I'm probably being a little loose in my use of the BITBLT designation.
What I really mean is XLoadImage (with and without various logical
operators set in the graphics context) since this is the bitwise display
operation I use the most.  At one time I was running with the GX board
unintentionally disabled due to an installation error so I managed to
get timings for image loads both with the GX board enabled and disabled
under OpenWindows 1.0.1 and found no measurable difference.  Of course,
now I mention it, I can't find my notes.
