Mia Culpa! Your response prompted me to look into this again so I checked my Libraw 0.22 compile flags and found the Libraw VS project did not have the /OPENMP flag set for Debug mode. This accounted for the big performance difference (on a 16 core machine).
Hi Alex.
Thanks for looking into this.

Very sorry to have you chase a ghost.
I'll be more thorough before posting next time.
