Dumb question, but why is it abbreviated as LS_D_ when it's spelled loop stream _b_uffer?

  It's actually spelled Loop Stream Detector and it dates to the Core 2 processor family which is circa 2006. The LSD is described in section 3.4.2.4 of the Intel Optimization Manual, Optimizing the Loop Stream Detector (LSD). AnandTech describes how it works. https://www.anandtech.com/show/2594/4 https://www.anandtech.com/show/2594/4

    Yeah that's right. Not sure where I picked up the term "... buffer" but a search shows I've been using it for a while.

      Probably was just easy to mentally conflate it with Decoded Stream Buffer. It compresses better if you just change Detector to Buffer :-)
