Dolphin is quite fast now, if properly configured, but it is strue that it may see improvements on content side - less images, optimised JSs and CSS, minifying. Some require more work, some could be done, but are left in order to preserve easy editing for webmasters. You know that 7.0.3 has been significantly improved and the next step is 7.1 which would have content/layout optimisation throughout.

Interestingly, I tested a bunch of competition products demos and all of them resulted with similar see more %%... you just have to realise that feature-packed CMSs inevitably return lower results in demos, since they display too much stuff on their homepages. Clients are supposed to pick features and optimise for their liking - then it works much better.
