Hi,<br>
<br>
I'm still struggling with migrating from old OSG 3.2.1 to the latest
developer release, now 3.5.8.<br>
<br>
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.<br>
<br>
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:<br>

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