How to reduce scroll speed in UIScroll view

I have scrollview in my iphone application. At runtime, I add several pages of content to it, and users can scroll the content horizontally.

I think the problem is here. if the user quickly scrolled it, then sometimes thr will delay the loading of the page content.

Is it possible for me to slow down the scroll speed, is the user trying to scroll the view. I want to delay the scroll speed

hope everyone understood my question Thanks
