Oh yeah you're too right !!! The main performance issue was due to the kind of the mouse plugged on the workstation(s). The Logitech MX-Revolution M-RBQ124 has a third button that eat all a CPU core when using it with X11 (and Python VTK). I think there could be another performance problem because my test is running a little slow in this kind of MacPro, so I'll try Shark as you advised me ;)<br>

</div>It could be lots of things. You could measure what the CPU is doing by<br>
using Instruments or Shark.<br>
