I'd suggest that you post small working examples in either C++ or a
scripted language (prefferred) that require no data.  Something like
the example I posted.

If speed is bothering you so much it just might be your hardware.  If
you have a lousy video card its likely you will not get any speed.  On
my el-cheapo TNT2 M64 the example I posted is slow (with 2000 spheres)
but is definitely not "dead slow".  Besides its perfectly useable when
I switch to using vtkLODActors.  However its easy to see that if I
used a lousy card (or a very low end workstation) it would be dead
slow.  Rendering does require good graphics performance and thanks to
the gaming industry decent cards today are fairly inexpensive.
