
add_action( 'wp_footer', 'performance', 20 );

Note: If this is your first time adding code snippets in WordPress, then please refer to our guide on how to properly copy / paste code snippets in WordPress, so you don’t accidentally break your site.
