One thing I recommend you do is DISABLE the featured adoptable. The method that it uses to select the featured adoptable can use some CPU resources if your site has a lot of hosted adoptables.
In functions.php find and delete:
$conn = mysql_connect($dbhost, $dbuser, $dbpass) or die ('Error connecting to mysql database!');
mysql_select_db($dbname);
$sql_query = "SELECT * FROM owned_adoptables ORDER BY RAND() LIMIT 1";
$result = mysql_query($sql_query);
if(mysql_num_rows($result))
{
while($row = mysql_fetch_row($result))
{
$id=@mysql_result($result,$i,"uid");
$name=@mysql_result($result,$i,"name");
$imageurl=@mysql_result($result,$i,"imageurl");
$currentlevel=@mysql_result($result,$i,"currentlevel");
$totalclicks=@mysql_result($result,$i,"totalclicks");
$owner=@mysql_result($result,$i,"owner");
$content = "<p><img src='".$imageurl."' id='me' alt='Featured Adoptable'>
<strong><a href='show.php?id=".$id."'>".$name."</a></strong><br />
Level: ".$currentlevel."<br />
Owner: ".$owner."<br />
<a href='levelup.php?id=".$id."'>Add more HP</a></p>";
}
}
else
{
$error = "No Adoptables!";
return $error;
}
That should help save some CPU for your site. :)
