Drupal Slow loading times I'm currently having a Drupal 6 (because some modules are not available in Drupal 7) site running. But the loading time is very slow(www.hard-dance.org)

Here's what I've tried so far to eliminate possible reasons:


I have looked in my admin panel for problems, and did a cron job manually
I have checked to see if Clean-URLs was causing the site to slow down, it was not.
I've disabled some modules, but no change.


I also noticed that my website is going slow, once logged in.

Does anyone have an idea of what the cause of it could be?
Check size of files folder, heavy images may increase site loading time.
