Comment(by rawalex):

 If you need the data and the count, why not just do the query and then a
 mysql_count_rows?  If you are just looking for the count, then severely
 limit the fields you are pulling in (wp_post.* is a bad choice if you
 don't need the data).  Less fields means less data space required.
