One minor comment about your table: the Sun 670 numbers are not particularly
helpful, since the 670 is available with several different types of CPU.

I've run your streams benchmark on some of our newer suns with the new
SunPro 3.0 f77 compiler (no parallelizing). Here are the results.
(code was compiled using f77 -cg92 -O4 -fsimple -dalign -Bstatic)

All in all, the machines were not particularly impressive on this benchmark.

Regards,

John
