I haven't tried your example yet, but... To look for a performance difference caused by frustum culling, wouldn't you want your viewpoint _outside_ the group of billboards, so that you can compare performance between "all visible" and "all culled"? If your viewpoint is _inside_ the group, then you have roughly the same number of billboards visible/culled, regardless of your view direction.
