Hi,
I'm still struggling with migrating from old OSG 3.2.1 to the latest
developer release, now 3.5.8.
I stumbled upon a rather serious performance issue here. When loading an
OpenFlight model with a large number of polygons, the optimization
carried out in the OpenFlight plugin is unacceptably slow in 3.5.8. It
seems the culprit is MergeGeometryVisitor.
Here is an example with 150 000 polygons, it takes about 12s to load in
osgviewer 3.2.1 here and what feels like forever to load in 3.5.8:

Has anyone seen this before? Any ideas how I can get it to behave like
before?
Regards,
Andreas
