I try to make some leaves and vegetation but the render times are tooooo loooong (20 heures for a few bushes and trees).
Is there some setting to optimize that and must we wait for a better integration by next limit

Must have more info, check if your plants and leaves are hi-poly... Where do these models come from? Onyx or something similar? Evermotion?
Hardware specs?
Modeling app? Is it possible to use Maxwell proxies?

essentially xfrog and leaves are made with alphach annel. That's why rendering times are so long like in vray ?
For info, in fry the same scene whith the same ernvironment hdri and the famous S5 (SSS single sided), it takes 1h30 (9h30 in maxwell).
That's why, i'm so surprised by this huge difference.

Can you post a render?
How about a screen grab of your thinSSS settings?

Nothing fancy in the settings.
Very tiedous to master though a little change in the slider or texture and the changes of the result is very different.
