Overall speed (actually not a bug)
I've given a try to rawtherapee even if I'm very happy with Darktable and I've found a terrific difference in speed between twos.
There is anybody experienced the same?
Using the "-d perf" option, I've tried to change all possible settings (OpenCL on/off, different memory settings, etc) without any significant result.
I've tried also to switch to older versions of DT: no changes.
I'm using a XPS9550 with 6700HQ skylake and a Nvidia 960M. Any hint?

Tobias, it is very difficult to give you some concrete numbers: RT does not have something like "-d perf".
From what I've seen, it seems that RT apply the iop in the order used by the user, not in a fixed order. This causes a smaller lag since when you modify a slider, the sw performs only the last operation. At least this is what I guess..
In any case, I feel my notebook should perform faster than it does. And I'd like to have some performance benchmark against other users/hw.
What do you think about posting a sample picture with a selected set of operations, asking the testers to post their outputs of "-d perf"?
Could this be a good starting point to tune and profile some parts of the code? I'm thinking about another ticked related to OpenGL device priority.
