Hi,
I'm back again with this issue after a while and I want to add new one.

As far as I understand it, osb should be a 2.0 replacement for bin in 
1.8 (?).
While loading large and complex geometry (about 90MB osb file), I have 
found that it takes about 10 times longer to load osb crated from same 
geometry as bin in 1.8. Does someone else experience such issues too or 
there is something wrong with my build...?
(I have measured time for SceneFileHandler read call)

Kind regards,
Robert
