I suppose this has to be during the issue right? So I should start a conquest map... I'll deliver soon.
There's a portal map call "mark de bench" that starts in new york that's good for testing on. You should use that. When it loads, quickly spawn in and then stand on the tyres & sandbag bit on the right in front of the fire station, point the gun down the street and don't move it again. 5 to 10 minutes is long enough to get a good amount of load going as the vehicles blow up and the buildings collapse.

Note: Don't run through like this guy. It defeats the purpose of testing.
