Well, surely this is the purpose of the Dhrystone benchmark. Of
course, the quality of the compiler distorts the figure, but at least
you get a reasonable figure with which to compare machines. For
instance, a 8MHz 68000 is around 900 dhrystones, a VAX 780 is around
1500, a 20MHz 414 transputer around 3300, a 25Mhz 68020 around 6000,
and so on.
