I haven't tried pst-solides3d yet (though I hope to shortly), but 
pst-geo has similar issues with slow rendering. Rendering speed is 
improved considerably by converting to PDF, though, so you might give 
that a try if PDF conversion is an option for you. It appears to me that 
the reasons for slow rendering might be different for pst-solides3d and 
pst-geo, so I won't be surprised if it doesn't help, but it can't hurt 
to try....
