X being slower could be caused by lack of hardware acceleration, at
least for some combinations of cards, X servers, and so on. Most OSes
ship with blobby acceleration, OpenBSD doesn't but loses out on some
performance[1].

I do agree that, in particular, the disk access scheduler does not seem
optimized for desktop use - I see the same while doing a backup, or even
just untarring/cvs up-ing.
