I'm using Draktable and it takes a long time to export all my images. Something like a few hours since there are plenty of images. As I'm monitoring my CPU usage, I do see Darktable making use of my all CPU cores for its GUI. But when it comes to exporting, it only uses one core. Is there any way to ask Darktable to use all my CPU cores?
Here are the versions that I'm using:
Darktable: 2.4.2
OS: Kubuntu 18.04
Here's a screenshot of my Darktable config:
BTW, I do have a GeForce GTX 1080 ti as well. But it is not used at all while I'm exporting images!
