    Pinned memory makes driver very happy

      This is odd; I have a few relatively small intermediate buffers that I used to create on the device only.

       

      I will now be needing to process these buffers on the host, so I tried creating them with pinned host memory,

      in preparation to map them.

       

      For some strange reason, performance has improved significantly.

       

      I'm not one to look a gift horse in the mouth, but can anyone think of an explanation for this phenomenon ?
