It could certainly add an overhead to the ambient calculation if it  
attempts to predict indirect shading across the curved surfaces.  You  
could use the genampos script to see where the calculation is  
expending effort.  See the resources page on my site (link below) for  
a 'Technical Note' on the use of the genambpos script.  The script  
should get installed by default with the rest of the Radiance  
executables.
