Slow Admin

Thanks. We will evaluate the results.

Do the performance problems go away when you turn off AMP Developer Tools in your WordPress user profile settings?

No, not deactivate the AMP plugin as a whole. I’m talking about “AMP Developer Tools” in your WordPress user profile settings:

OK, I see you are right.

I have, however, found a way to prevent that slow query from happening. It shouldn’t actually be running when AMP Developer Tools are turned off, so that’s a bug we’ll fix. It doesn’t explain why the query is slow, but at least now I see why the query is running in the first place.

In any case, here is the plugin code that you can use to prevent that query from running:

add_action(
	'init',
	function () {
		$post_type_obj = get_post_type_object( 'amp_validated_url' );
		if ( ! $post_type_obj ) {
			return;
		}

		if ( $post_type_obj->show_in_menu ) {
			return;
		}

		remove_action( 'admin_menu', [ 'AMP_Validated_URL_Post_Type', 'add_admin_menu_new_invalid_url_count' ] );
	}
);

We’ll continue investigating why that query is slow in the first place.
