John,

  I got the binary files from your VA web page. I ran the regular one
first, with lots of normal stuff open
and running (Sarafi - browser, and the Mail client) and then I shut
down everything else.... and got
identical results:

Power Mac with the 5200 rpm disk (80 gig) ~1.4 gHz cpu, about one
month old.

  Hardware Overview:

       Machine Model: PowerBook5,3
       CPU Type: PowerPC G4 (1.1)
       Number Of CPUs: 1
       CPU Speed: 1.33 GHz
       L2 Cache (per CPU): 512 KB
       Memory: 1 GB
       Bus Speed: 167 MHz
       Boot ROM Version: 4.71f1
       Serial Number: V740847UP21

Software:

     System Software Overview:

       System Version: Mac OS X 10.3.3 (7F44)
       Kernel Version: Darwin 7.3.0
       Boot Volume: Macintosh HD

============
Stream PPC base . out

-------------------------------------------------------------
This system uses 8 bytes per DOUBLE PRECISION word.
-------------------------------------------------------------
Array size = 400000, Offset = 0
Total memory required = 9.2 MB.
Each test is run 10 times, but only
the *best* time for each is used.
-------------------------------------------------------------
Your clock granularity/precision appears to be 12 microseconds.
Each test below will take on the order of 9310 microseconds.
    (= 775 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.

==============================================================

then i ran your optimized one- PPC601 Opt. out; I don't know if this
means it is optimized for
some Power PC cpu other than the G4 (I know from nothing about the
Macs) It ran a good bit
faster that the first one, but 'way short of the 2000 estimate I saw on
your web page for peak
megaflops. ??
