Thank you all for your comments. The loading of textures could be a good explanation for the slowing down. The original scene is more complex, with many textures, and take several minutes to make the slowing down disappear (instead of some seconds with the attached scene).
However, the PC I use is really powerful, and the textures used are dds files (which are really efficient for the loading). I have 39 Mo of DDS textures to load the complete scene...which is really correct.
