Step 5

Click “Save Changes.” You can go back in there at any time if you need to change or disable the schedule.


Database optimization feature uses a background automation process to a cron job schedule at the end of it to confirm the cleanup has finished. You can use a real cron (or server-level cron); it just means that the UI message in the Perfmatters plugin settings might remains for a long time after running to confirm cleanup has finished. The timing would depend on what you have set for the database optimization schedule.

The cron will run based on the scheduled action you set, lets say daily, weekly, etc. Starting from the time you set it up for optimization. If you run a manual optimization, the schedule already set will remain the same.

Filter for HTTP Basic Auth (.htpasswd)

If you have HTTP Basic Auth (.htpasswd) protection on your WordPress admin, you will need to add the filter for the database optimization process to function properly.

We recommend it with the free Code Snippets plugin. Make sure to update the USERNAME and PASSWORD strings accordingly.

function wpbp_http_request_args( $r, $url ) {
 $r['headers']['Authorization'] = 'Basic ' . base64_encode( USERNAME . ':' . PASSWORD );
 return $r;
add_filter('http_request_args', 'wpbp_http_request_args', 10, 2);
