Page turn delay

I am experiencing delays when moving between pages in my book (this happens both when I click a button I've set up to move to next page, and when I set up an action to jump to another page).
In Interact Builder-Interact mode the delay is about 1 second.
In Interact Player the delay is about 2 seconds.
Is this something that will improve once the app is published to the iTunes Store or Android market? The kids testing my app are frustrated with these delays and are losing interest.
Other (non-Interact Builder) kids apps that I use respond pretty much instantaneously. I also looked at the "About Airports" app built with Interact Builder, and the pages take about .5 seconds with a curl effect.
My book is 27 pages, fairly simple animations, 46 MB.
