Unfortunately, there's nobody near with Unix installed, so I can't make a quick comparisson. We would take up Unix usage and investigation if we were 100% sure that it would decrease calculation time greatly. Using /tracking/verbose 0 indeed saves time greatly. With usaege of verbose 2 I had about 5 hours of calculation. But as I understand, /tracking/verbose 0 turns off only displaying the tracking information, though it's calculated anyway. Is there any ability to turn off some part of tracking calculation if I only need the quantity of deposited energy? Or the information is needed for Geant to perform the full calculation? By the way, maybe I've constructed detector not optimal? Here's my geometry:

I have a source of gammas, radiating isotropically. It's placed 10 cm from side of NaI cube. Energy deposition in NaI is needed.

|-----------------------|--------|
|                       |        |
*--galactic----------------------|--NaI-----|
|                       |        |
|-----------------------|--------|
<---------10 cm-------------->

* - posititon of source of gammas

So I've created the world volume box filled with galactic material (vacuum) and put NaI box inside of it. Is it correct? Or maybe some optimisation possible?
