You can read much faster if you can break yourself of the habit of sub-vocalizing words as you read them. I think most of us were probably initially taught to read aloud, and spent far too much time doing that during our schooling. If you can instead read the entire word as a logical unit, rather than having to break it down in your mind into syllables or individual letters, you can read much more quickly. This does seem to require a pretty strong visual memory to be able to store and recall the "look" of a word, and you also need to have a relatively extensive vocabulary, or else you will be bumping into unfamiliar words that you have to look up or infer from context. That's what works for me, anyway. YMMV
