By default using method 3, this should stay at 1.

Raise this instead, samples 25 interval 1 is MUCH faster than intervals 5 
samples 5 for the same final number of samples.

Your media is prety faint, try raysing emission some.
Only 40% of your radius emit, the rest been density 0, combined with the low 
emission makes it hard to see, especialy if the background is light.
