[Bf-committers] The Daily Dweebs: Performance comparison of w/o Motion Blur on Haswells

I added two rendered pictures (153th frame) - http://blender.it4i.cz/rendering/the-daily-dweebs. You can see what is difference between blender's motion blur and embree's motion blur. But I think the article https://embree.github.io/papers/2017-HPG-msmblur.pdf from embree looks very nice.
I don’t know If somebody works on improvement of the motion blur in Blender Cycles? I could look at on this feature.

That render time increase at the end is odd. The fact that it happens with Embree but not BVH4 should give a clue, but I'm not familiar with the implementation. It's also odd that Embree MB is faster.
Maybe all the particles are separate objects? In the native Cycles BVH without motion blur, those would have their transform applied.
