the new vm does not seam to have an effect (this is without  
LookEnhancement):

3.7.4b1, 3.8 image:
11076
10100
10074

3.8.8b6, 3.8 image:
11491
11399
11682

3.7.4b1, 3.9 image:
7745
7706
8282
7938

3.8.8b6, 3.9 image:
7877
7951
7876
8500

Initially, I came up with these numbers because I suspected  
LookEnhancement to have negative influence on performance, which not  
seams to be true. A nice finding is that the performance improvements  
in 3.9 are remarkable.

Cheers,
Adrian
