A pretty reasonable machine and OS so its not one would suspect general problems with compiling display lists etc. Another thing you could try is to enable compile contexts. Have a look at osgviewer.cpp to see how it switches it one when you use the --cc option. As a general note, the DatabasePager is designed to try and maintain constant framerates and does so by balance how much data is compiled/deleted on each frame - you've already played with the various parameters so will have a bit of grasp of this already. I wrote DatabasePager and do testing and optimizing on it with the data I can get my hands on - most of which is data generated by osgdem/VirtualPlanetBuilder. These databases are pretty regular, and specifically designed with paging in mind so most probably won't be stressing the DatabasePager in the same way that your own datasets. Since my the types of data I have access is a not as wide ranging as the types of data and machines/OS as the community at large can test against I have to rely upon members of the community to pitch in with helping characterise issues and with the optimization of paging support. So I'm open to suggestions on improvements.
