There are a couple of super easy techniques you can implement. I got mine from the Tim Ferriss book 4 hour work week. I think this blog by him provides a good summary: https://tim.blog/2009/07/30/speed-reading-and-accelerated-le...

I won't do this for books I want to enjoy such as fantasy and sci fi (although sometimes through the more monotonous parts). I will use a few of these for articles/papers until I get to a part which is more technical. Good luck!
