15459	Need Better Page Hierarchy Display Algo	truthmedia		"WordPress 3.0.1

File: /wp-admin/includes/post.php

Lines: 904-912

Code:
{{{
	// Hierarchical types require special args.
	if ( is_post_type_hierarchical( $post_type ) ) {
		$query['orderby'] = 'menu_order title';
		$query['order'] = 'asc';
		$query['posts_per_page'] = -1;
		$query['posts_per_archive_page'] = -1;
	}

	wp( $query );
}}}

The code in the area mentioned above causes our site to use over 170mb of memory on each load of the Pages index.  This really should be improved to accommodate sites that have large amounts of hierarchical data.  Looks to me like it's pulling all the data for all the pages on the site.  Perhaps a solution where unnecessary data is not included might be better here (such as content or excerpt)."	enhancement	new	normal	Future Release	Performance	3.0.1	normal		needs-patch	warkior batmoo@…
