Hi,
Didn’t found anything strange. Can you clear the products in trash and delete the menus you are not using?
In the speedtest result in Pingdom tools in can see that the site loaded in 5.21 seconds but lost almost 1.38 seconds making the initial connection(this time should be at least 5 times faster). This would take your site loading speed to 4 seconds what is already pretty good.

Regarding that initial 1.38 seconds check with your hosting why is taking that time to establish the initial connection.
