Core Text Performance Problem

I have been following a iOS tutorial on raywenderlich.com, called "How To Create a Simple Magazine App with Core Text" LINK

The App works great on the simulator, but when i build it for my iPad 1G, the scroll view is not fluent at all, the performance goes down, 开发者_开发技巧and the view becomes useless. I have been trying to get help at the raywenderlich.com forum, but with no luck.

Is it a general problem with Core Text or what do you think?

When trying to debug lag issues, try and find similar apps on the Store that are doing similar drawing. If your performance does not equal that level, then your code can obviously be improved.

For instance today, I was coding a UITableView, but when I ran it - it was not fluid in scrolling. I just knew that something wasn't right as the hardware could obviously handle it; looking at scrolling performance in the Music app for instance. So I used the profiler tools and eventually tracked down my error.
