For reading anything of length, I like to split horizontally into three balanced windows [1], put the buffer in all of them, and `M-x follow-mode'. At that point, I get a nice columnar display that makes better use of the screen real estate.

If you do this, you can make paging snappier and more predictable like so:

  (setf scroll-preserve-screen-position t)
  (setf next-screen-context-lines 0)

[1] That is, three windows of the same size side-by-side.

`C-x +` (M-x balance-windows) for those who don't know . There's also M-x balance-windows-area.
