I tried using OSG as well. As you mention, the file size was smaller than BIN. However, the data load was even slower than BIN!!! > That said, OSB in general loads very fast.

That is probably what is going on. Let me try your suggestion and report back on what I am getting (probably on Monday - I am travelling over the weekend). > How much of a difference are we talking here anyway? 10% or a > factor of 10? It was more like 4-5x higher with OpenSG. Let me try the above and get back to you. BTW, is there a repository for large VRML data models that I can use for my benchmarks? Something from the CAD space would be preferable. I am currently using PDB (Protein data models) that I convert to VRML and then use in my test app. However, this might not be very exciting/convincing for our client :( The data contains a TONNE of small spheres in 3D space connected by Cylinders and might be messing with the Graph Optimization algorithm that OpenSG uses. - Praveen Using Tomcat but need to do more?
