Well, first, "atmosphere" is an obsolete feature, it has been replaced 
by "media" in POV 3.1. POV 3.5 is currently in beta, you really should 
upgrade to at least POV 3.1.
Anyway, the reason it is slow is the extra calculations for doing the 
light scattering...you pretty much have to choose between fast rendering 
and no light beams or slow rendering with visible beams. However, the 
MegaPOV unofficial patch and the POV-Ray 3.5 beta have additional 
sampling methods that can let you get away with much faster settings, so 
you may want to check them out.

Or you might be able to fake it using a semitransparent cone or a 
transparent cone filled with emitting media (which will render faster 
than scattering media).
