The problem, is usualy a sparcely filled bounding box. This especialy true when 
you have large sweeping curves forming a narrow tube. Each ray that enter that 
bounding box have to be tested against the sweep itself, demanding that the 
whole sweep be evaluated for an intersection with that ray.
A possible solution is to subdivide the sphere_sweep into several smaler 
sphere_sweep. This way, you have many smaler almost full bounding box, instead 
of one BIG almost empty box.
