The dynaview, as I understand it, prevents portion of the page to which you have not yet scrolled from rendering. This appeared to work, as you could tell because when you paged down there would be a pause before the page became visible. But it didn't seem to help performance. The dynaview version is still online, btw.
For that matter, I found the epub sample to be fairly slow, and it's only an excerpt from the book. It would have been interesting to see what the entire book was like, but I was unwilling to sign up for an account to purchase a public domain book that I've already read. As an actual user of ebooks, I'm not sure the epub fulfils users needs. The epub is impressive, but probably not worth the overhead. I regularly read a huge book on TW without difficulty. What the world really needs is a format with some sort of block-chain registry built in so that you can share and exchange commercial ebooks just like you can real books. In any event, people don't avoid reading because they need better formatting, people avoid reading because they're doing other things. And reading isn't even cheaper. A subscription to netflix will costs you less than a subscription to Kindle unlimited! You can binge watch the entire HP series in a single day, and save weeks of reading! \s Thanks!
