[solved]site is very slow after switching to hostgator

[eluser]swgj19[/eluser]
I pin pointed where the problem is by disecting every folder. When I upload a fresh install of Codeigniter, everything is perfect. Even when I replace the controllers, models, and views in the fresh install.

Here is where the problem lies:

When I upload the core and libraries directory, that is when the website slows down.

So looking further. In the other scripts, the My_Controller is not extended. In the site that is slow I have a backend and frontend controller in the libraries and extended My_Controller in the core.

I know that this is the problem, I just do not know how to fix it without breaking my auth system.

And why would this work with godaddy, but not hostgator?
