Objects 01

This workload explores the scaling of the number of scripted objects with periodic updates in a scene and their affect on platform metrics including CPU and network utilization.

Workload Description

The Scene

The scene is a blank flat square region with an object generator in the middle. Each time the command is given, the generator creates 100 objects. Each of those objects changes its rotation and color at random intervals between 1-5 seconds.

Actions

The TestClient connects a single avatar and then repeats the following steps until 1000 updating objects have been created.

  1. Shout more updates causing the object generator to create 100 objects
  2. Sleep for 30 seconds

Results

OpenSim r8311

The spikes in CPU during the object creation phase is apparent. Both the TX bandwidth and CPU usage increase in steps as each set of 100 objects is created. At 1000 objects steady state:

  • TX Bandwidth is ~85KB/s
  • CPU is ~150%.

Note: The bandwith usage is, as expected, exactly 1/10 of that measured during the 10 avatar version of this workload, Objects02.
