This is what I did, and this is the output of the last lines with higest

I have 6 GB main memory and 2 GB on CPU, so it seems darktable is using
good half of main memory( ~ 3.2GB) and ~640MB on the GPU. Is this a
corret interpretation? I was using a 12 Bit Raw of 16MB from an olympus
camera.
Btw. does "using device -1" for preview indicate, that CPU instead of
GPU is used at all?
Thanks,
F.
