Subject: [Opensim-dev] Profiling complex scenes

 

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.
