Thanks Artur, Chris, and others for your assistance. Your testing and
suggestions are very appreciated. It seems that there's too much geometry,
and too much transformation (both factors seem significant).
Thanks,
Geoff.

FYI, it runs at 1.4fps on a PIII700 notebook with ATI Rage Mobility AGP
2x, 8MB and 12fps on an Athlon 900, AGP 4x, Gforce II GTS 32MB
When I reduce the divisions to 4 the notebook fps goes up to 5.5.

One thing for sure is to rotate view, not all objects. I've done a bit
of profiling on program and it was transform3d compute bound. When I changed
all mouse behaviours to OrbitBehaviour on view, performance increased about
two times.
Second thing I've done is switching from directx to opengl. Performance
increased threefold (six times compared to original measurement).
I hope it is enough for the moment. If you would like to make it faster
by another factor of six, please tell :)
