Personally I think Speed Reading is a vital skill for anyone in this so-called information age.
Speed Reading is a collection of techniques, understandings, adjustments in behaviour and practiced abilities. It's not just a single technique for increasing words-off-the-page speed (although that's what the headline figures might have you believe).
Also don't get too hung up on the massive claims of some speed reading proponents. If you can get 10k WPM great! I think most speed readers get around 1k WPM without loss of (or often increased) comprehension. Obviously with highly technical material, especially that which you're seeing for the first time, the words-off-the page speed is not going to be the bottleneck, but there are many aspects to speed reading that improve comprehension at any speed, and which often work better at higher speeds (imagine listening to someone who speaks very slowly - how much harder is it to follow them - and avoid being distracted!).
I also believe that what we learn from speed reading can be applied even to writing code. I have written a series of blog articles on this, which are now being prepared for publication in a C Vu - a developer's journal.
