Since the monitor's frame rate is 75 frames per second, there is no
way/reason to draw more than 75 frames per second, even if your application
takes less than 1/75th of a second to draw a frame. All your test shows is
that your application takes less than 1/75th of a second to draw a frame
whether you use IRISGL or OpenGL. It doesn't say how much less.

Note also that 3 x 25 = 75 (i.e. it took three 75ths of a second to draw a
frame with OpenGL on an Indigo2 Extreme) and 2 x 37.5 = 75 (i.e. it took
two 75ths of a second to draw with IrisGL).

Try using the performer stats or use the "gr_osview" program.
