We have migrated some collections to DPS 2015. One of the things we notice is how slow the new viewer opens every article.
In the current viewer, you can browse trough the whole edition (30-50 articles) really fast just a short time after the initial download has started.
In the new viewer, every article takes time downloading, giving the reader the feeling he is in a really slow app. And the limitation of only downloading the next four articles isn't really helping.
An ordinary edition of 30-50 articles is usually between 20 and 40 megabytes, so download time itself should not be the problem.
