  I still think that this benchmark has not very much relevance anymore with
current computers. If one computer renders the skyvase in 5 seconds and
other in 6 seconds, that doesn't tell anything about which one is faster.
When we talk about times this short, you can't compare computers anymore.
  If you render the scene for first time it may take 10 seconds. If you then
render it again, it may take 5 seconds. Is the computer twice as fast now?
Of course not. There are several things that affect the render time
significantly when the total time is so short, for example the disk buffer,
cache, other processes, etc. You can get very varying times from one
render to another. They have no meaning. One computer may be even faster
than other even if it takes 10 seconds to render the skyvase although the
other one takes only 5. Perhaps the other one had a faster disk or whatever.
  If the scene was so slow to calculate that it took about 1 minute for
the fastest computer to render it, then the results could be relevant. Then
the time really measures rendering speed. If a poor disk cache adds a couple
of seconds to the total time, that has no meaning when the total time is
over one minute.
