[Opensim-dev] Creation of 100+ users and TestClient Logins!

[Lake, Dan]

Umar,

There was a bug in TestClient where no region crossings would work. That goes for the 'goto' command for teleporting as well as just walking across a border with 'forward' or other movement commands. That bug was fixed yesterday by lkalif and is in the latest public libomv svn source. I've only tested it with walking across borders, not with the 'goto' teleports. 

For metrics, what question do you want to answer about OpenSim that you are scaling the clients? That will partially determine which metrics you need to capture. We have tried to find the bottlenecks to scaling a scene (objects, scripts, physics, clients, etc) and wanted to know if CPU or network bandwidth was the limiting factor. We have measured CPU and bandwidth as well as line-level profiling of various OpenSim modules. 

Rather than releasing our TestClient patches directly, I am working with the libopenmetaverse team to commit them to their public SVN. For now, the public client has the best available peformance until I can merge our commands to automate the wandering movements.

Dear Dan,

I am using Robust, and running a private grid for my experiments. I have
noticed the issue of sequential execution of actions, and am using a
number of different TestClient instances using different connections.

I have noticed that when we use goto or teleport command for bots and then
apply a command, the server is responds that an action is performed but
the bots are not updating in the scene, any comment on that?

Which metric would be best to check load of a system? CPU usage, Network
Utilisation and anything else? Sorry if that is too stupid to ask!

It would be great to have the code available whenever it is possible.
Thanks again for your help.

Best wishes and have a great day.

Umar
