Those render times :?

Could someone from NL explain why is V4 slower than V3 (CPU engine) ?
There weren't announced any new features/changes for CPU version and I expected at least same, maybe faster, results. Not slow like this with such a easy and simple scene.
I don't want to imagine, if I render for 4-5 hours in V3, in V4 it will take what, 6-8 hours... ?

Thanks seghier for your tests.

Ugh, so sounds like V4 is notably slower than V3 on CPU, if V4 even had OS scheduling advantage over V3 and V3 still won.

WTH?!

Yes, no mayor changes on CPU engine. The performance issue if a deploy issue. We are working on it.

Have you tested using Constant Dome only? I mean the contrast difference... Looks like gamma to me, we will check that.
