An excellent post but I don't see how you can conclude that this test wasn't
fair. I think you've possibly come as close as you can get to a fair test for
your application by optimising for Performer and GVS and as far as I can see
the reasonable conclusion is that with Performer you can better utilise the SMP
and that on some platforms & some applications this has an impact upon
rendering performance (not exactly news). This is an area where SGI is very
strong and is often a factor in the choice of platform.
I think comparrisons of different rendering software on a specific Silicon
Graphics platform can be usefull provided the benchmark is tunned for each, up
to date and you bear in mind that speed isn't the only performance factor. I'm
thinking mainly of features here but ease of use is important to a broader
community, as are portability and open standards.
I would also suggest that as more vendors adopt the OpenGL rendering
specification that cross platform benchmarks will become more usefull although
this is open to gross abuse(and ignorance), and many will never adopt OpenGL.
In any case, many of your objections to this approach would still remain valid.
Rgds,
Angus.
