When you say "performance hog", are you thinking in terms of the blame map being displayed every time someone clicks "history", or only when they click some specific button?
I'm thinking in terms of the algorithm having to refer to diffs of the page which won't exist unless cached from a previous operation. So it would have to generate them there and then. Diffs are cheap enough, sure, but keep pulling the text records and diffing against them en masse, and we'll notice the spike.
