Hi Dario,
> Hi,
> I'm experiencing for a very huge performance issue using models with bones (and animation). Look at images attached. The little cute dolphin WITH bones (animation stopped) show 107FPS, the one WITHOUT bones (animation stopped) show over 3400FPS. Used in a simulation, performances issue is very annoying. I think the presence of bones produces this issue.

There is likely no actual problem. What happens if you add a second , a 
third model etc?
Simply comparing a static mesh with a essential zero overhead in 
traversal with something that needs traversal says nothing about the 
performance in a real world scenario. Please check the stats (by 
pressing S in the osgviewer).
Chances that adding another model with bones will not decrease 
performance at the same scale is high.
Also providing more details on the version, your computer and possibly 
some sample code might help to get some more information and guidance.
