I just ran your site through Pingdom – it has a load time of 3.67 seconds.
Can you activate one of the default themes now so I can run a comparison check?
In Pingdom you can check out the “File requests” section which breaks down each part of your website when it loads. It looks like the majority of the load time is coming from your server itself. Who are you hosted with?
