need to cut down load time of a booking system with JQM and ajax disabled

Hi, I'm trying to mobilise a hotels web booking site. I've 
got everything working although i had to disable the mobile 
ajax to do so.

I had to do this as our site keeps a session id within the 
url bar and uses it every time you navigate to a new page 
to retrieve relevant information, whether a member logged 
in or just the current details.

However with this disabled the load time between pages is 
about 20 seconds longer than if I wasn't using JQM at all.

From what I've read, with the ajax disabled, this means 
every time i load a page its reloading all of the javascripts 
each time, which takes up a fair amount of space.

I'm not very familiar with javascript but is there a good way 
of cutting down the files or reducing the load time?
