We have been having the same issue and haven't found a solution yet either, though it hasn't been our main priority yet. I will be following any responses closely and will contribute if I can.

There are range of things that can cause compilation to be slow, I haven't to head off line right now so will have to leave you with that hint... Robert.

I wonder how to minimize this effect. Clues: -Once the model has been displayed there is no more hiccup. -Differerent models produce different hiccup delays (consistently) -Hiccup problem does not scale with .ive size or nr of polygons -In bad cases I can see the osgstats cull part go to zero for about 1 sec. -Using ProxyNode makes no difference. Suggestions? Some caching options I can try? Anything nasty to look for in the .ive models? (Most are 3DS format made by 3rd party, converted with osgconv, sorry I can't share them) I'm using OSG 3.01, compositeviewer, linux, Nvidia (different cards, same problem.)
