Comment:

 I have implemented the change to reduce the redundant calls to
 `wp_setup_nav_menu_item()`, and in doing so eliminating a large number of
 postmeta lookups, in all resulting in about a ~200% speed boost. See
 [attachment:32769.diff​].

 The more in depth solution, lazy loading the settings and controls when
 the sections are expanded, will drastically reduce the load time yet
 again.
