I mentioned this a few months ago, but I am not sure where it went. When I use progressive, sending it to my Render Pro 2, my render times are much higher.
Do you have any render elements? Those tend to slow down the progressive sampler a lot.

Yes, I do. I’ll disable and see if that changes things.
Are in GPU mode? If yes, see if you get the same slow down with CPU version.
