what is wrong?

Send us the file and we will check what is wrong in your settings
The new engine is physical now, so it’s a little slower but not that much

Hello 
1- I think the time depends on good way of equipment characteristics. To the extent we have an excellent setup, the results will be faster.
2- A lot depends on the materials and used parts, glass, mirror, reflection metals are elements that increase the cooked (time) in Artlantis, and Render IN
3- dream that Render IN 3, will have the same speed Render IN 1 is keep dreaming without waking

Abvent in my opinion, the new generation of products, seeks to have better results.
and one way to achieve this is by increasing the render time, with the new engine.
physical engine on continuous testing and adjustments for developers 
As always and that to me is incredible to have a small Artlantis in Sketchup
… I mean, Render IN, in Sketchup … amazing
Perhaps in the future, not distant, we can find in Render IN, or Artlantis, what we dream 
At the moment, the issue is not angry … is to adapt and enjoy this extraordinary engine, with its flaws and benefits
in my tests with the scene, we:
10 minutes, original scene
9 minutes
As always, using the Purge plugin, and CleanUp, save and then renders
Is slow? if it is … possibly my machine, materials, missing adjustments to the engine, and the relationship, Sketchup - Render IN
But little by little we will make progress, sure that if
Timeless, calmly, everything has its time
luck, a hug

pd: sorry for my English
