Performance new webshop very slow

[osmanp42]

I recently started a webshop in prestashop. Everything works fine but the performance is very slow. I've enabled and tested everything on the performance tab. I've enabled smarty cache CCC (except Smart Chache Javascript and HTML minifyer) and I am using APC caching. 

First time loading sometimes takes about 10 seconds to load which is very annoying. I've got the best shared hosting at GoDaddy so I would expect the performance to be not this bad.

 

This is what the log says:

Has anybody got an advice for me? This would be appreciated.
