Hi Robert,<br>
<br>
Yes, I tried it now and OSG 3.4 loads the model in the same time as
3.2.1 did. I found a few versions lying around here and concluded
that something must have happened with the optimization between
3.5.1 where it works as before and 3.5.6 where it stalls.<br>
<br>
I'll keep digging but please let me know if you find something out.<br>
<br>
Regards,<br>
Andreas<br>

<pre wrap="">Hi Andreas,
Did you try OSG-3.4.x? I'm wondering about when the regression in
performance might have happened.
I have downloaded the file and will have a look.
Robert.

<pre wrap="">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
