Yes. I have tried it multiple times and the results are quite astonishing. 
You have to keep in mind however that this is done on a barebones scene. 
Just one main sphere with a bunch of differenced spheres, no AA, simple 
light_source and so on. Whatever else you put in your scene does not profit 
from this trick. Having said that, what I tend to do is when I have objects 
that are the result of time consuming calculations I try to always store 
those in external text files and later #include those files.
