Performance Improvement

Thanks.

But you duplicate the wp_update_themes, and forget the wp_maybe_auto_update

	/**
	 * Filter cron events
	 *
	 * @since 		1.5.0
	 */
	public function filter_cron_events($event) {
		switch( $event->hook ) {
			case 'wp_version_check':
			case 'wp_update_plugins':
			case 'wp_update_themes':
			case 'wp_update_themes':
				$event = false;
				break;
		}
		return $event;
	}

This is not about removing, it’s about avoiding to schedule the future update check .

I’m analyzing all my wordpress queries ( 600+ per request in Admin ) and with my filter_cron_events

$ignore = array(
‘wp_version_check’,
‘wp_update_plugins’,
‘wp_update_themes’,
‘wp_maybe_auto_update’,
);

i reduce 8 update queries, 2 per hook. ( sometimes, the cron queries are very heavy )

Without my filter, wordpress is always removing the events from the cron ( + 4 queries ) and scheduling again ( + 4 queries ) for the next check in the future.

With my filter, i never schedule the next check ( -4 queries ), so if it’s not in the cron, we don’t need to remove them ( – 4 queries ).

Hope you understand.

By the way, i’m using wordpress 4.11 for now and can’t upgrade.
