John,

        I'm the guy who ran the stream benchmark on the Sun Ultra 1/170 just
before Christmas. This was done on a pre FCS beta system. Recently I have
rerun the stream benchmarks on my brand new Ultra 1 with better results.
Just thought I'd let you know.

Two runs are included one for 91Mb and one for 160Mb.

Run on a Sun Ultra 1/170 @ 167 MHz. 196Mb of memory.
Compiled with SPARCompiler FORTRAN F77 V4.0.

Options: -fast -O5 -xarch=v8plus

Regards,
Tore Ottem
