I downloaded and tested this software on my PB 867.
If I'm reading your chart right then, yes, your performance
based on these numbers is less than I'd expect.
I dont have a G5 though so I dont know if the impact of
some conversions necessary for the G5 are this significant.
However, if you are running other OS X apps at the same time
then your results are going to vary wildly.
Even on my quiet PB, two sets of runs would very a bit.
I'm not sure how familiar you are with Windows and Windows services.
But you might find signifcant improvements to be found if you selectively
disabled unneeded services.
Do so with caution of course or you could lose functionality or destabilize
your system.
I tested in configurations comparing 256MB with virtual memory of 512MB,
512MB with no virtual memory, and again after uninstalling VMWare
and taking out its services.
Top performer did not surprise me was 512MB with no Windows virtual
memory. 256MB with virtual memory was up to 20% lower.
After losing the VMWare services performance went up about 10%.
Nothing special about VMWare here, its just an example of what impact
a background service can have - even when it wasnt meant to be doing
anything.
In VPC I aggressively cut back the services I have started unless I
explicitly
need them.
To spare your G5 embarassment here, I wont say how many factors greater
the little 867MHz PB reports in MFLOPs.
I've got to hope your system is capable of significantly better performance
here.
