[osg-users] Model(s) load ~10 times longer in 3.6.x than 3.4.x series in osgviewer (and my in-house software)

Now tested the model with 3.4 - much faster:

$ time osgconv SquareTest.obj test_34.osgb
Data written to 'test_34.osgb'.

real    0m3.842s
user    0m3.112s
sys     0m0.728s

I've looked at the diffs between 3.4 and 3.6 for the obj plugin, the
only difference that stands out as a possible cause is the use of mesh
optimzer instead of the tri strip visitor.  Mesh optimizer works much
better for modern graphics cards, I wouldn't have expected such a slow
down though, there must be something in the presentation of this
particular dataset that is cause issues.
