Server-Timing Header for Administrators
Adds a Server-Timing header with PHP time, database query count and peak memory to pages viewed by administrators, so you can read the numbers in your browser's developer tools Network tab.

Code
$wpide_server_timing = function () {
if ( headers_sent() || ! is_user_logged_in() || ! current_user_can( 'manage_options' ) ) {
return;
}
header( sprintf(
'Server-Timing: php;dur=%.1f;desc="PHP until the template starts", db;desc="%d queries", mem;desc="%s peak memory"',
timer_float() * 1000,
get_num_queries(),
size_format( memory_get_peak_usage( true ), 1 )
) );
};
// Sent just before the page template (or admin screen) starts rendering.
add_action( 'template_redirect', $wpide_server_timing, PHP_INT_MAX );
add_action( 'admin_init', $wpide_server_timing, PHP_INT_MAX );Notes
Visitors never receive the header; the time covers everything WordPress does before the page template starts rendering.
