In your front-page.php

<div id="hottags" role="main">

<h2><?php _e('Hot Tags'); ?></h2>

<p class="frontpageheatmap"><?php bb_tag_heat_map(); ?></p>

</div>

bb_tag_heat_map() is what you want to avoid.

A function call means some processing, involving database queries etc. You surely wants to remove all the unused stuff for top notch performance
