Different e-book formats require different computing power. So, it's not fair to compare a e-book format which is capable of representing compilcate layout to simple txt file.
Finally, if the reader software preload next page in the background, users will feel page-turn much faster. Based on my experience with iLiad, the speed of page-turn can be 5 secs (without preloading) or 2 secs (with preloading). That means, fast page-turning is only the best case, not average case.

However, it's completely fair from a user experience point of view. When I read a paper book I don't worry about whether it's a DC Absolute (oversize archival quality hardcover comic collection) or a cheap mass market paperback when I turn the page.
Yes, page turn rates are based on more than just the display controller, and may vary significantly on the same device depending on file type, but for the average reader that doesn't matter. What matters to most readers is whether the delay normally bothers them or not.
It's the average that really matters, not the extremes. If it normally feels responsive, but occasionally bogs down, that's one thing: if it normally feels sluggish that's another. Average page turn speed is one of the best ways we have to judge that.
It doesn't have to be a fair benchmark.
