Export the missions onto the server.
Load up "400_ai_test_server_editor_bis", start the mission and observe the server FPS.
There are 200 Blufor AI and 200 Opfor AI on opposite ends of the runway which will start moving toward each other and eventually engage in combat.
Note that the FPS reaches a constant level once the AI start moving and then a new constant level once the two sides start shooting at each other.
Then Load up "400_ai_test_server_spawn_bis", start the game and wait 10 seconds for the AI to begin spawning. They will then move out in the exact same manner and the rest is exactly the same as the previous mission.
