Bufferbloat.net talks about this. The problem is that many home routers do a poor job allocating their resources so if I'm streaming video and you're VOIPing, your latency will go up dramatically since my download is pushing you out. In reality there's enough bandwidth for both of us, but it's getting used poorly. On my setup, loaded latency was over one second (to google.com) compared to under 50ms for unloaded! (Fast.com gives more mild numbers for loaded latency than I observed manually.)
