   Hey all. I've written a totally useful and effective function that will sort through each of the sub-categories of a specified wordpress category, and list the most recent 10 articles within each sub-category. All is working well, but I fear my code may not be as efficient as it could be. I currently have a master category called "Articles" with four sub-categories, but this function scales as I add more sub-categories. The below function is adding 28 queries to my page...bringing me to a grand total of 69 queries.

   Any input would be terrific. Thanks!
   

   <?php
   //FUNCTION LOADS ALL SUBCATEGORIES FROM A SPECIFIED CATEGORY AND THEN
   //LISTS ARTICLES WITHING THAT CATEGORY IN AN ORDERED LIST
   
   $cat = 1; //manually specify category #1 which happens to be ARTICLES
   $displaynum = 10; //specify the # of articles headlines to show in each sub-category
   
   $args=array(
      'orderby' => 'name',
      'order' => 'ASC',
      'title_li' => '',
      'hide_empty' => '0',
      'parent' => $cat
   );
   $categories=get_categories($args);
   
   //LOOP THROUGH EACH SUBCATEGORY OF #1 ABOVE AND FORMAT IN DIV
   $countbox = 1;
   
   foreach($categories as $category) {
   echo '<div id="'.$category->slug.'" class="catbox ';
   //add right-padding to odd numbered boxes which appear on the left
   if( $odd != $countbox%2 ) echo 'leftbox'; else echo 'rightbox';
   echo '">';
   echo '<h3>'.$category->name.'</h3>';
   
       //OUTPUT HEADLINES FROM EACH SUBCATEGORY IN A LIST
   
       query_posts('category_name='.$category->slug.'&showposts='.$displaynum); {
       echo "\n<ul>";
       while (have_posts()) : the_post();
       echo '<li>';
       echo '<a href="';
       the_permalink();
       echo '">';
       the_title();
       echo '</a></li>';
       endwhile;
       echo "</ul>\n";
       }
   
   echo '
   <a class="more" href="' . get_category_link( $category->term_id ) . '"
   title="' . sprintf( __( "View all posts in %s" ), $category->name ) . '" ' . '>read more</a> ';
   echo '</div><!--end '.$category->slug.' div-->';
   echo "\n";
   $countbox++;
   
   }
   ?>
