different CPU implementations, which have wildly varying levels of

computer performance.
So what is the fastest VAX? Just looking blindly at VUPS:
http://www.netbsd.org/docs/Hardware/Machines/DEC/vax/full.html
4000/96A (Cougar++, KA49-C): 48.7 Vups
6660 (Neptune, KA66A): 150 Vups
VAX 7860 (Laser/Krypton+): 300 Vups
The 7860 seems to be the winner but it is a multi processor machine. Is
the Vups measure per processor?
