Sir,
Please find below the results of running your streams package on:

HW: HP Kayak XU (dual Pentium Pro/300MHz).
        Timecounter "i8254" frequency 1193182 Hz cost 3070 ns
        CPU: Pentium Pro (686-class CPU)
          Origin = "GenuineIntel" Id = 0x634 Stepping=4
          Features=0x80fbff<FPU,VME,DE,PSE,TSC,MSR,PAE,MCE,
                            CX8,APIC,SEP,MTRR,PGE,MCA,CMOV,MMX>
OS: FreeBSD 3.0-980304-SNAP
        Configured with SMP support
Flags: gcc -o stream_d stream_d.c second_cpu.c -malign-double -O6 -lm
        gcc version 2.7.2.1

-------------------------------------------------------------
This system uses 8 bytes per DOUBLE PRECISION word.
-------------------------------------------------------------
Array size = 3000000, Offset = 0
Total memory required = 68.7 MB.
Each test is run 10 times, but only
the *best* time for each is used.
-------------------------------------------------------------
Your clock granularity/precision appears to be 7812 microseconds.
Each test below will take on the order of 195312 microseconds.
   (= 25 clock ticks)
Increase the size of the arrays if this shows that
you are not getting at least 20 clock ticks per test.
-------------------------------------------------------------
WARNING -- The above is only a rough guideline.
For best results, please be sure you know the
precision of your system timer.
