4000 isn't exactly many. If each quad is a separate drawable however it
could induce some performance penalties.

1. use the osgUtil::Optimizer (to convert your quads to triangles and
depending on their structure to on vertex array). Try ALL_OPTIMIZATIONS

2. If you need to simplify you can store the result and use it from then
on.

Can you elaborate on the structure of your scene?

Cheers
Sebastian
