font-family:Arial'>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 <a
href="http://sciencesim.com/wiki/doku.php/opensim/performance_profiling">http://sciencesim.com/wiki/doku.php/opensim/performance_profiling</a>.
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.<o:p></o:p></span></font></p>
