Comment (by Otto42):

 If you make that assumption that the $list array is full of similar
 objects or arrays, you do get a big speedup.

 {{{
 function new2_wp_list_pluck( $list, $field ) {
         if ( is_object( $list[0] ) ) {
                 foreach ( $list as $key => $value )
                         $list[ $key ] = $value->$field;
         } else {
                 foreach ( $list as $key => $value )
                         $list[ $key ] = $value[ $field ];
         }

         return $list;
 }

 float(1.2270720005035) : OLD
 float(0.61718487739563) : NEW
 float(0.35837507247925) : NEW2

 }}}
