CCscrollLayer poor performance

Hi,

I am currently using the CCscrollayer and CCscrollButtons from this link:

I am having poor performance when i have multiple CCscrollLayer buttons on one CClayer and was wondering if anyone else has also had this issue/knows how to solve it .
when on a scroll page with only 1 CCscrollLayer button i am getting normal fps but when scrolling to a page with only 8 CCscroll buttons I drop to 30fps.

Any help would be much appreciated.
