Jack, you appear to be saying that the ranking is the important issue, but
that the actually timing numbers are not important. Will you clarify this
for me? 

The web page does not say what the configuration of the "high performance 
workstations" are and there is the possibliity that the artifacts could be 
so large that none of the data is meaningful. If you are saying that the 
"high performance workstations" vary from "a Commodore 64 with a kluged
copy of KA9Q, and another agent ran on an Sun Solaris", you still have not
eliminated the possiblity that the artifacts are so big to make the data
meaningful. [Although, I note that Keynote does not publish the fact that
they run on KA9Q on a Commodore 64 on their web site, so I would assume that
none of the agents really do run on that configuaration.] Could you possibly
get more detail on these configurations?
