[Papervision3D] DAE performance -- best practices to achieve higher FPS?

We've got a few dae files with 2400+ triangles and we're maxing the CPU.
When I strip out interaction and animation, I'm still seeing very low frame
rates. My sense is that the the culprit is the high poly count and the
render loop. As I move the camera in, and reduce the number of triangles
being rendered, the FPS goes up. Are there any recommendations for camera
setting to keep objects off camera for improved FPS? Are there best
practices for collada export settings, other than those docummented in the
Collada class? What can be done to get better FPS and lower CPU usage?
Here is some of what I'm seeing:
The CPU stays pegged in the 80% + range, regardless of triangles.
Processor: AMD Athlon(tm) 64 Processor 3500+, MMX, 3DNow, ~2.2GHz
Memory: 2046MB RAM
This is certainly not your the latest and greatest CPU, but it's doing
better than others in our dev team, and we can expect our customers out
there in web land to have even worse.
Limiting our modeling to 300 triangles really is going to restrict our
ability to deliver 3D experiences to the web.
Thanks in advance for any help!
