[Opensim-dev] Profiling complex scenes

[Lake, Dan]

I work at Intel for Mic Bowman. He mentioned a while back that we are developing some workloads for understanding the scalability bottlenecks in OpenSim. I recently created a test which generates 2000 scripted objects which rotate and change color at random intervals. The workload consumed multiple CPU cores with only a single client viewer connected and the frame rate dropped to absolute zero with 10 clients connected. I was then able to reduce the CPU utilization by >80% with a few added lines of code in SceneGraph.cs and Timer.cs. If you are interested in a complete analysis of this workload, please visit the OpenSim profiling wiki page at http://sciencesim.com/wiki/doku.php/opensim/performance_profiling. I will continue to post interesting profiling results from our workloads and ideas about scaling OpenSim based on those results. Your comments or feedback are appreciated.
