Multiple loops in wordpress with minimal database queries

Hello everyone.

I’m using WordPress as a CMS and what I’m trying to do is create a site-map type footer that’s going to list all pages within each category. An example of this would be what’s going on in the footer of this website – mesa.cityofgrace.com.

From using the “Debug Queries” plug-in from Frank Bültge, I’ve found out that I’m using about 14 queries per page–this is with 3 plug-ins installed.

So what I’m doing for my site-map like footer is creating custom loops for each category, listing out all of the pages under them (like in the example Web site above). I have 5 categories in my WordPress CMS Web site with about 5-7 pages within each section/category. When I do this, the number of queries jumps to about 32 queries per page. The code I’m using us pasted below.

I feel like I’m doing these loops incorrectly and generating unnecessary queries. Can anyone help me with the proper way to code my multiple loops?

I’m reusing the following code 5 times in the footer for my “site map” and it’s generating 18 more queries.

<ul class="footer-lists">
<li><a href="#" title="" class="bold">About Me</a></li>
<?php
$categories = array(7);
if ($categories) {
	$category_ids = array();
	foreach($categories as $individual_category) $category_ids[] = $individual_category->term_id;
$args=array(
		'category__in' => $categories,
		'showposts'=>12,
		'caller_get_posts'=>1
	);
$my_query = new wp_query($args);
	if( $my_query->have_posts() ) {
		while ($my_query->have_posts()) {
			$my_query->the_post();
		?>
<li><a href="<?php the_permalink() ?>" title="<?php the_title(); ?>">
  <?php the_title(); ?>
  </a></li>
<?php
		}
		echo '</ul>';
	}
}
