So the thing is that on production scenes with lots of forest objects the Scene parsing becomes slow, im talking 1+m to start. I guess this is happening to most of the artists working with forest and corona, I have tried Vray3.6 and for the scene parsing it just seems Faster, way faster. Unfortunately Cant try the same scene or a newer vray on this topic but sure some one else can do that comparison.
For me its super frustrating when this starts to happen, its always the combination with forest and the interactive is no longer usable
On a medium size scene the times start to show
Regular render time to start the rendering process : 52 Seconds
Interactive render time to start the rendering process : 58 Seconds
On bigger scenes this time gets bigger between the two
Also looked at another topic about itoo forest and corona regarding some implementation to get faster meshes out but there is no response for that topic too..
i can see on trello something about Rewrite of the parsing for the interactive rendering, but its not on v8 so far..
I just have access to vray 3.6 and the starting times are way faster than corona.
I really hope this conversation can take off, starting times and interactive performance is one of the Key points for a good workflow for me.
This conversations should be taken into account:

Attached is a test from Itoo developer showing the time spent for different scenarios, here Corona Loses is slower 15x to 39x times compared to vray.
