thanks for answering.
my model is a sculpt from zbrush, it's use decimation master to down the sculpt max to 1 000 000, otherwise i start loosing detail. And with the ultimaker 2 can handle 0.02, it sad to don't use it .
but even in 0.06 cura is very slow and stuck for more than 10 mn, sometime never respond so i can't save my gcode.
in comparaison simplify3d slice it in seconds, but charge 99% the cpu, that the behavior epected for extensive 3d operation.

Decimate mesh should lower it to say 10,000 triangles. How did you decimate? Maybe try this:

Cura should *never* be sluggish in normal view. Was this slice view? Sometimes cura is slow in slice view - while it loads all the slices into graphic display.
Cura slices faster with thicker slices (say 1mm slices). And with smaller parts and with fewer triangles.
