problems with the speed render

[Grafikus]

hi guys!

please answer the question.

I hope that I will answer correctly
but there is a small problem, I'm not an English )))
but I hope to understand.

if I have  very many lamping in my scene, just a lot, what can I do? if you have a lot of light bulbs they are affected by the speed of rendering very much! I created the exterior, and there was a lot of street lights, 200 pieces(corona light) and it is very much a halt render, render in primary rays walked hour, Further, I did not even continue.. geometry of many - grass, building on the background ... ,but everyone say  that the corona render despite of the number of light sources and geometries, quickly calculates all!

ок, as anything I decide the issue in this scene, is to remove most of the lamps, but a friend in the future would be so that all the lamps will need to leave?
What if there is any solution to this crown render settings? or what some other solutions?


my computer configuration - core i7 3.60, geforce gtx 780 ti, ram 32 gb. 

Thank you.

Are your street lamps with some kind of "glass" with caustics on?

Try to render the same scene using only white materials, then check if the issue is still there.

Probably you didnt even bother to check your albedo settings, that are crucial for the speed as far as I know.

I am assign white material  all geometry in the scene, but it is dont help me! rendering is also long! I said wrong, I have in the scene  is 400 light bulbs, but it still should not hinder the scene. Crorna may have a certain limitation with rays? because when i paste 150 lamps then is normal with the speed!!! types of lighting my scene - 150 corona lights sphere; 250 - standart photometric lights with corona shadows.

Im not an expert, someone once said that instanced geometry can really slow down the render.

May that be the issue?

[Grafikus]

in the scene should not be instanced objects? all convert to proxy?
when i do copy the oblect i do instanses but  i must do copy? tell me right way plz?
