It is a very simple program but numerous folks over in 'comp.benchmarks' have run it on their systems and it would be interesting to see where the NEXT 040 fits. Perhaps NeXt did not use the Motorola math function library ? The math function library from Motorola I am assured is faster than a 33 MHz 68882.
