We've run our tests on university facilities with two adjacent PC labs 
in a semi-closed LAN environment so that we could isolate almost pure 
opensim traffic in there (with some of disk using net storage there was 
a bit of network traffic beside opensim). We had 4 people running around 
and starting and managing everything up. We had scripts that control the 
mouse/keyboard on the client machines. The script can simulate human 
users and work with various (real) clients so that the server can be 
properly tested without having real 70 people in front of all the PCs. 
It worked quite well, with the biggest advantage being repeatability - 
one can repeat the same tests over and over again varying only few of 
the parameters. Also - we can easily make "users" do things together and 
measure that too. It's real hard and tedious work though.

It was in grid mode, with asset server deployed on one machine and all 
the other servers deployed on another machine.
