how timely.

What's the difference between the R2000 and R3000 at an architectural
level. A local person debating between DEC and IBM machines found that
the DS5000 (with an r3000) gives ~15MF on addition, which he found
hard to believe.  Taking a linear scaling from a DS3100 (R2000 based),
I'd agree, since the DS5000 seems to be 75% to 100% faster than the
R2000, from which I can pull about 3MF, downhill with a tailwind.
