[Plugin: WordPress Mobile Pack] overloads the server

i have been told by my hosting provider – hostgator – that this plugin is causing overloads on their system. Here is exactly what they told me:

“You can tell them that the processes and requests to the plugin overload the linux server you are on. This should be enough to give them a starting point. “

Since they are one of the largest hosting providers and i have over 100 websites of mine and clients with them, i don’t have an alternative to move the sites.. and since i put this plugin on over 50 blogs, i’m concerned eventually they will shut down all of my sites until i remove this plugin..

can you please help.. maybe it’s just a setting i’m missing?
