Hey everybody

A while back I downloaded Odoo 8 on Ubuntu 14.04 and installed the eCommerce module.
I've developed this on a local machine and I've now put it online on a server.
Since I've placed the shop online I am noticing a severe waiting time (of over two minutes) after clicking on the pay now button.
You can see the delay here: http://i.imgur.com/QIBPGlg.png
And the details here: http://i.imgur.com/PMjaAZ3.png

Could anybody give me any information or hints about how to solve this or what causes this?
