May be worth looking at your media. Do you have intervals set to 
anything larger than 1? Bring back to 1 and adjust samples as needed.
intervals 10 samples 5 is much slower than samples 100 intervals 1.

How many dispersion_samples?

It don't looks like a memory isue, unless you have a ridiculously low 
amount in your computer, as you use less than 500 Mb.
