I have posted results using other tools.

!Desk_Bogo is written in C, though the source is provided an external
library, "JobLib", is missing. There are hard references to the original
author's hard drive.

The 32bit BogoMips from the Unix Porting Project seems not to be around any
more.

It has been suggested that Dhrystones is a better test, at least the full
source is available for that.

In any case such measurements are only part of the story. I have the
impression that VRPC on Vista is faster than the Iyonix even though
Dhrystones shows the reverse. I have already found that VRPC/Vista can
access its harddrive much more quickly than the Iyonix does.

As an example on start up the Iyonix takes 20 seconds to get to the desktop
and 26 seconds to complete the boot. VRPC/Vista completes in 10 seconds.

Perhaps it is all a bit academic now, the Iyonix is no more, the question
becomes not which is the better but is VRPC good enough for the user's
needs.
