A question hard to answer right now - I have to check tomorrow when I am
back on my terminal :) But as I pulled the head-release just some days
ago, this may be the reason why. What I observed was a really
significant slow-down on a very detailed scene. I used very low settings
for -ad in this test (-ad 16) and few ambient bounces (-ab 3).

Cheers, Lars.
