When most of the elements of an union share the same texture(s), it's better to assign
that texture 
to the union instead of each element. This will save memory and can save some time. In
your case, 
you can assign Blau and InnenAufbaut to the whole thing as it looks like the ones that
are used the 
most. Saving memory can prevent the use of the swap file, thus providing dramatic
speed improvement.

You use loops to create unions of 100's to 1000's objects, spliting those to only
contain objects 
that use a common texture can help. Use several similar loops, one for each texture
familys. Don't 
forget to reinitialize the random streams.

Using layered textures increase rendering time, look if you can create single layer
textures to 
replace the layered ones.
