I return to this post to point out that this problem persists in Softimage 2014.

In summary, subcomponents operations (on points edges polygons, etc.) on any object of the scene are slow...
...When I have some ICE Tree with "instance shape" node which reference a group instead of object directly.
You can compare the reactivity of translation operation on points of object and same on object mode.
I had already report this behavior on Autodesk page report but haven't any feedback about this point.
Is someone already seen a real slowdown on subcomponents operations ? It's probably your "instance shape" node which reference a group object
Now I have to prohibit me from using the groups directly in an ICE Tree.
Thank you for your attention.
