Dan,
I think you read this on the performance guide. However, it doesn't say
that the engine knows how to use native threads only on Solaris, it says
that when running in the solaris environment, be sure that native threads
are enabled. Green threads will not take advantage of multiple CPU's. This
seems to indicate that Java 3D will work fine on a non-Solaris multi-CPU
environment (ie NT). Also, I noticed some of the highest results for Bench
J3D for posted by a HP Kayak dual processor 450 Pentium II, leading me to
believe that it most definitely is taking advantage of the second processor.
What I am trying to find out is to what degree....
