Hi Marcel,
yes, I was referring to gvSIG Desktop.

...or a loading image/icon or more simply a waiting cursor.

Your test is very interesting and useful for debugging, I think. The 
bottleneck should depend by a combination of these factors, plus the 
particular used driver. For instance, I was not able to load a DXF layer 
of 60 MB on gvSIG Desktop 1.10 today.
