So, that gives the performance of an IBM 3090 with VE as 13.8
MFlops.  http://museum.ipsj.or.jp/en/computer/super/0005.html gives
the maximum for the VP 400 (which I worked on) as 1142 MFlops, which
I can safely assume was single precision, so around half that for
maximum MFLOPS for double.  This is apples to oranges, of course
(theoretical speed vs. actual benchmark) but still shows that my
memory was not far off - the VP was the _much_ faster machine,
and IBM didn't even come close in performance to what
the Japanese were doing at the time.
