I find cutting off sub-vocalizing does not help at all, instead it totally messes with how much I comprehend or remember the material I'm reading. Instead I make that little voice in my head go as fast as I can, and it works.

Try practicing talking as fast as you can to a friend, like comically fast - but without making mistakes or abbreviating anything. I used to do this with my sister when I was a little kid all the time, and I have a pretty decent reading speed now. (Can easily finish something like one of the biggest Harry Potter books on a slow Sunday)

As always, heavily technical material takes longer to read. But something like a larger HN discussion thread I can comfortably get through in a couple of minutes. Goodluck!
