JQM App slow on BB Torch 9810

I'm developing this html5 app using jqm in order to get better at mobile web. Now I own a BB Torch 9810(the 1.2Ghz processor one ) and when testing the app on the phone. The navigation is so slow(transitions are set to none, the click handlers some times don't fire( clicked objects get the highlighted theme so I know they were clicked), at times takes 3-5 secs to fire which is just crippling slow. Animations are also slow, ie, the flipswitch widget, the animation there is choppy, not fluid at all.

I've run this app on my bro's and sister's iphone 3gs and galaxy s2 respectively and it is so much better, actually pretty damn responsive on their devices. Not that way on my BB. 

So is this a problem with the framework or BBerry phone(my phone for example runs yahoo's news mobile site very fluid and fast, so I'm thinking it's the framework.
