hi, it seems you need most of your computation time to create thumnails.. there are a couple of tweaks you could do in your config/darktablerc to speed that up if you don't care about thumbnail quality too much. the problem is, when using jpg as input, most of these don't apply (since there's no small embedded thumbnail to be pulled out of the file and faster demosaicing options etc don't apply either).
