That's strange. It should load in less than 1 second most of the time. Could you put your board in debug mode and show me the results of an explain=1 on that page?
In case you're not sure what I mean, you would open your admin/config.php. Right before the ?> at the end of that file, add the code:
$debug="1";
Then upload that file and go to the url -
http://cross-x.com/home/indextest.php?explain=1
If you wouldn't mind doing that and pasting the results of that page here I'll be glad to take a look and see if I can figure out why it's loading so slow.
