How can I investigate about this slowness?
I used Java VisualVM to test Sweet Home 3D under Java3D 1.5.2 and 1.6.0 in the same conditions, and it didn't reveal anything that could explain this slowness. Would it be correct to conclude the GPU load is much higher? How to tune the OpenGL context? Did any other person complain of such slowness under Linux?

If you want, you can try it on your side:
- download the Jar executable http://sourceforge.net/projects/sweethome3d/files/SweetHome3D-5.3.jar
- download a large enough home like http://www.sweethome3d.com/examples/SweetHome3DExample10-FlatWithMezzanine.sh3d
- run the Jar executable, open the downloaded example and drag and drop the mouse pointer in the 3D view. You should see that while dragging, the animation isn't very fluid even it's still usable.

If you want to compare with Java3D 1.5.2, open a Terminal window and run Sweet Home 3D with the -Dcom.eteks.sweethome3d.j3d.version=1.5.2 Java option:

java -Dcom.eteks.sweethome3d.j3d.version=1.5.2 -jar path/to/SweetHome3D-5.3.jar

Hope you can help...
