It used to be quite fast? Seems random now, 2-3 seconds.
Are you talking about the Bible pop-ups when you tap on a verse reference in a book? If so, they are working fine for me.
I can think of two things you can try:
1) Check to see if your preferred Bible is downloaded. Even if it is downloaded, remove it and re-download.
2) Restart your iPad.
Let us know if this helps.
