Comment (by nacin):

 Care to tell us how long the query in is_multi_author() is taking? How
 many rows in your posts table?

 This function is not new. It was used similarly in Twenty Eleven and
 Twenty Twelve as well.

 I was thinking about an optimization the other day to is_multi_author(),
 but it would only help for multi-author blogs. Basically:
 {{{
 $is_multi_author = ( count( array_unique( wp_list_pluck( 'post_author',
 $wp_query->posts ) ) ) > 1 );
 }}}

 If that returns false, we'd have to do the query either way. That said, I
 find it hard to believe that query is taking a particularly long time.
