OpenSim Performance Tests

OpenSim Performance Tests

System Requirements

Download the latest archive from http://sciencesim.com/repository/vwperf and uncompress to both your simulator and client.

Simulator

Build OpenSim r8311 or later from http://opensimulator.org/wiki/Downloads Note: For SimStats and packet logging, apply ScienceSim measurement patch (available soon)
Configure UGAIM and simulator for your environment
Create a region named “VWPerf”
Create 100 users where firstname = vwperf, lastname = 001 – 100, and password = pass
- Note: Some workloads require only 1-10 users.

Client

Build TestClient r2438 or later from http://libsecondlife.org/wiki/Download
Recommended: Add the libopenmetaverse bin directory to your path

Workloads

Running a workload

Simulator

Start UGAIM and opensim
Ensure all users are logged out
On the opensim console, load the OAR file which corresponds to the desired workload

change region vwperf
load oar <oarfile>.oar.tgz

Client

Run TestClient with the appropriate login_uri and workload script

TestClient.exe --loginuri="<login_uri>" --scriptfile <workload_script>
