Button timeout

I was using Tweetmeme module in my site, but I always received a timeout error. My server performance is not the problem.

Now, I've taken the following approach in my node-blog.tpl.php template:

  <?php global $base_url; ?>

  <script type="text/javascript">
    tweetmeme_url = '<?php print $base_url; ?>/<?php print $node_url ?>';
  </script>

  <div class="node-title">
    <?php if ($page == 0): ?>
      <div style="float: left"><h2><a href="<?php print $node_url ?>" title="<?php print $title ?>"><?php print $title; ?></a></h2></div><div class="tweetmeme tweetmeme-button"><script type="text/javascript" src="<?php print $base_url; ?>/misc/button.js"></script></div>
    <?php elseif ($page != 0): ?>
      <h2><span style="float: left"><?php print $title; ?></span></h2><div class="tweetmeme tweetmeme-button"><script type="text/javascript" src="<?php print $base_url; ?>/misc/button.js"></script></div>
    <?php endif; ?>
    <?php if ($submitted): ?>
      <div class="submitted"><?php print $submitted; ?></div>
    <?php endif; ?>
  </div>

You may see it in action here.

What could be the problem?

Thanks in advance!
