The VAX-11/780 cranked out about as many Dhrystone as an
IBM System/370 158 which did (apparently) chew
through about
one million instructions per second.

Speaking of Dhrystones.... what is one?
Also, what does the MHz, or GHz, measure
exactly?
I understand MIPS (Million Instructions Per
Second), FLOPS (Floating-point Operations Per
Second) and G-FLOPS (Giga-FLOPS) but the
aforementioned two are a mystery to me.
