Hi Markus,
First thanks for sending the logs. I'm replying here so that others
can pitch in with their own suggestions.
You're welcome!
The interesting parts of the old and new loaders logs are:

Should just need to do:
export OSG_OPTIMIZER="DEFAULT COPY_SHARED_NODES"
osgconv myfile.flt myfile.ive
I have done this for my database too. Here's the result:

This leads to the following new performance table:
Position 1:
OSG version | fps | Drawables | Vertices
-------------+-----+-----------+----------
1.0 | 30 | 5321 | 226508
cvs-old | 33 | 5321 | 226508
cvs-new | 23 | 5320 | 226503
cvs-new-copy | 27 | 5322 | 226476
Position 2:
OSG version | fps | Drawables | Vertices
-------------+-----+-----------+----------
1.0 | 50 | 3037 | 179605
cvs-old | 51 | 3037 | 179605
cvs-new | 40 | 3033 | 179579
cvs-new-copy | 43 | 3035 | 179603
