Performance regression in baking light with enlighten

Anyone noticed a performance regression with baking light in between 2017 and 2019?

I havent clocked it, but it's way slower. We have a scene that takes about 2 hours in 2017 and now it's beem going for 3 hours and it's only on bake direct. So final gather etc is not even done yet.

 

And afterr a few hours when final gather do start I get this

 

After several of these errors the scene did bake and finnished sometime during the night. (need to clock the bake)

But there are some strange errors I see. For example

Here is 2019.1.10


In 2017.4.30

 

I clocked one of our smaller scenes

Unity 2018.4.30 - 00:11:09.6869982
Unity 2019.1.10 - 00:11:42.5165017

So 5 procent slower. Not the same perfomance reduction it seemed like yesterday, Will try some more with larger scenes
